Lewis Hamilton has won the Russian Grand Prix, extending his lead at the top of the F1 World Championship standings

Lewis Hamilton wins the Russian Grand Prix in a Mercedes one-two and Sebastian Vettel has to retire as inner turmoil at Ferrari continues on a frustrating afternoon for Charles Leclerc.

Lewis Hamilton won the Russian Grand Prix, as fortune favoured him and Ferrari floundered.

The world champion moved closer to winning a sixth world title - 73 points clear of nearest challenger and team-mate Valtteri Bottas with 130 remaining - after a virtual safety car was brought out after Sebastian Vettel's red car stopped with engine failure.

Hamilton had not pitted by this point and used the break in racing to go in for a 'free' stop.
