Australia’s Daniel Ricciardo has finished fourth in a rain-affected Japan F1 Grand Prix won by championship leader Lewis Hamilton.

Hamilton won from Mercedes team mate and closest rival Nico Rosberg after the race was red-flagged following 46 of 53 laps.

Ricciardo started from sixth on the grid and made good progress to finish behind third-placed teammate Sebastian Vettel during a race in which vision was severely impaired by spray from the wet track.

Hamilton ducked inside pole-sitter Rosberg at the start of the 29th lap following a crash involving Marussia’s Jules Bianchi.

The Briton now has a 10-point lead over Rosberg with four rounds left this season.

The rain also played havoc early in the race, with the first nine laps run behind the safety car.
