The British Touring Car Championship has been forced to abandon plans to race at British Grand Prix weekend. Angry series director Alan Gow claimed team organisation BETA had turned down the Silverstone showcase "for their own financial reasons".
He said: "I fear that the negative decision taken by BETA means that it is a great opportunity squandered.
Once a regular fixture on Grand Prix day, the BTCC series last supported F1 at Silverstone seven years ago.
Gow added: "This would have made a tremendous spectacle and an incredible showcase for our cars, manufacturers, teams, drivers and sponsors in front of the biggest audience of the year."
