Jenson Button gets past Kimi Raikkonen for was is fourth, as Nico Hulkenberg pits, but the Finn refuses to give the place up and goes side-by-side with the Briton once more.

But Button has the racing line and takes the place and Sebastian Vettel, who has caught the squabbling pair, takes advantage and passes Raikkonen, too. Raikkonen is on 25 lap old tyres, though, so it's no surprise to see him struggling for grip.

Lewis Hamilton and Nico Rosberg trading times at the moment, with the gap stabilised at 0.6 seconds. Meanwhile, there's a great battle between Kimi Raikkonen and Jenson Button over fifth.

"Rosberg went a bit wide there, allowing Hamilton to get back in and continue to put him under pressure. This is fantastic stuff, you feel for both of these guys. Rosberg has been faultless this weekend but is it going to be enough?"

The traffic is doing a good job of getting out of the way of Nico Rosberg and Lewis Hamilton. Eleven laps to go. Gap 0.576 seconds.

"Lewis doesn't look as comfortable on these tyres in the middle sector as he did previously."

Felipe Massa passes Nico Hulkenberg for third, thanks to his much fresher tyres and faster car. He's 28 seconds behind the Mercedes, though. Kimi Raikkonen is 3.9 seconds behind, with Jenson Button 1.4 seconds further back.

Lukie, external: The performance of the two Mercedes is outstanding! Hamilton is so focused after his error, can Nico handle him?

My Old RE teacher, external: What a racer! If Lewis loses the championship because of double points, it will be a true injustice.

Kieron, external: I'm actually gobsmacked, how has Hamilton done it, absolutely amazing.

Replays show that Felipe Massa drove into the wrong pit and had to be waved on into the right one. That would explain why Jenson Button had managed to close the gap so much.
