Formula 1 Chairman Chase Carey says the sport has options to race elsewhere should negotiations to continue with Silverstone post-2019 fall through.
Silverstone signed a 17-year contract in 2009 but opted to activate a break clause mid-2017 that means next season’s British Grand Prix is scheduled to be the last at the venue.
Commercial chief Sean Bratches hinted on Wednesday that Formula 1 could move the event elsewhere, with his remarks coming hours after confirmation of Vietnam’s place on the 2020 schedule.
Silverstone, host of the inaugural World Championship race in 1950, has been a permanent fixture on the calendar since 1987, having previously alternated with Brands Hatch.
When asked during a Liberty Media’s conference call about the future of the British Grand Prix, Carey replied: “We’ve said in the past this is a sport that seems to like to negotiate in public.
“I don’t think that’s the healthiest way to deal with things as partners.
“We value the Silverstone race but we’ve got to get to a place that works for us.
“Those discussions are ongoing, there’s always other options, and it’s one of those things [that] we make sure is we’re continuing to develop an array of options.
“We’re in a fortunate place right now that we have more places that want to have races than we can race, and that’s a good place to be.
“We’ll continue to develop those options, and make sure we are able to make the best decisions both for fans and for racing and for us as a business, all those things matter, and we’re actively engaged.”
Liberty previously announced plans for a Grand Prix in Miami next year but that has been put on hold, with Carey commenting it is “clearly an ongoing process.
“There’s a lot of parties involved, which is not uncommon when you get a street race that you’ve got macro-parties and micro-parties that are interested.
“It’s a time-consuming process to navigate through all of those, I guess I’d say it’s active.
“The US remains a priority, we’re engaged with discussions elsewhere in the US so it’s not just Miami, and [there’s] opportunities, but we think Miami really could be a great signature event for us worldwide, not just in the US.”
