Hamilton wins as Rosberg retires

Watch highlights as Lewis Hamilton takes the lead of the world championship for the first time since May after victory in the Singapore Grand Prix.

Hamilton's title rival and Mercedes team-mate Nico Rosberg retired with electronics problems to slip three points behind with five races to go and 150 points available.
