FIFA has requested evidence to support English claims that six executive committee members were involved in bribery during the 2018 and 2022 World Cup bidding contests.
FIFA President Sepp Blatter, meanwhile, promised to resolve the crisis before he comes up for re-election on June 1.
“We have to deal with this matter before the Congress and not just kick it out of the minds of Fifa and (say) ‘we will deal with it afterwards’.
“We have to do it now immediately. We have exactly three weeks to do so,” Blatter said in an interview with Al-Jazeera.
Blatter is seeking a fourth and final four-year term against Qatari challenger Mohamed bin Hammam, who was a key figure in his country’s victorious bid to host the 2022 World Cup.
Following Tuesday’s allegations made during a British Parliamentary inquiry, FIFA secretary general Jerome Valcke wrote to England’s Football Association asking for a complete report plus “all documentary evidence” from David Triesman, the former leader of England’s 2018 bid.
Triesman claimed that four FIFA officials – Jack Warner, Nicolas Leoz, Ricardo Teixeira and Worawi Makudi – requested bribes in the 2018 bidding.
The British parliamentary committee was also told that Qatar paid $1.5 million to two more FIFA officials, Issa Hayatou and Jacques Anouma, in ecxchange for their support for Qatar in the 2022 contest.
FIFA said it has asked The Sunday Times for more evidence of information it received from a whistleblower within Qatar’s bid.
Valcke requested detailed evidence in order to “examine the situation thoroughly and with clear-sightedness,” FIFA said.
