Ross Brawn is not ruling out an expansion of the Formula 1 calendar to include 25 races.
Recently, after Lewis Hamilton and Fernando Alonso threatened to quit if there are 25 races in the future, F1 CEO Chase Carey said that his first priority is to make the 21-race schedule for 2018 as successful as possible.
Now, the rumours about 25 races are back.
Brawn, F1's sporting boss under the new Liberty Media regime, told The Telegraph: "25 races - that's one every other weekend. "Not a bad working life, is it?
"It wasn't so long ago that drivers were testing every week."
Carey has spoken of his desire to mix traditional F1 circuits with exciting new venues like New York or Miami and, in Brawn's words, head to "one or two new continents".
Sean Bratches, the F1 commercial chief, says that the sport has plenty of options to pick from.
"Since I've been here, probably 30 countries, municipalities, principalities have reached out to me interested in bringing Formula 1 to their cities, their countries," he told The AP.
The current championship continues this weekend with the British Grand Prix.
