Sebastian Vettel revealed yesterday that he was concerned about the dangers of a possible track invasion when the chequered flag was waved prematurely before he won the Canadian Grand Prix. The flag was waved by model Winnie Harlow who said she was just "following instructions", but it meant the result of the race was decided by the positions at the end of lap 68 instead of lap 70.

Vettel said he realised what had happened on the penultimate lap and sent a radio message to try and help avoid confusion. "Fortunately, we had radio and we had the lap counter in the car and my pit board was accurate," said the four-time world champion Ferrari driver.
