Lewis Hamilton wins Belgian GP

Lewis Hamilton has extended his lead over Nico Rosberg in the Formula One world championship after romping to victory at the Belgian Grand Prix.

Hamilton, starting from pole for the sixth consecutive race, made no mistake as he eased to the chequered flag in convincing fashion.

Rosberg, slow off the start-line, recovered to finish second with Romain Grosjean benefiting from Sebastian Vettel's late puncture to take the final spot on the podium.
