The race stewards will investigate the chaotic collisions involving Sebastian Vettel, Max Verstappen and Kimi Raikkonen which resulted in all three retiring on the first lap.
Verstappen was squeezed in the middle of the two Ferraris and was then hit by Raikkonen again at Turn 1 in an incident which also sent Fernando Alonso.
Vettel then lost his front wing and plenty of fluid leaked from his car at the next corner, leaving him facing the oncoming cars and his title rival Lewis Hamilton waltzing through to the take the race lead.
Race Control will talk to the drivers and assess footage before dishing out any subsequent penalties.
Understandably, Vettel was in no mood to talk in the paddock, but said about the start: “I didn’t see that much. I saw Max and then the next thing I see is Max and Kimi hitting me somewhere.
“It doesn’t change much, obviously we are not in the race and can’t show the pace we have.”
