Bernie Ecclestone believes that FIA president Max Mosley will see through his vow to step down from his role later this year.
Although there has been renewed speculation about Mosley's future plans, on the back of increased tensions between the FIA and the Formula One Teams' Association (FOTA), Ecclestone is sure that his long-time ally will not go back on his intention of moving aside.
"I have no doubt in my mind, as long as I've known Max, he's always done what he said he would do," Ecclestone told The Times
"He's an honourable person. I've always said Max can have a cheque signed by me, without any name or amount on it, because he's a trustworthy guy. So I have no doubt that he will honour all the things he's ever said he will do."
Ecclestone also revealed that Mosley was hurt by the way that FOTA spoke out following the deal that was reached last month to head off the threat of a breakaway championship.
"He was a bit upset after agreements had been made [with Luca Di Montezemolo, the president of Ferrari] to be quiet and not throw stones at each other, and then remarks were made which upset him," he said.
And Ecclestone is confident that the renewed threat of a breakaway championship will not be realised.
"There are probably a couple of people in all the teams who would like to see it happen," he said. "But, no, I don't think it will happen.
"I think people realise that the Formula 1 World Championship has been going for 60 years, it is well established, we've got the best circuits in the world and I don't think they've even thought through really how there could be a breakaway. And if there is, what would our company do?"
