10:30 Good evening everyone and welcome to AUTOSPORT Live for coverage of the 15th round in the 2010 FIA Formula One world championship.

The 5.073 km Marina Bay circuit will host the third Singapore Grand Prix night race, with Fernando Alonso starting from pole position and bidding to become the Prince of darkness, having won in controversial fashion at this venue during the inaugural event in 2008.

Sebastian Vettel leads Red Bull's charge from the front row, having set the pace into of the free practice sessions this weekend. Championship leader Mark Webber starts fifth on the grid and the Australian may be forced into driving a race of consolidation in a bid to preserve his points lead.

Singapore's organisers have put 50 pence in the electricity meter and an already impressive track in the daytime takes on a whole new identity at night. Clear visors allow the watching world to see right into the driver's eyes, while the bodywork of the cars glints magnificently in the artificial light - the event is most certainly spectacular.

The race itself starts at 12:00 GMT - 20:00 local time - but before then we will review Saturday's action at the circuit, in case you missed it, take a look at this afternoon's support race action and focus on some of the major talking points heading into the race.

10:35 Felipe Massa was an early casualty during a hot and humid knockout qualifying session last night after his Ferrari ground to a halt at Turn 14 with a gearbox problem. The unfortunate Brazilian was on his first flying lap of Q1 and, as the red flags came out, it quickly became clear that Massa would not be able to set a time and was eliminated.

He joined the six cars from the three new teams, but this time Virgin Racing got the better of Lotus as Timo Glock posted a lap good enough to secure 18th position. The Lotus pair challenged Glock's time on their final lap but were unable to beat his 1m50.721s.

Q2 delivered the familiar battle between Mercedes and Williams for the lower reaches of the top 10. Toro Rosso has improved its STR 5 this weekend, allowing Alguersuari in particular to get much closer to the coveted 10th position. However, both drivers failed to get through as Michael Schumacher progressed to the shootout for only the second time in the last eight events. Kobayashi produced a great effort in the Sauber to edge out Alguersuari and Hulkenberg in the final moments.

The shootout was always going to be a battle between the top five in the championship and eventually the timesheet reflected just that. Sebastian Vettel made a mistake in the middle sector on his first run and was initially only seventh, while Alonso scorched his way round Marina Bay in 1m45.390s.

Vettel managed to get a clear lap on the final run and slotted into second position, demoting Hamilton to third as Webber came over the line but failed to improve on fourth. Worse was to come for the championship leader, as Button edged his way ahead of the Red Bull driver by just 0.033 seconds to grab that fourth spot.

10:40 Former Formula 1 driver and 'spin and win' Indianapolis 500 winner Danny Sullivan joined the FIA stewards panel this weekend. The American found himself very busy, as a raft of penalties were again handed out on Saturday.

• Lotus Racing was given a reprimand after third practice for releasing Jarno Trulli 'in an unsafe manner' while Lucas di Grassi was coming down the pitlane.

• Formula 1 returnee Christian Klien was clocked in the pitlane at 92.5 km/h, exceeding the 60 km/h speed limit by a huge margin. Klien was fined €6,600. The Austrian felt the need the speed for a second time and was fined accordingly. Timo Glock and Bruno Senna also picked up fines for exceeding the pitlane limit.

• Michael Schumacher was also under scrutiny during qualifying. In Q2, race director Charlie Whiting informed the stewards panel that Schumacher set a personal fastest sector time while yellow flags were displayed. The panel heard evidence and studied the telemetry data and decided that the driver did indeed take appropriate action in reducing speed, so no action was taken.

• BMW Sauber incurred the wrath of the stewards after it released Nick Heidfeld from the pit garage in an unsafe manner into the path of Schumacher as the pair exited the pits to start the final run of Q2. The team was fined $20,000.

10:44 Here's how the championship stands heading into today's race:
World Championship standings, round 14:                

Drivers:                    Constructors:             
 1.  Webber       187        1.  Red Bull-Renault          350
 2.  Hamilton     182        2.  McLaren-Mercedes          347
 3.  Alonso       166        3.  Ferrari                   290
 4.  Button       165        4.  Mercedes                  158
 5.  Vettel       163        5.  Renault                   127
 6.  Massa        124        6.  Force India-Mercedes       58
 7.  Rosberg      112        7.  Williams-Cosworth          47
 8.  Kubica       108        8.  Sauber-Ferrari             27
 9.  Schumacher    46        9.  Toro Rosso-Ferrari         10
10.  Sutil         45       
With 25 points available for race victory, Mark Webber could find his championship lead under serious threat if Hamilton manages to finish ahead of him tonight. If Alonso wins the race and the rest finish in grid order, he will close down the gap to less than 20 points going into the last four rounds.

A non-finish must be avoided at all costs, particularly for those chasing Webber and Hamilton. If the leaders break through 200 points tonight, a DNF for Alonso, Button or Vettel would see them more than 35 points adrift.

10:48 Singapore is enjoying the best weather conditions of the weekend so far today. No rain fell during the morning or afternoon hours - in fact, hardly any rain has fallen across the city-state at all today.

