Rosberg had complained about problems with his throttle, and it meant that he ended up conceding the lead to Hamilton before being forced to retire.
Sebastian Vettel took second for Ferrari - and Force India's Sergio Perez managed third after a dramatic last two laps, in which Valtteri Bottas and Kimi Raikkonen both moved through to push him off the podium.
