10:30 Hello everyone and welcome to AUTOSPORT Live for the seventh round in the 2010 FIA Formula 1 world championship.

Istanbul Park is the venue this weekend for the sixth Turkish Grand Prix, but up front it's a familiar story with the dominant Red Bull Racing team once again on pole position thanks to Mark Webber's superb qualifying performance.

The rarely used 5.338 km circuit has presented the drivers with a stiff challenge so far. Turns 1 and 8 have seen most of the action with many off-track excursions and we expect more of the same in this afternoon's 58-lap race.

The race itself begins at 12:00 GMT, but before then we will set the scene by reviewing yesterday's qualifying session, update you on today's weather conditions and support card activity, and focus on some of the major talking points heading into the race.

10:35 Red Bull secured its seventh pole out of seven in 2010 as joint championship leader Mark Webber continued his dazzling run of form in qualifying.

The Australian, who seems to be driving better than ever, took advantage of problems affecting team-mate Sebastian Vettel and posted 1m26.295s to claim a hat-trick of poles. To compound Vettel's woes still further, Lewis Hamilton delivered a supreme effort to split the blue cars, landing a spot on the front row for the first time this season.

Vettel ended up on row two alongside Jenson Button, and was clearly displeased with the recent turn of events, as he sat in the post-qualifying press conference shaking his head.

Michael Schumacher took a strong fifth, around half-a-second off the pace, just ahead of team-mate Nico Rosberg. Robert Kubica was seventh for Renault, but Ferrari is having a nightmare weekend at its landmark 800th world championship grand prix.

Felipe Massa could only manage eighth spot in the first of the F10s, but a sudden lack of speed in qualifying saw Bahrain GP winner Fernando Alonso unceremoniously dumped out of Q2. The Spaniard starts today's event from a lowly 12th place.

Webber secures third pole in a row

10:40 Weather conditions are fantastic around Istanbul this morning, mirroring what we saw on Friday for practice.

Patches of mainly light cloud could drift over from the west as we move through the afternoon, but on the whole we expect very bright conditions for the race with no chance of rain.

Temperatures are on the rise once again over Saturday's values. The maximum in the air will nudge towards the 30 degree mark, but with much more sunshine than yesterday, track temperature will climb steadily to approximately 50 Celsius.

10:45 Rio Haryanto took a lights to flag victory in today’s GP3 Series sprint race at Istanbul Park. The Manor driver started from pole ahead of MW Arden’s Miki Monras and held his advantage over the Spaniard into the first corner, gradually building a gap to secure a winning margin of 2.2s by the flag.

Monras had an uneventful run to second, with ART’s Alexander Rossi completing the podium after passing the Jenzer Motorsport car of Nico Muller for third at Turn 1 midway through the race.

Daniel Morad (Status) and Felipe Guimaraes completed the top six.

10:50 Dani Clos claimed his maiden GP2 victory with a dominant win in this sprint race this morning. The Spaniard held off the challenge of Racing Engineering team-mate Christian Vietoris into the first corner and eventually took the flag 8.8 seconds clear to become the sixth GP2 winner in six races this year.

Vietoris had looked on course to make it a comfortable one-two for the Spanish team but was forced out with a mechanical problem, which left Rapax driver Luiz Razia to take an easy runner-up spot.

Addax's Giedo van de Garde claimed third place after getting ahead of third-place starter Michael Herck (DPR) on the opening lap, but he had to absorb pressure from iSport's David Valsecchi throughout the race. Herck followed home Valsecchi to take fifth place, with race one winner Pastor Maldonado (Rapax) taking the final point for sixth.

Clos claims first GP2 win in Turkey

10:55 The final piece of supporting action saw the Formula 1 drivers appear in front of the sparse Turkish crowd for the first time today for the traditional parade round the circuit.

One of the quietest tours ended without any major talking points, as the 24 competitors got the opportunity to chat to each other on the flatbed truck.

Once the lap had ended, they headed back towards the paddock and the team hospitality units to continue final preparations for the race.

11:05 Motor racing enthusiasts love to debate and discuss the action on track, and the live forum at the bottom of the screen is your chance to let everyone know your thoughts on events as they unfold at the circuit.

• Can Mark Webber do it again and take a commanding lead in the drivers' championship?

• How will Fernando Alonso get on starting from 12th position? The Spaniard needs to claw his way towards a podium spot today to stay in touch in the title race.