With the early afternoon 'rain zone' out of the way, we are set for a dry, hot and humid 61-lap race this evening, with air temperature hovering at around 29 Celsius, with mostly cloudy skies above.

The humidity will remain high throughout the race at around 80 percent, and with this race schedule to run close to the two-hour time limit, the drivers can expect to ensure the harshest workout of the season.

11:00 Malaysia's Calvin Wong raced to victory in the first of today's support races in Singapore for the Formula BMW Pacific series.

While Colombian youngster Oscar Tunjo led from the start, Wong eventually found a way past the Meritus driver to claim his maiden victory in the championship, while Carlos Sainz Jr. completed the podium.

On Saturday, Russian Daniil Kvyat slipped-up on a damp part of the circuit having led the first lap from pole, handing the advantage to championship leader Richard Bradley before finally taking the lead back with a lap remaining. Wong also started his weekend well with a podium for Mofaz Racing.

Bradley has a healthy lead in the points as the series moves on to support the Korean Grand Prix next month.

11:05 The Formula One drivers parade toured round the Marina Bay circuit a short time ago, with the drivers each having a car of their own to enjoy as they waved to the crowds.

Lewis Hamilton and Mark Webber received enthusiastic cheers, but the most noise was reserved for Singapore debutant Michael Schumacher.

With the parade over, the drivers went back to the team motorhomes to get some cool air and prepare for a long race ahead.

11:10 Craig Baird made it a double in Singapore as he raced to victory in both rounds of the Porsche Carrera Cup Asia. The V8 Supercar regular, who is chasing down Christian Menzel for the Carrera Cup title, fought off stiff competition to take a his first two wins in the series.

Darryl O'Young and Marchy Lee shared the rest of the podium spoils in both races, with the pair swapping around in today's second event, which wrapped up the support programme at Marina Bay.

The Porsche Carrera Cup Asia concludes with a double header at the Shanghai International Circuit next month.

11:15 Here's how the grid will line up this afternoon:

11:20 Fernando Alonso will lead the 24-car field away on the formation lap this evening, with the clear intention of winning for the second time in a row. While the Spaniard has never finished off the podium here, the record of his Ferrari team in the last two years could not be more different - having failed to score points so far at this venue.

The start will obviously be critical, with overtaking opportunities few and far between. Sebastian Vettel will start alongside Alonso for tonight's drag race towards Turn 1 and will be hoping for a better launch than his Red Bull has delivered in recent events.

Lewis Hamilton is third on the grid, with the aim of at least dispatching Vettel by the time the pack reaches the opening complex of corners. Jenson Button may have to watch and wait to see what happens between the leading three on the opening lap, but the reigning champion does need big points to stay in the title fight.

Mark Webber has yet to finish at Marina Bay. The Australian will be looking to put that statistic to bed tonight, although he will have to watch for the advancing charge of Rubens Barrichello and Nico Rosberg off the line. Provided he can see off the challenge from the Williams and Mercedes drivers, Webber can then settle into a race rhythm and take the fight to the four in front.

Michael Schumacher starts from the fifth row of the grid and will be looking for a decent haul of points, but his main concern at the start will come from the hard-charging youngsters Kobayashi and Alguersuari.

11:25 Continuing our look through this evening's grid, we have some familiar names in unfamiliar places.

Sebastien Buemi starts from 13th position this evening and will be directly behind Toro Rosso team-mate Alguersuari on the grid. Petrov is in the mix, while Nick Heidfeld is 14th for his first race this season.

Force India suffered a terrible qualifying performance, so Sutil and Liuzzi will be hoping to move up from 15th and 16th on the grid. Last year Sutil spent the first half of the race staring at Alguersuari's Toro Rosso before losing patience. Chances are he could end up staring at the back of Buemi's car tonight if he doesn't manage to gain several positions off the start.

Nico Hulkenberg drops five spots to 17th following a gearbox change on his Williams FW32. The German has shown strong pace this weekend - on his first visit to Singapore - and he will be keen to make up places, but may find himself in the same situation that befell Sutil last year.

A spirited battle between Virgin Racing and Lotus is on the cards again tonight. The two new teams have raced in very close proximity over the last couple of grands prix and it will be very interesting to see who comes out on top. This will be a race of attrition, and as many are aware, a finish in the top 12 tonight will automatically see one of the new teams take over 10th position in the constructors' championship.

At the back, it would appear as though the HRTs are on a hiding to nothing, with Klien and Senna some way behind the Lotus and Virgin cars on pace. Felipe Massa starts from the back of the grid after his gearbox problem in qualifying yesterday. He should dispatch the six slower cars reasonably quickly, and then the long test of his patience will begin once he catches the back of the midfield battle.

11:30 The pitlane is now open for drivers to make their way around to the grid. The track will be open for 15 minutes and during this time the drivers will make one or more reconnaissance laps towards the grid.

They will want to check important basic functions such as the team radio, throttle, breaks, gearbox and engine settings. They may also play around with the wing level from inside the cockpit.

On an extremely hot and sticky night like we have tonight, the driver's friend will be the drinks bottle, so this also needs to be checked.

11:31 Sebastian Vettel leaves the Red Bull garage and heads out on his lap to the grid.

