A name has now emerged, amid rumours a third candidate for December's FIA presidential elections is looming.
Briton David Ward has already entered the race to de-throne Jean Todt, but F1 chief executive Bernie Ecclestone this week hinted that a third contender might be waiting in the wings.
"Maybe it (Ward's candidature) has opened the door for other potential candidates," he told Auto Motor und Sport.
"They'll say 'If he can, I can too'. So we don't know how many (candidates) there will be in the end. There's still time to submit a nomination," Ecclestone added.
