Good morning everyone, and welcome to live text coverage of the Korean Grand Prix from Yeongam.

Webber has just backed off a touch from Hamilton's rear wing, while Button has maintained a two-second deficit to the Australian.

Hamilton asking for more front wing, but his engineer assures him that it's already at its maximum.

Top 10 (all drivers two stops): Vettel, Hamilton, Webber, Button, Alonso, Massa, Rosberg, Alguersuari, Di Resta, Buemi

Alonso has done it! He did a great job in those last couple of laps, and Massa will be disheartened by that.

The tyres are being prepared for Alonso to come in. He's put in some blistering laps - can he jump ahead of Massa?

No joy for Webber - he cannot find a way past Hamilton. But the longer these two tussle the more comfortable Vettel gets at the head of the field.

Another fastest lap from Alonso, bettered by Vettel straight after with a 1:40.974!

Alonso pushing to extend his advantage in clear air. Vettel has stopped, so for the moment the Ferrari leads thre race.

Massa, having stopped, is behind Buemi and Sutil in 9th place - that's a frustrating place for the Brazilian to be.

Button has closed the gap on these two after his pit stop - just 1.7 seconds behind.

Hamilton is still having a torrid time holding off Webber! Some ferocious side-to-side driving between the two!

Both drivers come out on prime tyres - and Hamilton holds on to his place ahead of the Australian! They rejoin in 6th and 7th.

Webber and Hamilton both come into the pits!

Hamilton's tyres appear to have gone off the boil - Webber putting him under real pressure.

Retirement - Maldonado's come into the pits to end his race.

Vettel set a 1:42.2 on the last lap - that explains why Hamilton struggled to keep pace.

Hamilton's just lost contact with Vettel here - 1.7 seconds the distance. Webber just half a second behind the McLaren.

Schumacher admits he's had a few scraps with Petrov this year. "The first one or two were perhaps on my account, but this one is on his."

Top ten: Vettel, Hamilton, Webber, Button, Massa, Alonso, Alguersuari, Sutil, Di Resta, Buemi

Webber holding on comfortably to the duo in front. Button losing time in fourth - in no man's land behind Webber and ahead of Massa.

Rosberg opts for the pits here - without the advantage of the track position to hold on to.
