Red Bull's Mark Webber starts on pole for the British Grand Prix at Silverstone ahead of team-mate and Championship leader Sebastian Vettel.

Brilliant driving from Hamilton, who races round the outside of Massa, then nips in front of the Brazilian - cracking stuff! The Brit is suddenly flying...

Every driver is swapping their tyres for soft tyres at the first opportunity now! Vettel and Massa have yet to pit, but Hamilton will capitalise...

Hamilton passes Massa into Brooklands using DRS, but he runs horribly wide and is unable to hold his place on track with the Brazilian regaining his position.

Vettel sets a new fastest lap! The German is really setting his own pace out there, and no one can match it. Massa is really struggling to find any grip and must surely pit now?!

The tyres of the McLaren pair's cars look in a sorry old state already, but that does not prevent Hamilton from putting further pressure on Massa.

Hamilton is told to 'protect his wets' as he continues to put pressure on Massa from fifth spot. Button is just one place behind his team-mate in sixth.

Alonso is now matching Vettel's pace and he is really putting Webber under pressure now. He's flying in the middle sector and could move into second soon.

Webber has 3.5 seconds over Alonso right now, as Rosberg uses DRS to nip past Maldonado into Brooklands. It's very tight between 3-8 spots...

Wow, Vettel is really flying! He's now half a second a lap quicker than Webber and 4.6s clear. Can anyone stop him from this incredible start?

After the crazy initial spray off the track, it is drying quickly now as the cars race round. Schumacher looks set to switch to slicks pretty soon from ninth, while Rosberg is up to 12th.

Kovalainen has already departed to the garage for Lotus, and that looks very gloomy for him. Hamilton and Massa are putting Alonso under immense pressure...

Vettel has a lead of over a second, Massa is all over Button and passes through turn three and Hamiltno is now up to fifth after making yet more progress!

Hamilton storms up to sixth with some frantic and highly effective jinking around on the track to pass Kobayashi, Di Resta and Maldonado...

The race is underway! Vettel pips Webber from the lights, and what a start we have to the British Grand Prix! The track is absolutely soaked, and the spray coming off it is staggering!

Webber comes down through Stowe, and it is nice and dry again. The top ten are all on intermediate tyres. We're ready for the lights...

Part of the track is fine for slicks, but it could be a big risk on other parts. The other option is for the teams to start on intermediates... What to do? There are some very big calls to be made...

The drivers are saying it is very wet on other parts of the circuit - the pit straight is dry, but Copse and the Becketts section is very wet. Everyone is very concerned about their tyre choices right now!

It's not the best weather at Silverstone this afternoon. Temperatures are around 19 degrees, but it's pretty wet and there may well be showers throughout.

Formula 1 faces continued uncertainty over its exhaust regulations after a meeting of the sport's team bosses and technical chiefs at Silverstone failed to reach an agreement. Following a weekend of controversy over the FIA's clampdown on the practice of off-throttle exhaust blowing and the various allowances made to engine builders on reliability grounds, the governing body said it would call off the rule tweak and revert to the pre-Silverstone situation if the teams agreed unanimously.

Webber denied that there was any extra satisfaction from the result because of the controversy over rule adjustments this weekend. Asked if the result was Red Bull's 'reply' to the rules situation, Webber replied: "No, it is not. We are not looking to reply to anything. What has to be reiterated is that our team has turned up very, very early and left very, very late. Every team works hard but this team works incredibly hard."