• Will any of the new team drivers get near the points this afternoon? This could be a race of attrition. When you factor in the off-track excursions that are likely here, then it's just possible that one of the Lotus drivers could sneak a tenth place finish.

11:10 In two weeks' time, AUTOSPORT Live will take on two high profile events simultaneously for our biggest motorsport weekend yet.

The 78th Le Mans 24 Hours sees Peugeot and Audi lock horns once again at La Sarthe. Another wonderful battle is in prospect between the two giants of prototype racing, with a superb supporting cast featuring the likes of the Mansell family racing together for the first time. We will be on hand with round-the-clock commentary of the race on Saturday 12th and Sunday 13th June.

Formula 1 travels across the pond to Canada and we will have the usual extensive service covering weather, all three practice sessions, qualifying and of course race day from Montreal, as Red Bull looks to hammer home its speed advantage over the rest of the field.

So plan your diary and stock up the food supplies for the biggest motorsport festival of the year with AUTOSPORT Live.

11:15 The pitlane will open in 15 minutes, allowing the drivers onto the circuit for the first time today.

Numerous checks have to be carried out on the lap to the grid. The drivers will want to get an early feel for track conditions following the support races that have taken place since qualifying.

Also, they will run through the throttle, braking and gearbox functions, check the front-to-rear brake balance and, for those that have the option, check the F-duct to make sure it is working well.

Sebastian Vettel will have more to do than most, following the roll-bar problem that thwarted his qualifying effort on Saturday.

11:20 While Mark Webber was clearly delighted with his third-straight pole position, the team most buoyed by yesterday's qualifying result was McLaren. With Hamilton second and Button fourth, the Woking-based squad has a great opportunity to deny the championship leaders a perfect result this afternoon.

"I think we are a lot closer to Red Bull than I expected this weekend," said Jenson Button after the grid was set yesterday.

Although the RB6 was dominant through the middle sector, with incredible aerodynamic grip around Turn 8, the MP4-25 in Hamilton's hands was quicker in the first and final sectors and is particularly strong on the long run down to the final complex of corners - where some of Hamilton's finest overtaking moves have been delivered in GP2 and F1.

"If I can get close enough to Mark then without a doubt I will be taking the opportunity," said Hamilton after qualifying.

Meanwhile, Vettel will be keen to make up for a disappointing qualifying and should be strong now the errant roll-bar on his car has been repaired.

Behind the top four is the prospect of an interesting in-house battle at Mercedes, chased by the ever-impressive Robert Kubica and Felipe Massa in the leading Ferrari.

Fernando Alonso will be the man to watch in the middle of the grid as he attempts to battle forward from 12th, but could face stiff competition from the likes of Sutil and Petrov on a weekend where the Ferrari F10 is clearly not working well.

11:25 Continuing our look through the field, we switch attention briefly to the second half of the grid and who is likely to provide the entertainment.

Pedro de la Rosa starts from 13th place and is hoping to put an end to a terrible string of results so far in 2010. The Spaniard is in with a good chance of points, but he has to stay out of trouble and equally the Sauber C29 must get him to the end to have a chance.

The Williams and Toro Rosso drivers seem to be locked together this weekend. One to watch in this quartet will be Rubens Barrichello. The Brazilian has completed in every race held at Istanbul Park and he knows more than anyone that this will be a race full of minor mistakes for the inexperienced drivers.

At the back we have the prospect of the closest battle so far between the three new teams - Lotus, Virgin and HRT. Heikki Kovalainen struggled in qualifying but still did enough to claim 20th place on the grid behind team-mate Jarno Trulli. The Italian looks for once to have the upper hand and seems the likely candidate to try and stay close to the established teams.

Bruno Senna achieved one small target for Hispania, out-qualifying Lucas di Grassi in 22nd place. Senna will bid to keep ahead of the Virgin driver in the early stages and we could see some spirited fighting for track position at the rear, with Karun Chandhok ready to pick up the pieces from any altercations. But Virgin has raised the stakes this morning by changing di Grassi's engine for the race.

11:30 The pitlane is now open for the drivers to take their cars around on a lap to the grid.

11:30 Lucas di Grassi is the first man to head out with that new engine in his Virgin entry.

11:31 Many of the drivers will plan a couple of laps to the grid with a pause in their pit box to test a launch as there is no area for practice starts here.

11:31 Mark Webber heads out for a lap in the pole-sitting Red Bull, with a set of hard tyres on the car at the moment.

