Bernie Ecclestone says the BRDC has just two days to sign a contract if they want to host the 2010 British GP.
Ecclestone has been talking to the British Racing Drivers' Club, who own the Northamptonshire circuit, since it became apparant that Donington Park would not be able to raise the necessary funds to host the event.
The F1 supremo has reportedly offered Silverstone the same contract that they rejected just 18 months ago when the BRDC ruled that it was not financially viable.
Ecclestone, though, has warned that time is running to accept his deal or else Britain will not be on the 2010 calendar.
"They say there is not much between us and them, so they should sign," the F1 supremo told The Guardian.
"Maybe they have lost their pen but if they don't find it in the next day or two then that's it.
"I will pull the race off the calendar and there will be no British Grand Prix to argue about."
