Britain's Lewis Hamilton dominated the Russian Grand Prix to take his ninth win of the year.
The win was his fourth in a row, and extended his championship lead.
Hamilton has now equalled Nigel Mansell's record for most wins by a British driver - 31.
Hamilton's team-mate Nico Rosberg fought back following a first-lap error and took second place.
Rosberg trails Hamilton by 17 points with three races remaining.