11:32 Vettel has a brief dice with one of the Toro Rosso drivers on his way to the grid, with the latter peeling off into the pits.

11:33 Air temperature is up to 29 degrees while track temperature is now very warm at 49 Celsius.

11:33 The engine fires on Lewis Hamilton's McLaren and he heads out to take up his first front row slot of the year.

11:34 Schumacher's Mercedes is trollied out into the pitlane so the German can practice a launch from his pit box.

11:36 Red Bull mechanics are once again protecting the rear of the RB6 from prying eyes as Vettel steps out of his car.

11:36 Jenson Button is now on his lap to the grid with a set of soft tyres bolted onto the McLaren. He will be looking for a podium today.

11:37 The Ferrari pair have also been practicing launches in the pitlane but are now in place on the grid.

11:41 With most of the cars now in position, the team mechanics are now working to keep everything cool in the warm conditions ahead of the race.

11:42 Bernie Ecclestone patrols the grid as preparations continue around the cars.

11:44 There are problems for Lucas di Grassi in the Virgin and his car is up on stands in the garage.

11:45 This will be a great boost to HRT drivers Senna and Chandhok, who now have one less direct competitor to worry about.

11:45 Di Grassi had that engine change overnight and it may be that a problem has been detected with the installation of the fresh Cosworth.

11:45 On the flip side, it also means that once again we won't see 24 cars react to the lights at the start of the race.

11:45 With the pits now closed, the Virgin will be forced to start from the pitlane.

11:46 The smallest crowd of the year rises to respect the Turkish national anthem, as it rings out over the circuit's public address system.

11:48 Enthusiastic applause for the anthem in the main grandstand as it ends. Meantime, the work continues to fettle the machinery ahead of the race.

11:50 Kovalainen gets his final instructions from Lotus technical director Mike Gascoyne.

11:51 Felipe Massa pulls on his balaclava as the Brazilian prepares to climb aboard his Ferrari.

11:53 A few more clouds are slowly moving in across the circuit, but conditions will remain mostly sunny and very warm for the race.

11:54 The drivers are now getting comfortable in their cars with the formation lap just over five minutes away.

11:55 There are just five minutes to go before the formation lap begins at Istanbul Park.

11:55 Feverish work continues in the Virgin garage as the mechanics attempt to ready Lucas di Grassi's car for the race.

11:56 Di Grassi will start the race from the pitlane at best - providing Virgin can fix a late oil leak with that car.

11:58 Track temperature has dropped a click to 48 degrees with air temperature at 28 Celsius on a hot afternoon.

11:59 The engines fire with just a minute to go now before the cars roll off the grid.

12:00 The formation lap gets underway and Mark Webber leads the 23 cars round on the final lap before the start of the race.

12:00 Fernando Alonso, in 12th, is matching the top ten runners by starting on the softer tyre.

12:00 All 23 cars down there on the grid get away, with Lucas di Grassi to start from the pitlane.

12:01 Webber leads them through the high-speed Turn 8 and down the hill towards the final portion of the lap.

12:02 There are a lot of marbles off line in Turn 8, deposited by the GP2 and GP3 support races earlier this morning.

12:02 Working hard to get racing temperature into the tyres and brakes, Webber begins to slow the pace down approaching the final corners.

12:02 He makes the turn for home and Webber begins to move towards pole position.

12:03 The front few rows are in position and the field is forming up nicely.

We await the lights ...

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

Lap 1: Webber sprints away and is into Turn 1 first with Vettel up there in second ahead of Hamilton.

Lap 1: Hamilton retakes second from Vettel out of Turn 3 as the fight begins.

Lap 1: Through Turn 8 it is Webber from Hamilton, Vettel, Schumacher Button and Rosberg.

Lap 1: Hamilton fought back bravely on Vettel at Turn 4 and is back in pursuit of leader Webber.

Lap 1: Fernando Alonso has made a poor start in the Ferrari and runs in 13th in the early going.

Lap 2: Button wants his place back too and the McLaren man is around Schumacher with a great move at Turn 12.

Lap 2: Hulkenberg pits the Williams at the end of the first lap. It appears that he made contact with Sutil in Turn 1.

Lap 2: So up front it is back to grid order with Webber from Hamilton, Vettel, Button, Schumacher and Rosberg after a frantic opening lap.

Lap 2: Hulkenberg rejoins but Buemi is into the pits with a puncture on the Toro Rosso.

Lap 2: Hamilton is not letting Webber get away and is under a second behind the leader.