11:31 Polesitter Fernando Alonso pulls out of the Ferrari garage and heads out for a lap of the circuit.

11:34 Massa has been out for a tour and has returned to the Ferrari garage for checks on the installation of his new engine and gearbox.

11:35 The drivers will quickly find out that there is a lot of dust off the racing line.

11:35 At the start of the race last year, plumes of dust were thrown up into the air by those starting closest to the pitwall.

11:36 Vettel arrives on the grid to take up his second position starting slot. He is pushed there by the mechanics through a packed grid.

11:37 Jenson Button has stepped out of his McLaren on the grid and is off for a chat with his engineers.

11:39 Lewis Hamilton is also now on the grid, climbing out of his McLaren from his third-place spot on the clean side of the track.

11:41 Alonso has been practicing starts at the end of the pitlane but is now heading around to take up his place on the grid.

11:41 Massa is underway again after installation checks but is also popping through the pits to get his car tuned in with a practice launch.

"You have to be very focused, very concentrated. There is no room for mistakes. I think we are up there, and that is what counts. I think we will have a good race."
Sebastian Vettel, grid P2, speaking to BBC TV

11:43 Massa is now on his final tour to take up position at the back of the grid.

11:45 The pitlane has now closed. Any car not on the grid by now, will be required to start from the pitlane - after the rest have taken the start.

11:46 A huge crowd of spectators are packing the circuit and they rise in unison to respect the Singapore national anthem, as it rings out over Marina Bay.

11:47 Jaime Alguersuari did not make it onto the grid before the pits closed. The Spaniard is now forced to start the race from the pitlane.

11:48 Michael Schumacher is getting ready to climb aboard his Mercedes ahead of the German's first start here.

"The soft tyres may only last 10 or 15 laps, so getting the timing right is going to be very important to go onto the primes."
Nico Rosberg, grid P7, speaking to BBC TV

11:50 Felipe Massa is getting final instructions from race engineer Rob Smedley. He has a tough night ahead from the back of the grid.

11:50 Robert Kubica receives last-minute information and data from his race engineer, as he stands on the grid with a damp towel wrapped around his neck to keep cool.

11:54 The problem affecting Jaime Alguersuari's Toro Rosso is cooling related. In Singapore's extreme heat, he could be in for a very early bath.

11:55 There are five minutes to go until the formation lap begins at Marina Bay.

11:56 The track temperature is 31 Celsius, with no chance of rain this evening.

11:59 Rob Smedley leans in over the cockpit of Felipe Massa is Ferrari to give his driver last-minute instructions, as he prepares for the formation lap.

11:59 The engines fire with a minute to go before the formation lap.

12:00 The formation lap begins at Marina Bay. Fernando Alonso leads the field of 23 off the grid, with Jaime Alguersuari to start from the pits.

12:00 The super-soft tyre is the widespread choice of the field, even those outside the top 10 with the freedom to select their tyre compound.

12:01 Alonso makes his way through Turns 7 and 8, as he weaves from side to side to generate heat into his soft tyres.

12:02 The field goes under the grandstand towards the end of the lap, to give the spectators an amazing view of the cars passing underneath them.

12:02 This circuit has proven hard on brakes in the past, with the heavy fuel load adding to the worry with numerous braking zones and high ambient temperatures.

12:02 Alonso makes the turn for home and brings his Ferrari F10 onto the start-finish straight.

12:03 The field is keeping to the right on the racing line before peeling off into their grid positions.

12:03 Alguersuari is released from the Toro Rosso garage and takes up position at the end of the pitlane.

12:03 Massa rolls into position at the rear of the field as we await the lights ...

Lap 1: The five red lights go out and we are racing in Singapore!

Lap 1: Alonso gets off the line well and covers Vettel as they go into Turn 1. Alonso holds the position and leads ahead of Vettel and Hamilton.

Lap 1: Rattling through the Singapore Sling chicane it is Alonso from Vettel, Hamilton, Button and Webber.

Lap 1: There is contact towards the rear of the field with a Force India involved and Massa is up to 21st.

Lap 1: Rosberg is up to sixth, with Kubica seventh and Barrichello down to eighth.

Lap 2: Alguersuari got away after the field had taken the start and he is at the rear of the pack.

Lap 2: Alonso is clear off out in front and leads Vettel by a second into lap two.

Lap 2: Massa is straight into the pits to get rid of the soft tyres. He takes on the hard the compound and gets away quickly.

Lap 2: Behind the championship contenders, Rosberg is sixth, with Kubica seventh, Barrichello eighth and Schumacher in ninth position.

Lap 2: Replays of the start show Button got the early advantage over team-mate Hamilton but the latter fought back to retain grid order.

Lap 3: Nick Heidfeld has been into the pits for a new front wing, as we see Tonio Liuzzi crabbing to a halt on the circuit.

Lap 3: Liuzzi is out of the race with clear suspension damage on the Force India.

Lap 3: The safety car has been deployed.

Lap 3: Petrov is 10th, ahead of Kobayashi 11th, Buemi 12th, Hulkenberg 13th and Sutil in 14th. Kovalainen leads the new teams battle for Lotus in 15th.

