Sebastian Vettel won his first Grand Prix of the season in Singapore, but his victory caused a lot of controversy within the Ferrari camp.

From third on the grid Vettel undercut Charles Leclerc in the other Ferrari which saw him leapfrog teammate who had begun in pole position.

Leclerc was angry with the team’s decision to pit Vettel early, which allowed him to get ahead of his teammate as Leclerc emerged from a pit stop a lap later.

It was a much needed win for Vettel and a one-two for Ferrari for the first time since 2017.

"I'm very happy. It was a great race. First of all big congratulations to the team," said Vettel, who said he was surprised to come out ahead of the field.

Celebrations between the two drivers after the race were somewhat muted with Leclerc visibly frustrated with how it ended.

Red Bull's Max Verstappen finished third ahead of Lewis Hamilton but the Briton is still clear at the top of the title race with 296 points. Valtteri Bottas is his closest rival, albeit 65 points behind.

Leclerc and Verstappen are both tied on points in third, 32 points further adrift.
