Jaguar Land Rover has scrapped its plan to buy or lease Silverstone from the British Racing Drivers' Club to throw the circuit's future into uncertainty.
In April the BRDC voted to give Jaguar Land Rover exclusive negotiations over a potential deal to take over the Northamptonshire circuit but the negotiations had faced objection from Porsche with a dispute over exclusive track day use.
A long-term lease of the circuit had been negotiated between the BRDC and Jaguar Land Rover, reported to be worth £33m, but the deal has fallen through with car the manufacturer withdrawing from talks.
"Jaguar Land Rover has ended discussions with the British Racing Drivers' Club for the foreseeable future and is not proceeding with any plans to either lease or purchase Silverstone at this time," a spokesman for Jaguar Land Rover said to Reuters
Silverstone has already seen a bid from Ginetta and boss Laurence Tomlinson fall through after deadlines were missed, while Motorsport Vision owner Jonathan Palmer remains in contention.
The sale or lease of Silverstone was sparked by the BRDC struggling finance position having made a reported £214,000 loss last year.
The first British Grand Prix took place at Silverstone in 1950 and the track currently hosts F1, MotoGP (under a deal with Circuit of Wales), WEC, BTCC, BSB, British GT, Blancpain GT and a number of other motorsport series.
