A fax which contains details of alleged bribery before the 1998 Fifa election has been received by the BBC.

It was sent from a fax machine within the Caf headquarters - the number is stamped at the top of the page.

It is an embarrassment for Blatter's challenger, Caf President Issa Hayatou, who has told his supporters to steer clear of a smear campaign.

Caf vice-president Farah Addo was the first to make allegations that Blatter's election to office four years ago was rigged.

A Swiss court has imposed an injunction on him from repeating his allegations.

Addo, who is also the president of Cecafa, East and Central Africa's regional football body, also said FAs under his jurisdiction would suffer punishment if they voted for Blatter.
