Former Renault F1 boss Flavio Briatore has said he left the team in order to save it, ahead of the decisive FIA meeting to face allegations of race-fixing.
The Italian, together with director of engineering Pat Symonds, left the team on Wednesday.
The French outfit said in a statement it would not dispute the allegations of fixing the result of last year's Singapore Grand Prix.
Briatore said he felt it was his duty to quit Renault, hoping the FIA will take a more lenient view.
"I was just trying to save the team. It's my duty. That's the reason I've finished," Briatore was quoted as saying by British newspapers.
Briatore and Symonds could potentially be extradited to Singapore to face criminal charges in connection with the race-fixing claims.
The Times newspaper also says there are legal challenges open to Ferrari and its driver, Felipe Massa, who missed out on last year's world drivers' crown by a single point, and to Renault itself, which may want to sue its former employees for allegedly bringing the company's name into disrepute.