Lap 3: Buemi rejoins in last position after a change of tyres.

Lap 3: Hamilton is right on the gearbox of the Red Bull at Turn 12 and a fight for the lead is on in Turkey.

Lap 3: Fernando Alonso has passed De la Rosa for 12th position. He is now right on the tail of the other Sauber of Kobayashi.

Lap 3: Behind the Mercedes pair, Kubica is seventh followed by Massa, Petrov and Sutil.

Lap 4: Jarno Trulli has made a brilliant start, passing Barrichello in the confusion in Turn 1. Barrichello takes 16th place from the Lotus driver.

Lap 4: Hamilton is eyeing that signature move into Turn 12 and the McLaren is right with the leader once again.

Lap 4: Replays of the start show the McLarens struggled off the dirty side and both were beaten to the first corner but fought back bravely on the first lap.

Lap 5: Kubica and Massa also had a very close dice in the opening corners but continued without damage.

Lap 5: Hamilton is just half a second behind leader Webber, with Vettel closing slightly on the pair.

Lap 5: Hulkenberg will be the next driver on the move at the rear of the field. He is 23rd and about to catch the Chandhok-Di Grassi battle for 21st.

Lap 6: Hamilton is looking very racy here but loses out heavily as the Red Bull flies through Turn 8.

Lap 6: Bruno Senna is another who made a very good start. He is 19th at the moment, benefitting from those two pitstops, but he also nailed Glock somewhere in the opening lap.

Lap 6: Vettel in third and Button in fourth continue to catch the lead battle, which could soon be a four-way fight.

Lap 6: Meanwhile, Kubica is tailing Rosberg's Mercedes in a battle for sixth, with Massa right behind them.

Lap 6: Hulkenberg has passed Di Grassi and then quickly sees off Chandhok in Turn 8. The Williams is now up to 21st place.

Lap 7: Hamilton, Vettel and Webber are trading the fastest lap with the McLaren fastest last time around.

Lap 7: Outside the top ten we have Kobayashi hanging on to 11th place with Alonso unable to make an impression so far.

Lap 7: The lead gap is just 0.4 seconds as Hamilton harries Webber.

Lap 8: De la Rosa is 13th and dropping back from the Ferrari, with Alguersuari 14th and Liuzzi 15th. Barrichello in 16th is concerned that his rear wing may be broken.

Lap 8: Petrov and Sutil are now closing on that scrap between Rosberg, Kubica and Massa to make a five-car train.

Lap 8: Trulli is 17th and inevitably dropping back to the tune of eight seconds from Barrichello's Williams. Kovalainen is 18th and close behind.

Lap 9: Senna is holding onto 19th place but now has Glock and the recovering Hulkenberg right on his tail - a three-car scrap at the back.

Lap 9: Hulkenberg passes Glock for 20th position on the run down the hill to Turn 10.

Lap 9: Hamilton continues to put pressure on the leader but things are closely balanced with the Red Bull quick through Turn 8 and the McLaren closing again down the back straight.

Lap 10: Senna in 19th is now coming under attack from Hulkenberg. The Williams is through and the Lotus pair are five seconds ahead.

Lap 10: Hamilton is still just half a second off the lead, with Vettel a further two seconds back in third.

Lap 10: Buemi is last in 24th, but he is recovering quickly. He is 25 seconds behind the new team cars but closing in at a rate of five seconds per lap.

Lap 11: Button is just 1.2 seconds behind Vettel in fourth, with Schumacher fading away from the leaders in fifth, 8.1 seconds back.

Lap 11: Rubens Barrichello in 16th is continuing on with the rear wing that he suspects may be damaged. He is right on the tail of Liuzzi.

Lap 11: Hamilton sets the fastest lap at a 1m32.422s.

Lap 11: Kobayashi pits from 11th place in the Sauber. This releases Alonso into some clean air.

Lap 11: The F-duct is providing a major advantage for the McLaren down the straights but Webber is still far quicker through the high-speed Turn 8.

Lap 12: Barrichello also pits from 16th and gets routine service. The mechanics also very quickly check the condition of that rear wing.

Lap 12: Alonso is in the pits from 11th in a move to cover the pitstop of Kobayashi.

Lap 12: The McLaren team will surely be happy with this pace as both its drivers continue to pressure the Red Bull pair.

Lap 12: Alonso takes on hard tyres and rejoins the race.

Lap 13: Hamilton is right on the Red Bull this time but he still can't find an open door at Turn 12.

