Red Bull driver Sebastian Vettel has won the Korean Grand Prix. Team-mate Mark Webber finished second and Fernando Alonso (Ferrari) was third with team-mate Felipe Massa fourth.
McLaren had a race to forget, with Jenson Button taken out in a first lap incident and Lewis Hamilton suffering set-up and tyre wear problems which saw him end in 10th, having started third.
The result means that Vettel has now overtaken Fernando Alonso by six points at the top of the table.
Red Bull lead the Constructors' Championship but Ferreri have overtaken McLaren for second place.
