Two potential buyers have pulled out of the running to purchase Silverstone leaving the circuit facing an uncertain future.
Jaguar Land Rover and Ginetta sportscar boss Lawrence Tomlinson were among a group of four interested parties keen to acquire the home of the Formula 1 British Grand Prix.
However, both have stepped away from negotiations with current owners the British Racing Drivers Club (BRDC).
Silverstone has been the subject of sale talks since April with the BRDC keen for new investment in the facility amid deepening financial concerns.
British newspaper The Daily Telegraph has reported the BRDC has posted combined net losses of £55.2 million ($88.3m AUD) over the last five years.
Reportedly Jaguar Land Rover had earmarked £33m ($52.5m AUD) of investment in return for a 249-year lease of the venue before electing to abandon its bid.
“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,” read a statement from Jaguar Land Rover.
Ex-Formula 1 driver Jonathan Palmer and owner of Brands Hatch, Oulton Park, Snetterton and Cadwell Park circuits is understood to be one of two remaining parties still in negotiations with the BRDC.