Lap 13: Alonso rejoined the race ahead of Kobayashi so the reaction strategy works for the Ferrari driver. Alonso takes over 11th place.

Lap 13: Webber leads by 0.4 seconds from Hamilton, with Vettel a further 2.2 seconds behind. Button is fourth and only 1.2 seconds behind the other Red Bull.

Lap 14: Petrov, Sutil and De la Rosa all pit together from ninth, tenth and 11th. They rejoin in the same order.

Lap 14: McLaren will be confident of leapfrogging the Red Bulls at the stops as they appear to hold a race pace advantage today.

Lap 14: Liuzzi pits from tenth place in the Force India.

Lap 14: Massa and Kubica pit, taking hard tyres. Both resume without a change of order.

Lap 15: Alonso sets his quickest lap of the race so far. 1m32.717s helps him to just 1.2 seconds behind Petrov now. They are 11th and 12th at the moment.

Lap 15: Vettel pits from third as the scrap continues between Webber and Hamilton.

Lap 15: Schumacher also pits his Mercedes. Button will be looking for a rapid lap now to beat the Red Bull when he stops.

Lap 15: Button is the fastest man through the first sector as he pushes to leapfrog Vettel.

Lap 16: Heikki Kovalainen has passed Lotus team-mate Jarno Trulli while the faster cars all pit. The Lotus pair are 16th and 17th currently.

Lap 16: Vettel has resumed behind Rosberg and this is very costly for the German.

Lap 16: Hamilton chases Webber in to the pitlane.

Lap 16: The Red Bull stop is quicker and the pair resume.

Lap 16: That slow stop has cost Hamilton heavily as he resumes behind Vettel.

Lap 17: Replays show a fumble on the left rear and that has put Hamilton behind the Red Bull pair.

Lap 17: Meanwhile, Jenson Button sets the fastest lap and he could do well by running longer than the others.

Lap 18: Button is the only man yet to pit and leads from Webber, Vettel, Hamilton, Schumacher and Rosberg.

Lap 18: Button is in the pits this time.

Lap 18: Alonso is now tenth but is not managing to pull in the Renault of Petrov. In fact, Petrov pulls away on that lap by almost one second.

Lap 18: It is a rapid stop for Button but he resumes fourth behind team-mate Hamilton.

Lap 19: So it is now a Red Bull one-two with Webber leading from Vettel and the McLaren pair of Hamilton and Button.

Lap 19: Behind the top four and this wonderful scrap at the front, Schumacher is 15 seconds down in fifth with Rosberg sixth and Kubica seventh.

Lap 19: Hamilton is fired up now and tries a move around the outside of Vettel at Turn 12, but he can't make it stick.

Lap 19: Massa is eighth and has Petrov now homing in on him in ninth. Alonso still tenth and Kobayashi 11th, with Sutil 12th.

Lap 20: With no more stops expected, Hamilton will now have to pass both Red Bulls on the road if he wants to win this race.

Lap 20: De la Rosa is 13th, followed by Alguersuari 14th, Liuzzi 15th and Hulkenberg in 16th.

Lap 20: Heikki Kovalainen is 17th but now has Barrichello all over him in 18th place.

Lap 20: The lead group were approaching Chandhok's HRT but clear him easily.

Lap 21: Barrichello sends a move on Kovalainen and it sticks. The Brazilian takes over 17th place in the Williams.

Lap 21: Hamilton sets the fastest lap as a spectacular four-way scrap continues for the lead of the Turkish Grand Prix.

Lap 21: Trulli is now 19th with Glock 20th, Senna 21st, Buemi now 22nd, Di Grassi 23rd and Chandhok now falling away in last position.

Lap 22: The Meteo France rain radar at the circuit is showing a sudden shower that has built in just the last few minutes. We could have a dramatic change in conditions soon.

Lap 22: The heat of the day has caused a convective shower to build up. The cloud is quite dark and rain can clearly be seen in the distance.

Lap 23: The teams are now expecting rain in the next eight minutes.

Lap 23: It is status quo in the top four as the teams ponder the potentially spectacular impact of that incoming shower.

Lap 23: Bruno Senna has been into the pits and has dropped down the order to 23rd position. Now Chandhok pits from last for the first time today.

Lap 24: Fernando Alonso has fallen back to 2.4 seconds behind Petrov as he continues circulating in tenth position.

Lap 24: Hamilton is still right on the case of Vettel as the skies continue to darken.

