London - The British Grand Prix was cancelled after torrential rain caused "unsafe" track conditions at Silverstone, organisers announced on Sunday.
With heavy rain lashing down throughout the weekend, the MotoGP race had been brought forward from its original 12:00 GMT start time to 10:30 GMT in a bid to beat the weather.
But the rain continued to pour down on Sunday morning, forcing officials to delay the start time and then cancel the event for safety reasons.
After several false starts in which a provisional start time for the race was set and then scrapped, a meeting between officials and the teams was convened.
It was quickly agreed that the track wasn't fit for competition given the high risk of issues with the rain-sodden surface.
"After a meeting between IRTA officials and the MotoGP riders, a decision has been made to cancel the GoPro British Grand Prix due to track conditions being deemed too unsafe," a statement on the official MotoGP website announced.
A press conference was scheduled for 15:15 GMT to discuss the situation, with doubts over whether the race would be rearranged after MotoGP said there was "no option" to hold it on Monday.
