FIA president Max Mosley has confirmed that he will definitely not stand again in October's election and has endorsed Jean Todt as his preferred candidate.

In a letter sent to all FIA member clubs today, Mosley said that despite pressure from members to restand, he had decided to go through with his decision to step down.

He says that with hard work expecting to result in a new Concorde Agreement being signed to secure F1's future in the next few days, plus other progress in rallying and sportscars, there was little reason for him to go back on his original intention to relinquish the role.

With former World Rally champion Ari Vatanen having put himself forward for the FIA presidency role, Mosley has ended years of speculation about the man he would like to see replace him and backed former Ferrari team principal Jean Todt for the role.
