Welcome to our LIVE coverage of the British Grand Prix from Silverstone.

Vettel now on the radio, urged to stay away from the kerbs at all costs. He's also being told off about his fuel consumption.

TV producers now showing endless slow-motion replays of the tyre explosions. They do look awfully pretty when they explode!

Rosberg is now warned over the radio to avoid the kerbs, particularly on the high speed corners at turns two and four.

With the various stops and so on, Hamilton has found himself back up to 14th place. Vettel-Rosberg-Sutil the 1-2-3 at the moment.

It's now almost impossible to predict what will happen in the rest of this race - safety car still out with stewards desperately trying to clean the straight where Vergne's tyre went. That was the worst of the explosions so far.

Webber is told over the pit radio that he must be careful because Vettel's tyres had several cuts in them when they examined them after the pit stop.

Pirelli workers are frantically trying to collect bits of rubber to see what's happened. They insisted yesterday that Perez's blowout was caused by a cut to the tyre, but given what we've now seen in the race that seems frankly unlikely...

Vettel is warned over the pit radio that his rear left tyre is now damaged and that he must keep off the kerbs at all costs or suffer the same fate as Hamilton, Massa and Vergne.

The safety car is out! We were just thinking that any more of these tyres blowing and they'd have to seriously think about calling the race off. Charlie Whiting calls out the safety car, probably to get the track cleaned properly and discuss with the teams what to do.

Track temperature is 32 degrees - not crazily high by F1 standards, but it's the combination of a very high speed circuit with heavy early-race fuel loads.

Yellow flags out once again - but there's rubber all over most of the track now.

ANOTHER TYRE BLOWS! IT'S VERGNE! A high-speed tyre explosion as he hammers down the straight at 190mph on the way in to Stowe corner.

Drivers also being warned to try and keep off the curves if they can...

Now Vettel comes into the pits too, and comes back out into the lead with Rosberg back to 3.2 seconds behind.

Rosberg comes in to the pits, and Vettel's lead is up over 18 seconds. He's already almost 40 points clear in the championship - looks like it'll be more than that by the end of the day.

Various drivers being warned over the radio about the punctures - turns four and six are the culprits, around the Arena complex.

For what it's worth Vettel is leading by 3.77 from Rosberg now - though it sort of looks like it'll be a game of exploding tyres more than a normal race.

Alonso's car looks much worse than Hamilton's, wobbling all over the place - much worse for things to happen on a corner than a straight...

Insanity - with the yellow flags out, Webber comes in for a new nose cone, while Fernando Alonso pits as a precaution.

MASSA'S TYRE BLOWS OUT TOO! It's just before the sector where Hamilton's went so can't be debris - it went as he went round a left hander.

The race is yellow flagged, and a string of cars come into the pits. Hamilton now 22nd...!
