ZURICH (AFP) - Fifa president Sepp Blatter cancelled his much-anticipated press conference scheduled in Zurich on Friday, world football's governing body announced.
No reason was given for the decision.
The conference was initially due to start at 1pm local time. It was then delayed by one hour before being cancelled altogether.
It would have been Blatter's first opportunity to face the media following last week's suspension of Jerome Valcke, Fifa's general secretary and his right-hand man.
Valcke was moved aside over allegations that he was part of a black market ticket selling scheme.
Valcke fiercely denies the allegations.
On Thursday, Switzerland's attorney general Michael Lauber's office said Fifa had agreed to hand over Valcke's e-mails, evidence Lauber had demanded as part of an investigation into World Cup bidding.