Lap 3: Liuzzi's car is unable to be retrieved safely by the marshals at Turn 10, causing the deployment of the safety car.

Lap 3: Liuzzi stopped just after the chicane and pulled to the inside of the circuit.

Lap 3: Webber is rolling the dice and pits for Red Bull!

Lap 3: Petrov, Buemi, Hulkenberg, Sutil, Kovalainen, Trulli, Klien, Alguersuari, di Grassi and Senna are all into the pits to change onto the hard tyres.

Lap 3: It's a big gamble for the championship leader, who will come out with 11 cars ahead still needing to stop.

Lap 4: Nick Heidfeld also came into the pits for a second visit.

Lap 4: Replays show that Heidfeld tried to take on two Force Indias with one Sauber. He rear-ended Sutil before being bashed up the back himself by Liuzzi.

Lap 4: Webber will really need another safety car to make this strategy work, as the midfield contenders he is behind are slower than the leaders.

Lap 5: Vettel is reminded on the radio of the car length rule behind the safety car he fell foul of in Hungary.

Lap 5: Behind the top four, the order has changed thanks to the safety car. Rosberg is now fifth, with Kubica sixth and Barrichello seventh.

Lap 5: Schumacher is eighth with Kobayashi ninth and Glock in 10th.

Lap 5: The safety car will pit at the end of this lap.

Lap 6: The safety car comes into the pitlane and we are racing once again.

Lap 6: Webber immediately tries to make a move on Glock to take over that 10th position. The Australian is through and back into the top 10.

Lap 6: Alonso is away unchallenged and leads from Vettel, Hamilton and Button.

Lap 6: Webber is now right on the back of the Barrichello, Schumacher and Kobayashi trio who are battling the seventh.

Lap 7: Jarno Trulli is touring back to the pits with a puncture, relinquishing 18th position.

Lap 7: Alonso sprints away with a 1m53.462s, pulling back to 1.2s clear of Vettel.

Lap 7: Webber now makes his move and passes Kobayashi at Turn 5. Webber takes over ninth position.

Lap 8: Trulli has made it back to the pits and has his left rear puncture attended to. He rejoins way down the field.

Lap 8: Replays show Hulkenberg making a wild move on Vitaly Petrov in a battle over 13th position. The German takes the place and Massa also takes his opportunity to demote the Russian.

Lap 9: Barrichello is seventh, but losing ground to Kubica. Schumacher is right behind him in eighth with Webber now backed up in traffic in ninth.

Lap 10: The top four are sprinting away with a pace in the 1m53s bracket on the softer tyres. Webber is now 13.2s off the lead.

Lap 11: Webber is right on the case of Schumacher for eigth but he must be worried by the pace of the leaders and hoping for another safety car.

Lap 11: Kobayashi is 10th and is now 4.6 seconds ahead of Glock, who is fighting hard to keep hold of 11th.

Lap 11: Alonso is enjoying the softer tyres out front and sets another fastest lap at 1m52.625s.

Lap 11: Glock is holding up a huge queue of cars. Sutil, Hulkenberg, Massa, Petrov, Buemi and Alguersuari are all in a Glock train.

Lap 11: Webber makes a storming move on Schumacher to grab that eighth place in a vital move to make his strategy pay off.

Lap 12: Webber repeated his move on Kobayashi at Turn 5 to grab eighth from the German after the Mercedes was also wide in the first corners.

Lap 12: Glock crosses the line and is still ahead of that pack of cars, stretching down to 17th place. Kovalainen is 18th with di Grassi 19th.

Lap 12: Vettel has been told to cool his brakes slightly, which will be a worry after Mark Webber's brake failure here last year.

Lap 13: Sutil is the first driver of that group stuck behind Glock as this battle for 11th rages. Sutil may be wary of last year when he lost patience behind Alguersuari.

Lap 13: Alonso now has a useful 2.3 second lead and is now 20.8 seconds clear of Webber.

Lap 13: Nick Heidfeld is 20th and has caught Lucas di Grassi. He should be past the Virgin soon.

Lap 13: The championship leader is harrying Barrichello but his lack of speed at this stage is letting the leaders pull out the gap they need to make a stop.

Lap 14: Hulkenberg runs wide at Turn 7, but is able to continue without any damage to his Williams. He does not lose a position.

Lap 14: Hamilton is just about hanging on in third - 6.2 seconds off the lead - with Button drifting slightly in fourth.

Lap 14: Schumacher is now ninth and 1.8 seconds behind Webber, with Kobayashi 10th. The Glock train is now a full 10 seconds behind Kobayashi.

Lap 14: Vettel sets the fastest first sector as he responds to a recent spurt of pace from Alonso.

Lap 14: Glock is continuing to hold his position in a good display of defensive driving, but others won't be so pleased with it.

Lap 15: Glock still has Sutil 12th, Hulkenberg 13th, Massa 14th, Petrov 15th, Buemi 16th and Alguersuari 17th all nose-to-tail behind him.

Lap 15: Vettel takes the fastest lap as he tells the team he is "not pushing at all".

Lap 15: Nick Heidfeld has passed Lucas di Grassi for 19th position at Turn 7. Heidfeld is now 3.4 seconds behind Kovalainen.

