BRDC director says it's 'highly probable' Silverstone will activate a break clause in their F1 contract

It's "highly probable" Silverstone will activate their break clause with Formula 1 to cease holding the British GP after 2019.

The circuit has a contract to host the race until 2027, but with the fee to host the GP increasing each year, Silverstone has the option of ending the contract early.

However, they must exercise that clause before the grand prix weekend gets underway at Silverstone this year.

Philip Walker, a director of the British Racing Drivers' Club (BRDC), who has been involved in talks with Formula 1's new owners Liberty Media, told the Mail on Sunday: "It is highly probable we will have to activate the break clause."

The race could remain on the calendar, though, if Silverstone are able to negotiate a new contract with Liberty Media.

New F1 CEO Chase Carey told SSNHQ in January that they were committed to keeping a British race, but did not guarantee it would remain at Silverstone.

However, Silverstone is the only circuit in the UK capable of hosting the race without significant infrastructure changes.
