Red Bull's Sebastian Vettel has moved to within one victory of another World Championship courtesy of winning his fourth straight race at the Korean Grand Prix.
Starting from pole position, the German dominated a race interrupted on two occasions by the safety car to win from Lotus duo Kimi Raikkonen and Romain Grosjean, who finished second and third respectively.

Vettel's nearest rival, Fernando Alonso, could only finish sixth in his Ferrari to fall further behind in his unlikely chase of the championship leader, who can wrap up a fourth world title next week.
Victory at the Suzuka track in Japan will see Vettel gain an unassailable advantage over second-place Alonso, if the Spaniard was to finish eighth or lower.
Reported McLaren target Niko Hulkenberg produced a superb drive in his Sauber to finish just outside of the podium places, with Lewis Hamilton separating him and Alonso in fifth.
Nico Rosberg and Jenson Button were once again further back than they would have liked in seventh and eight respectively, while Felipe Massa and Sergio Perez were also among the points.