Lap 15: Sutil has made it! Adrian Sutil is through past Glock and up into 11th position.

Lap 16: Hulkenberg is the next man who will have a go at Glock's Virgin as the battle for 12th, as it now is, continues.

Lap 16: Alonso takes away the fastest lap again with a 1m51.709s as he and Vettel begin to pull clear of the McLaren pair.

Lap 16: Hulkenberg has a go at Glock in the opening sequence of corners and he is through. Hulkenberg takes over 12th position.

Lap 17: One by one the drivers will have a go at Glock. Massa got through behind Hulkenberg and is now 13th.

Lap 17: Webber is now 29.9 seconds off the lead and has faded to 1.2 seconds behind Barrichello with a slow lap.

Lap 17: Petrov, Buemi and Alguersuari also passed Glock and the Virgin Racing driver has dropped all the way down to 17th position.

Lap 18: With the Glock entertainment now over, Sutil is in a clear 11th behind Kobayashi, but 14.4 seconds behind the Japanese driver.

Lap 18: Hulkenberg is now 12 and running at the same pace as Sutil, with Massa 13th, Petrov 14th and Buemi 15th.

Lap 18: Michael Schumacher is behind Webber in ninth and hanging on as best he can. The gap between them is 3.6 seconds.

Lap 18: Kobayashi is just one second behind Schumacher in 10th.

Lap 18: The leaders would have been thinking of a stop at this stage, but the soft rubber is peforming well and they need to continue to keep Webber at bay.

Lap 19: Nick Heidfeld has now caught up to the back of Kovalainen's Lotus as a battle for 18th position develops.

Lap 19: The two HRT cars are predictably falling away. Klien is 21st but 14.5 seconds behind di Grassi, with Senna a further five seconds behind in 22nd.

Lap 19: Alonso takes the fastest time once again as he sets a very strong pace out front. He's told to keep going on the radio.

Lap 19: Nick Heidfeld has passed Kovalainen for 18th position.

Lap 19: Vettel is close to Alonso on pace but has fallen 3.4 seconds behind the race leader.

Lap 20: Heidfeld's next target will be Glock, who is 4.7 seconds up the road in 17th.

Lap 20: Webber is not challenging Barrichello at all for seventh and seems to be waiting for the Brazilian to pit.

Lap 21: Schumacher has slipped to 5.2 seconds behind Webber. The German remains in ninth position, but has Kobayashi less than one second behind him.

Lap 21: Sutil in 11th is maintaining a distance of 14 seconds behind Kobayashi. He is unable to close down any of that gap so far.

Lap 21: Championship leader Webber is now 17 seconds behind Button and Rosberg, a further 3 seconds closer, who he will be looking to leapfrong when they stop.

Lap 21: Sutil is struggling the pace on the circuit. Hulkenberg in 12th, Massa 13th, Petrov 14th and Buemi in 15th can all run quicker than him.

Lap 22: Further back, Nick Heidfeld is quickly catching up to the back of Timo Glock and this will soon be a battle for 17th.

Lap 22: Webber is told he is racing Hamilton, who is 20s up the road. He is encouraged to have a go at Barrichello, who is now costing him time.

Lap 22: Heidfeld is now less than one second behind Glock as he catches up to the back of the Virgin.

Lap 22: Hamilton has faded to 15.1 seconds off Alonso's lead, which Vettel has closed to 2.8s in recent laps.

Lap 23: Schumacher is now almost two seconds per lap slower than Webber. He remains in ninth place, but is now 7.6 seconds down on the Australian.

Lap 23: Webber only just survives a very scary moment as he got a big wobble on under braking for Turn 18.

Lap 23: That was very close to disaster for Webber, but he's now back off in pursuit of Barrichello.

Lap 24: The race is beginning to settle down away from the championship contenders. Kobayashi is not able to do anything about Schumacher as they fight for ninth.

Lap 24: Sutil remains in 11th position, 14 seconds behind Kobayashi. Hulkenberg and Massa are in close attendance.

Lap 24: Petrov is 14th, but is now just over two seconds behind Massa, with Buemi 15th and Alguersuari 16th.

Lap 24: Hamilton is being told to find three tenths or half a second as McLaren try to cover the threat from Webber.

Lap 24: Hamilton has a lot of oversteer in that McLaren as his super-soft rear tyres begin to fade.

Lap 24: Glock is 17th and occupying the defensive strategy again - this time against Heidfeld who is all over the back of him.

Lap 25: Heidfeld pulls to the inside and takes a look at the Virgin Racing driver at Turn 7, but isn't really close enough.

Lap 25: Hamilton sets a poor 1m54s lap, having to find his way past Senna's HRT. Webber is now 22.6 seconds behind, which is not yet enough to stop.

Lap 26: The Glock versus Heidfeld battle for 17th is the closest on the circuit currently. They pass the pits and going to another lap with Heidfeld unable to get close enough.

Lap 26: Sutil is gradually eating into that gap between himself and Kobayashi. The German is now 12.4 seconds behind the 10th placed Japanese driver.

Lap 26: Button is only 14 seconds clear of Webber as the latter's strategy looks like it will pay off when the McLarens pit.

