Lewis Hamilton had his 90th career victory in a chaotic, incident-filled Tuscan Grand Prix.
He out sped Mercedes team-mate Valtteri Bottas and Red Bulls Alex Albon.
There were six cars that retired before a lap of racing had completed.
The race had two red flags, the first caused by a pile-up on the pit straight, the second by a high-speed crash for Lance Stroll.
Hamilton’s win was his sixth in nine races this season and, coupled with a fastest lap secured on the penultimate tour.
It extended his championship lead to 55 points as the season passes halfway, and puts him just one behind Michael Schumacher’s all-time record of wins.
