The first back-to-back winner this season turns that in to three in a row and Vettel takes a six point lead in the drivers' championship. Vettel looks delighted and strokes his car in parc ferme - he of course had a failure when leading comfortable here in 2010.

Nabil emails in to say: "Ferrari should have unleashed Massa, as he was faster than Alonso and he might have been able to put more pressure on the Red Bull team probably forcing them to accelerate and with there front tyre wearing problem it could have been a win for Ferrari."

In theory it might have caused a few issues, but Massa ended the race 6.2s behind Alonso and 20s off the lead. Ferrari had tyre issues too it appears.

Red Bull was clearly trying to ensure Vettel didn't go chasing the fastest lap, but he did a personal best on the final lap. It will probably annoy Vettel though that Webber took fastest lap. It's Vettel's fourth win of the year and ominously moves him in to the championship lead with four races remaining.

The national anthems ring out on the podium and we'll bring you a bit of reaction as the top three speak to Johnny Herbert before signing off...

Vettel pours champagne over Herbert, and then says: "Fantastic, I'm very, very happy. Obviously the foundation was to have a good start. It was quite close in the first stint but I felt I had a little bit more left. I think we were all a bit worried about the front tyres ... I have to thank the boys for this one. I think we've done another step and that's exactly what we need."

Webber: "The start wasn't sensational, I'll have to look in to it. It's not the best corner to lead off ... at the end of each stint it was difficult to keep the front right alive. A good drive from Seb and a great day for the team."

Alonso: "We have to be happy with the performance today. We finished third and fourth just behind Red Bull which is difficult to beat. Definitely we are moving in the right direction, we just need one more step to match Red Bull ... then it's going to be a magical last four races."

Lap 55

Vettel is nursing his car home; he seems to have taken the messages seriously. Webber 6.6s clear of Alonso so everyone comfortable. Perez looks set to steal the last point off Hamilton though...

Sebastian Vettel wins the Korean Grand Prix and takes the lead in the drivers' championship.

Webber comes home second to make it a Red Bull one-two, with Alonso third and Massa fourth. Raikkonen is fifth but what of Hamilton? Perez is right on the back of him in the final sector...

Hamilton holds on by just 0.3s, but it's only one point for Hamilton and surely that's the end of his championship hopes.

Ahead of Hamilton were Hulkenberg in sixth, Grosjean seventh, Vergne eighth and Ricciardo ninth.

Lap 54

Perez is only 4.9s behind Hamilton and catching him at three seconds a lap with that problem.

More warnings for Vettel and Webber is only 6.8s behind now. Senna and Maldonado scrap over 14th place in turn three - Maldonado retains his position

Lap 53

Webber now 8.5s behind Vettel and has Alonso 3.6s behind him. Vettel is told told how bad his front right tyre is right now and issued another warning.

What awful luck for Hamilton. A huge bit of astroturf has attached itself to his car and is slowing him massively. He's dropped off the back of the Toro Rossos now.

Lap 52

Vettel told that "anything can happen under braking" now on his right front, and Webber closes the gap to 9.2s. The last thing Vettel needs right now is another big lock-up like on his second stint.

Vergne dives up the inside of Ricciardo for ninth in to turn three, Hamilton can't follow him through yet though.

Lap 51

Vettel has four laps to just ease home. Hulkenberg is catching Raikkonen quickly and is less than 7 seconds behind now.

Ricciardo, Vergne and Hamilton in a row on track now.