Lap 27: Both McLarens continue on a slow pace in the 1m54s as the rear tyres fade further.

Lap 27: Up front, Alonso and Vettel are setting a dominant 1m51s pace with the gap between them now 2.6 seconds.

Lap 27: Heidfeld slices up the inside of Glock at Turn 7. He makes it through, but runs wide and the Virgin driver retakes the place - 17th.

Lap 28: Vettel seems to think he has pace in hand, so is likely waiting to pounce once the leader stops.

Lap 28: Schumacher in ninth is continuously lapping around two seconds per lap slower the Mark Webber. Schumacher is now 14 seconds behind the Australian.

Lap 28: Webber is now just 20s behind Hamilton's McLaren and is almost certain to clear the slower cars once they pit.

Lap 28: Jarno Trulli is back into the pits from 23rd and last position. This is his third visit to the Lotus pit. He is wheeled back into the garage.

Lap 29: Alonso had a poor lap there, passing Kovalainen.

Lap 29: Hamilton finally pits his McLaren for the move to hard tyres.

Lap 30: Vettel is slow away, keeping Alonso comfortably ahead.

Lap 30: Button now pits, putting Rosberg temporarily in the lead.

Lap 30: Button resumes in eighth, behind team-mate Hamilton.

Lap 30: Heidfeld is a full 24.6 seconds behind Alguersuari in 16th, and has little chance of progressing without the help of a safety car.

Lap 31: Replays show Vettel almost stalled on his getaway from the pits, but he is back in pursuit of Alonso on fresh rubber.

Lap 31: It's an interesting decision from Red Bull to pit on the same lap as Alonso, giving up the opportunity of some fast laps from Vettel.

Lap 31: Rosberg pits and will also fall behind Webber and the McLaren pair.

Lap 31: Michael Schumacher pits from ninth position. He takes on the hard tyres and rolls away.

Lap 32: Barrichello is still ahead of Webber and is yet to stop in the Williams. His pace has been reasonable, helping Webber's cause.

Lap 32: Vettel has the bit between his teeth now and he's right with Alonso in a battle for the lead.

Lap 32: Replays show that on the lap before Schumacher stopped, Kobayashi had a massive go up the inside and the pair made heavy side-to-side contact.

Lap 32: The safety car has been deployed.

Lap 33: Clearly, Kobayashi sustained damage. He crashes into the barriers at Turn 18 and is collected by Senna.

Lap 33: Kubica and Barrichello will make a stop. The pack is forming up, meaning they will tumble down the order.

Lap 33: The Sauber and HRT stranded on the racing line exiting Turn 18.

Lap 33: Replays show that Kobayashi appeared to lose his front wing entering the corner and understeered into the barriers.

Lap 33: Alonso leads Vettel as they begin to form up behind the safety car.

Lap 33: Kubica and Barrichello dive into the pits.

Lap 33: They make quick stops and luckily resume seventh and eighth, ahead of the midfield train.

Lap 33: Sebastien Buemi has also been into the pits from 14th position.

Lap 33: Webber is now elevated to that third place his strategy has delivered, with Hamilton now fourth and Button fifth.

Lap 34: Hamilton reports that his drinks system is not working properly.

Lap 34: Now that Senna's car has been removed we can see the extensive damage to the right-hand side of Kobayashi's Sauber as it sits alone on the track.

Lap 34: This second safety car intervention suggests the race will be capped at two hours, with the flag just 54 minutes away.

Lap 34: Klien is wheeled back into the HRT garage with problems.

Lap 34: Behind the five championship contenders, Rosberg is sixth, with Kubica seventh, Barrichello eighth, Sutil ninth and Hulkenberg 10th.

Lap 35: Button is told to try and push at the restart, given that Webber is on old tyres and Red Bull's history of brake problems here.

Lap 35: Massa is 11th ahead of Petrov 12th, Alguersuari 13th, Heidfeld 14th and Schumacher in 15th position.

Lap 35: Buemi is 16th as Kovalainen comes into the pits from 17th.

Lap 35: If it stays like this, the points will read: Webber 202; Hamilton 192; Alonso 192; Vettel 181 and Button 173.

Lap 35: The safety car will pit at the end of this lap.

Lap 36: The safety car comes into the pitlane and we are racing once again.

Lap 36: Alonso is away from Vettel as Webber and Hamilton muscle past the pair of Virgins.

Lap 36: Hamilton tries to pass Webber ... they collide.

Lap 36: Hamilton has damage and he is out again!

Lap 37: Webber now has Button on his tail, as McLaren ponder potentially terminal damage to Hamilton's title campaign.

Lap 37: Webber is asking the team to check if he has damage, while the stewards also look into the incident.

Lap 37: Replays show Hamilton was clear past after taking it three wide with the Virgin, but the door was closing and contact was inevitable.

Lap 38: Webber's pace is good and he seems to have survived that contact. He will extend his advantage at the top of the points considerably.

Lap 39: Alonso leads by two seconds from Vettel, with Webber over five seconds further adrift.

Lap 39: Michael Schumacher and Nick Heidfeld collided in a battle over 14th position. Schumacher had to pit through new front wing and Heidfeld is out of the race.

