Lewis Hamilton is the new World Championship leader following victory in the Singapore Grand Prix.

Hamilton's Mercedes came home ahead of Sebastien Vettel's Red Bull. Hamilton had briefly lost the lead to Vettel after his final pit stop but soon retook the front spot for his seventh win of the year.

Nico Rosberg drops to second in the driver's championship standings after withdrawing on lap 14. Rosberg had suffered a steering issue before the formation lap.

The steering wheel did not work and then the whole car wasn't working. We need to find out what the problem was because again we have a reliability problem," Rosberg said after the race.

"We've had a few this year and that's our weakness. We need to get to the bottom of it and make the car 100% reliable.

"It is tough not even leaving the grid. I was hoping the team could fix it after the race had started because it was going on and off."

There are five races remaining in the season, with the next stop at the Japanese Grand Prix at Suzuka in a fortnight's time.
