Hello and welcome to our live coverage of the third and final practice session ahead of the Korean Grand Prix.

Qualifying coming up in two hours - don't miss it!

Webber comes in second to make it Red Bull one-two, with Rosberg in third and Hamilton fourth. Alonso ends up in fifth with Ferrari team-mate Massa in seventh and Grosjean in between. Raikkonen finishes eighth.

There's the flag! And Vettel tops the timesheets with a 1m37.881s in the third and final practice session!

Hamilton's path is cleared slightly and he moves up to fourth place with a 1m38.332s.

Raikkonen goes fifth fastest, behind the Ferraris pair and the Red Bulls at the top.

Hamilton is in traffic for the time being as he asks his team: "Lots of cars around me, is Webber on a timed lap?"

Vettel hits back with an improvement of over a second to clock 1m37.881s and set a new benchmark!

Boom! With seven minutes left Webber improves once more with a 1m38.018s.

The track is getting busier now as time ticks towards the end of the session. Time to get serious.

Webber's time was not just the quickest of today but also the whole weekend so far.

And the Red Bull man, on super-softs, goes quickest so far today with a time of 1m38.132s.

Webber is the first of that top group to head back out.

Grosjean, Button and Raikkonen are the remaining drivers in the top eight.

With 15 minutes remaining, the top eight drivers are all back in the pits. Hamilton leads, ahead of Webber and Vettel. Alonso and Rosberg complete the top five.

Hamilton now shows his quick form so far this weekend with a 1m38.860s to shunt the two Red Bulls down the pecking order.

Jules Bianchi: “One and three on the understeer side, pointy everywhere else.”

Webber again improves to lower the benchmark time to 1m38.946s.

Felipe Massa is the latest to complain of a problem. “Too much oversteer,” is the Ferrari man's issue.

It's congested on track at the moment, with just four cars left in the garages.

Webber edges ahead of Vettel again, this time with a 1m39.001s.