Lap 40: Rosberg is in fifth position, 1.8 seconds behind Button, with Kubica sixth, Barrichello seventh and Sutil eighth.

Lap 40: Hulkenberg is now ninth in the Williams with Massa one second behind him in 10th. Petrov is 11th with Alguersuari 12th.

Lap 41: Vettel has not given up the chase out front, with the gap just 1.4 seconds between the two.

Lap 41: Buemi is 13th with Kovalainen 14th and Schumacher 54.2 seconds behind the Lotus in 15th , after that change of front wing.

Lap 41: Race control has stated that the incident between Schumacher and Heidfeld is being investigated by the stewards.

Lap 42: Glock is 16th, but 56 seconds behind Schumacher, with di Grassi the last remaining runner in 17th position.

Lap 42: Button is being pushed by his McLaren engineers and is told to push Webber, whose tyres have been in use since the first safety car.

Lap 42: Vettel is now just 1.1 seconds behind Alonso and is not letting the Spaniard get away easily with this race.

Lap 42: Sutil in eighth is coming under strenuous attack from Hulkenberg. The gap between them is 0.7 seconds with Massa a further 0.6 seconds back in 10th.

Lap 43: Vettel is asking his engineer to let him know if the team spot brake problems with his Red Bull.

Lap 43: Schumacher in 15th is catching Kovalainen at almost three seconds per lap. At this current rate he may just catch the Lotus before the end of the race.

Lap 44: Lucas di Grassi pits from 17th position in the Virgin. He rolls back into the race without problem, but remains rooted to the back of the field.

Lap 44: Sutil is clearly holding up the back of cars behind him. The German is still in eighth position, but now has Hulkenberg, Massa, Petrov, Buemi and Alguersuari all nose-to-tail behind him.

Lap 44: Hamilton has arrived back in the pits to contemplate his second costly DNF in a row.

Lap 44: Hulkenberg makes a mistake which allows Massa to take an interested look at the back of the Williams. Massa isn't able to take the place and Hulkenberg holds onto ninth.

Lap 45: Vettel is pushing very hard now and takes the fastest lap out to 1m48.920s. He's just a second behind Alonso and ready to pounce.

Lap 45: Alonso is now closing on traffic in the form of di Grassi's Virgin.

Lap 45: So we have eighth to 13th all within one second of each other. Interestingly, Kovalainen is 14th and only 12 seconds behind this scrap.

Lap 46: The Ferrari team are encouraging Alonso to push in response to Vettel. That is not ideal given the Spaniard's lack of fresh engines.

Lap 46: Kubica makes an unscheduled stop from sixth.

Lap 46: That's likely to a be suspected puncture for Kubica and he resumes behind Alguersuari.

Lap 46: Vettel continues to pile on the pressure and the young German clearly wants victory here tonight.

Lap 47: Kubica is now 13th, but he will quickly catch up to the back of the Sutil train.

Lap 47: But Alonso responds strongly with an impressive fastest lap of 1m48.867s.

Lap 47: Petrov in 10th made a mistake on the last lap and lost a lot of time. He quickly posts a 1m51.903s lap and is about to haul himself back onto the gearbox of Massa.

Lap 47: The stewards will take no further action on that clash between Webber and Hamilton, deeming it a racing incident.

Lap 48: So Sutil is promoted to seventh position after Kubica's stop. He has Hulkenberg eighth, Massa ninth, Petrov 10th and Buemi 11th right behind him.

Lap 48: Kubica is immediately on the attack and has passed Jaime Alguersuari for 12th position.

Lap 49: Alonso sets the fastest lap again at 1m48.822s, stretching his lead to 1.2 seconds.

Lap 49: Kubica quickly catches up to the back of Buemi's Toro Rosso and is set to battle for 11th position.

Lap 50: Kubica makes a move the Singapore sling to the inside of Buemi but the Swiss uses a robust defence to stay ahead.

Lap 50: The next traffic for the lead pair will be Timo Glock, with the leaders looking to put a second lap on the Virgin car.

Lap 50: Kubica was extremely unhappy with Buemi's tactics and raised his left hand in anger.

Lap 51: Glock is extremely slow and the leaders are easily past the Virgin. He looks to be coasting to retirement.

Lap 51: Sutil is somehow managing to stay ahead of all this chaos in the midfield. He remains in seventh position with Hulkenberg and Massa right on his gearbox.

Lap 51: 10 laps or 20 minutes remain in the Singapore Grand Prix.

Lap 51: Kubica has another look at Buemi - this time at Turn 7 - but the Toro Rosso driver keeps the place.

Lap 52: The stewards will take no further action on the incident between Schumacher and Heidfeld either.

Lap 52: Kubica finally gets the job done and passes Buemi to take over 11th position.

Lap 52: Button is told to race Webber to the flag but he is 2.8 seconds behind the final podium place.

Lap 52: Timo Glock comes into the pits and retires. This leaves just two of the six new team cars on the circuit.

Lap 53: Still just 1.1 seconds between Alonso and Vettel out front as the Red Bull pushes the Ferrari to the flag.

Lap 53: Robert Kubica passes team-mate Petrov to take over 10th position. The pair were racing side-by-side over the Anderson Bridge!

