Mosley is taking legal action against the News of the World
Embattled world motorsport boss Max Mosley insists he has "done nothing wrong" following newspaper allegations about his private life.
The News of the World claimed he took part in a "Nazi-style orgy in a torture dungeon". Mosley has strongly denied his actions had any Nazi connotations.
He is taking legal action over the claims and seeking "unlimited damages".
He has also written to Peter Meyer, head of Germany's national motoring body, ADAC, defending his actions.
His move comes after he was placed under severe pressure from major manufacturers and motoring bodies, including ADAC, to step down.
The Dutch federation KNAF, Israeli body MEMSI and the American Automobile Association have also condemned Mosley.
His latest letter has been circulated to all members of motorsport's world governing body the FIA, as well as the World Motor Sport Council and Senate attending this weekend's Bahrain F1 Grand Prix.
"Had I been caught driving excessively fast on a public road or over the alcohol limit, I should have resigned the same day," Mosley wrote.
I played no role in this, indeed I did my utmost to ensure it remained private. I was the victim of a disgusting conspiracy
"As it is, a scandal paper obtained by illegal means pictures of something I did in private which, although unacceptable to some people, was harmless and completely legal.
"Many people do things in their bedrooms or have personal habits which others find repugnant. But as long as they keep them private, nobody objects.
"The offence seems to be not what I did but the fact that it became public," wrote Mosley, who said he had received support from 20 FIA clubs and representatives of 50 others.
"But I played no role in this, indeed I did my utmost to ensure it remained private. I was the victim of a disgusting conspiracy.
"It goes without saying that the so-called Nazi element is pure fabrication. This will become crystal clear when the matter comes to trial.
"I don't think any of this should affect my work on motoring safety, the environment or the sport," he continued.
"I believe that 21st century adults do not worry about private sexual matters as long as they are legal and harmless.
"I shall put this view to the (FIA) Assembly in due course."
On Thursday, Mosley called an extraordinary meeting of the FIA to discuss the matter, to be held in Paris at the earliest possible date.
