Former BRDC president Derek Warwick says either an affordable new British Grand Prix contract is secured with Liberty Media or the race could be lost.
The former F1 driver stepped down stepped down last October from his position as President of the British Racing Drivers Club, a decision partly justified by his battle to overcome cancer two years ago.
Warwick was still at the helm of the venerable institution however when it triggered a break clause last year in Silverstone's contract to host the British GP, leaving the race just two more years to run.
"The Grand Prix is too expensive, we're losing money and that's why we triggered the break clause," he told the Jersey Evening Post.
"Britain is the home of motor sport. Does that mean there will always be a British Grand Prix? Absolutely not."
The 63-year-old says talks with Liberty Media, F1's owners, will resume later this year. Hopefully with a favorable outcome.
"Of course we want a British Grand Prix and for it to stay at Silverstone, but we want it to be affordable so that we can make just enough money to reinvest in the circuit.
"We can't do that under the present deal," he insisted.
