If Ecclestone, who believes Silverstone is not up to the standards of other circuits, does not accept the offer of around £6m from track owners, the British Racing Drivers' Club (BRDC), Britain could be excluded from next year's Formula One calendar. Standard Sport has learned that BRDC officials, who make no profit from the race, have no scope to increase their offer which is believed to be around £2.5m short of Ecclestone's demands.