Lap 24: Schumacher in fifth is now a full 20 seconds behind the leading quartet. He has Rosberg two seconds behind him.

Lap 25: Button is warned of the rain on the radio and told that it could be his opportunity. The world champion is fourth, behind team-mate Hamilton.

Lap 25: The Meteo France information now states that the shower will arrive in the next fifteen minutes. If rain does fall it will completely change the complexion of the race.

Lap 25: Webber sets the fastest lap but is just over a second ahead of the scrap between Vettel and Hamilton.

Lap 26: Schumacher continues edging away from Rosberg. It's now the younger Mercedes driver that is coming under pressure from Kubica, Massa and Petrov.

Lap 28: The field is split into two distinct groups. You have the leading four fighting for the win, then Schumacher 22 seconds adrift.

He is now almost three seconds ahead of Rosberg, who in turn has Kubica, Massa, Petrov and a recovering Alonso now close behind him.

Lap 28: Webber laps Buemi's Toro Rosso as he moves out of the way from the leaders.

Lap 28: It is still a tight one-two-three-four over the line with just 2.6s covering the lead pack.

Lap 28: Kobayashi is doing his best to hang onto that group of five cars but is 2.5s behind them in 11th place.

Lap 30: The leaders are now closing on the back of the Lotus pair.

Lap 30: Rosberg in sixth falls to three seconds behind Schumacher. Kubica, Massa, Petrov and Alonso are all there close behind.

Lap 30: The track temperature has dipped to 39 Celsius with the overcast conditions.

Lap 30: Kubica is now much closer to Rosberg and fancies a run at the Mercedes on the run to Turn 12. He isn't close enough this time.

Lap 31: Vettel is looking quite racy at the moment and is right on the tail of leader, and team-mate, Webber.

Lap 32: Rubens Barrichello passes team-mate Hulkenberg for 16th place. They are on their own with Liuzzi 12 seconds up the road in 15th.

Lap 32: Meteo France has revised its expectations of the rain, suggesting it is now due at 16:00 local time - in nine minutes.

Lap 32: Bruno Senna gets a run at Lucas di Grassi and he passes the Virgin for 22nd place.

Lap 32: Hamilton is now back on the gearbox of Vettel with the fastest lap in his McLaren.

Lap 33: No latest news on the rain but overcast conditions continue above the circuit. The track temperature has dropped down to 39 degrees.

Lap 33: Button sets the fastest lap and is still just three seconds behind leader Webber.

Lap 33: Meteo France now predicts that rain may arrive in 15 minutes time - the second extension of their prediction since we first heard about the possibility of rain.

Lap 34: Nico Hulkenberg is now beginning to struggle badly on his worn set of tyres in 17th place.

Lap 34: Buemi is 18th and has finally passed all six of the new team cars after pitting to replace a punctured tyre at the end of lap one.

Lap 35: Button is setting the pace at the moment and is closing up on team-mate Hamilton to tighten the leading train of cars.

Lap 35: Glock pits from 21st position in the Virgin and rejoins.

Lap 35: Michael Schumacher is still fifth but has fallen to over 33 seconds behind the leading four cars.

Lap 35: A bad lap for Lotus - Jarno Trulli pulls off to the side of the track and retirement after a strong early run in the race.

Lap 36: Kovalainen pits on the same lap from 19th place and it is a very long stop.

Lap 36: Problems for Kovalainen as he is wheeled into the garage for repairs.

Lap 37: The problem with convective showers is that they can dissipate just as quickly as they build.

But this time it looks like the shower will hit as the first spots of moisture begin to show on Lewis Hamilton's on-board camera.

Lap 37: This tense lead train continues to circulate as the McLaren and Red Bull teams wait to see if it rains any time soon.

Lap 38: Mike Gascoyne of Lotus confirms a double hydraulics failure on the same lap for Trulli and Kovalainen.

Lap 38: Alonso in tenth has caught Petrov and now has a go round the outside of the Renault into the switchback section at Turn 12.

Lap 39: Alonso isn't able to get the job done on this occasion and will have to try again.

Lap 39: Vettel is the man putting on the pressure at the moment as he pushes leader Webber very hard.

Lap 39: Hulkenberg pits from 17th place and gets that worn set of tyres that he took at the end of the first lap replaced.

Lap 40: Webber is wide as he laps Senna's HRT and Vettel is looking if he can make a move here.

Lap 40: Vettel pulls a move and they crash!
