Senior football official Issa Hayatou has denied bribery claims made in a BBC documentary and has threatened to sue.
Mr Hayatou, vice-president of football governing body Fifa, says money that the BBC's Panorama alleged was a bribe was in fact paid to the African Confederation).
He says it was part of a sponsorship deal with sports marketing firm ISL.
The BBC say they stand by the claims, and that Mr Hayatou was given several chances to put his version of events.
Mr Hayatou was accused by Panorama alongside two other Fifa officials - Nicolas Leoz, from Paraguay, and Ricardo Teixeira, from Brazil.
All three are on the 22-strong panel currently deciding who will host the World Cup in 2018 and 2022.
The alleged bribes to the three members of Fifa's executive committee were paid by sports marketing company ISL (International Sport and Leisure) and date from 1989 to 1999, Panorama alleged. The company collapsed in 2001.
Fifa granted ISL exclusive rights to market World Cup tournaments to some of the world's biggest brands, and ISL received millions more from negotiating television broadcast rights
