Red Bull Racing team boss Christian Horner believes a London Grand Prix would work as a "one-off event", rather than a full-time addition to the Formula 1 calendar.
F1 has been pushing for a race to happen in London for many years now, but it has never materialised due to the vast expense and trouble it would cause, likely gridlocking an already busy capital city for many days as it would require months of planning.
However Liberty Media are looking at the idea of a London GP on the outskirts of the city, where a semi-permanent venue could be constructed. This would be a more feasible approach and it's something the sport's bosses are looking at with interest.
It is however unlikely to happen until 2023 at the earliest as Silverstone recently struck a new deal to host the British GP and it's believed that deal includes a veto on any London race for a period of three years.
Horner says it would be "fantastic" to race on the streets of the capital, but believes it would serve the sport best as a one-off arrangement.
"I think London would need to be one-off event. It’s not the type of venue that would be there every year," he said of the proposal.
"But if ever it was possible, I still think it would be fantastic to see an F1 car race around the streets of London. But it would mean it would be an additional race to Silverstone, which is the natural home of F1."
However if assurances were made that Silverstone would remain on the calendar, Horner says he would be open to having two British races.
"If it’s another fantastic venue and a circuit that adds to a 21-race calendar, and we are fortunate that two of those are in this country, then I’d certainly take it."
Ferrari's Sebastian Vettel disagrees and doesn't think more city based races is what F1 needs at the moment, given the recent expansion into street circuits with the addition of Singapore, Azerbaijan and Vietnam next year.
"I’m happy with Silverstone, let’s put it that way. I think it’s a great place. There’s no problem with putting a great show on here. There’s no problem getting a great crowd.
"I don’t think there’s a strong need to go into the cities. I don’t think there would be more people in the city than here. This is great. Every year I can remember more than 100,000 fans each weekend."