Lap 54: Sebastien Buemi has been into the pits from 13th. This could put Kovalainen close to taking the position.

Lap 54: Vettel takes the fastest lap as the lead pair continue to trade blows.

Lap 54: Kubica is charging on and now nails Massa up the inside to take over ninth position.

Lap 54: Kubica's next target is Nico Hulkenberg in the Williams, with Sutil just ahead of the pair of them in seventh.

Lap 54: Kovalainen is now 13th with Schumacher just six seconds behind the Lotus in 14th. Buemi exited the pits in 15th position.

Lap 55: Kubica is showing his overtaking skills as he slices up the inside of Hulkenberg to take over eighth position.

Lap 55: Sutil has spent the last 15 laps holding up five or six cars. Kubica is about to blow right through the lot of them. He is right on Sutil's tail.

Lap 55: Kubica tries to the outside at Turn 7 and it is wonderful move! Kubica breezes round Sutil's Force India to take over seventh place.

Lap 56: Vettel continues to pile on the pressure out front with five laps remaining.

Lap 56: Schumacher is now right on Kovalainen's tail as a battle for 13th place develops.

Lap 57: Buemi is 15th and 6.5 seconds behind the battle between Kovalainen and Schumacher and lapping two seconds per lap quicker on his new tyres.

Lap 57: The leaders are kindly let through by Schumacher and are now trying to lap Kovalainen.

Lap 57: Clever driving by Kovalainen. He lets the leaders through and keeps track position over Schumacher in the process.

Lap 57: The Lotus is cleared, putting Vettel ever closer to leader Alonso.

Lap 58: The gap between Alonso and Vettel is clocked at 0.7 seconds, but the Ferrari is able to maintain track position.

Lap 58: Mark Webber is now 26.7 seconds behind the leaders in third, with Button a further 1.6 seconds behind him in fourth.

Lap 58: The gap with three laps to go is 1.2 seconds, as Alonso just makes sure to get in and out of the corners cleanly.

Lap 59: Kubica has pulled away 13.1 seconds ahead of Sutil since passing him a few laps ago.

Lap 59: There's still five minutes on the clock, meaning the 61 laps will be finished just inside the time limit.

Lap 59: Replays show that Buemi attempted a move for 14th place against Kovalainen and the pair made contact.

Lap 60: Kovalainen's Lotus was tipped into a spin and clearly an oil line was damaged. The Finn was able to rejoin but his car has progressively burst into flames.

Lap 60: Vettel is right with Alonso as they start the final lap.

Lap 61: Kovalainen pulls off with his car ablaze on the pit straight, and immediately set to work with a fire extinguisher.

Lap 61: It is an unfortunate end to Kovalainen's race. Di Grassi takes over the new teams lead for Virgin Racing in 15th position.

Lap 61: The Petrov/Massa/Hulkenberg scrap is right ahead of the leaders as they race around for the final time.

Lap 61: Alonso is now behind Massa but there is little chance for Vettel to do it now.

Lap 61: Sutil is still in eighth place and has Hulkenberg, Massa and Petrov right behind his Force India.

Lap 61: Fernando Alonso wins the Singapore Grand Prix!

14:01 It has been an outstanding afternoon for the Spaniard, resisting immense pressure from Vettel all the way to score a fine, and vital, win.

14:02 Vettel pushed Alonso from lights to flag but in the end he couldn't find a way through, but still scores 18 valuable points.

14:02 Mark Webber grabs the final podium place after a great strategic drive, putting him further out front in the championship standings.

14:02 Jenson Button takes a solid fourth in his McLaren, keeping himself within reach of the championship leaders.

14:02 It's a fine fifth for Rosberg, with Barrichello also impressive in sixth.

14:03 Kubica fought back very strongly from that unscheduled stop and takes seventh.

14:03 Hulkenberg is trying everything to get past Sutil as they approach the final corners.

14:03 But Sutil holds on for eighth position and crosses the line just ahead of Hulkenberg ninth and Massa claims the final point in 10th.

14:04 "We will get them, don't you worry," exclaims a confident Vettel on the team radio.

14:04 Vitaly Petrov finished 11th, out of the points. Alguersuari was 12th with Schumacher 13th, Buemi 14th and di Grassi 15th.

14:05 But Alonso is clearly delighted to defeat Red Bull here, putting him just 11 points off the championship lead.

14:05 So Virgin Racing wins the new teams battle with di Grassi's placing. Kovalainen was classified as the final finisher in 16th position.

14:13 The champagne sprays on the podium and Alonso makes sure that Aldo Costa gets a soaking.

14:13 The drivers pose for the obligatory photograph on the top step of the podium at the end of a very hot and intense Singapore Grand Prix.

14:19 Here's our round up of the race under the lights in Singapore:

Alonso holds off Vettel for vital win

14:20 Four races remain in the 2010 season, providing the Korean event takes place, and the battle for the title will roll on to Japan in two weeks time.

14:24 Alonso is the big mover in the points standings, taking over second after his win this evening. Webber's lead is now 11 points, with Hamilton dropping to 20 behind after a costly retirement that also dents McLaren's advances in the constructors' race.
