The Frenchman did not specify the reasons for the press conference in an email sent to media inviting them to attend and, if he does launch a formal bid for the presidency, he will be the first to do so.
At the end of December 2012, former diplomat Champagne revealed to AFP the reforms that he felt were necessary to put an end to "the crisis of governance" within FIFA, although he made no mention then of any intention to run for the presidency.
Blatter indicated to French television last week that he will announce whether or not he will stand for re-election before the FIFA Congress in Sao Paulo on June 10-11.

Current UEFA president Michel Platini said late last year that he would announce whether or not he was to stand for the FIFA post either during or after the World Cup in Brazil, which starts on June 12.
