Lewis Hamilton won a chaotic Belgian Grand Prix at Spa-Francorchamps after leading from the first corner to the end of the race.
Hamilton was in a class of his own during a race that saw two safety car periods and a flurry of pitstops during two rain showers.
The McLaren driver moves back to the head of the F1 World Championship after erstwhile leader Mark Webber finished second.
Hamilton took the lead at the start of the race when polesitter Webber had a poor start and dropped to sixth.
The McLaren driver was never seriously challenged thereafter despite two trips off the circuit during the rainfall at the Bus Stop chicane on the opening lap and at the Rivage hairpin late in the race.
Renault's Robert Kubica was third, Ferrari's Felipe Massa was fourth and Force India's Adrian Sutil was fifth.
Championship contenders Jenson Button, Sebastian Vettel and Fernando Alonso suffered disastrous races at the Belgian circuit.
