Mosley dismisses calls for FIA shake-up

Stewart has been outspoken this year in the FIA's handling of the spying affair, and in a recent speech at the Monaco Business forum he felt it was time to eradicate doubts that he felt existed over the FIA's even-handedness.

"There must be the removal of any concern over the genuine independence and impartiality in the governance of the sport by the FIA," Stewart said.

But Mosley, who already belittled the former world champion in September, tagging him a "certified half-wit", has again dismissed Stewart's claims, and the FIA president admitted that calls for changes are only making him more determined to carry on.

"Dear old Jackie," Mosley said in an interview this weekend with the Guardian. "He knows nothing about sports governance. Because he never stops talking, he doesn't know much about anything, actually. He just talks.

"So when people like that say it, you think, 'I just can't.' It's very childish, I suppose. The real moment to go is when you lose interest in your ideas. As far as I go, the only thing that keeps me doing it is new ideas and new technologies and steering the thing in a sensible direction. That's the motivator."

Mosley also said he was undecided on whether or not he would stand for another term as president.

"I sometimes say jokingly that is it sensible that Formula One is run by two old-age pensioners? I don't think of myself like that, and Bernie certainly doesn't, but we are, and I think you have to recognise that at a certain point you've got to stop."
