$5m corruption claim over Qatar W'Cup

The Sunday Times has obtained millions of secret documents – emails, letters and bank transfers – which it alleges are proof that the disgraced Qatari football official Mohamed Bin Hammam made payments totalling $5m to football officials in return for their support for the Qatar bid.

Qatar 2022 and Bin Hammam have always strenuously denied the former Fifa vice-president actively lobbied on their behalf in the run-up to the vote in December 2010.

But, according to emails obtained by the Sunday Times and seen by the BBC, it is now clear that Bin Hammam, 65, was lobbying on his country's behalf at least a year before the decision.

The documents also show how Bin Hammam was making payments direct to football officials in Africa to allegedly buy their support for Qatar in the contest.

Qatar strongly deny any wrongdoing and insist that Bin Hammam never had any official role supporting the bid and always acted independently from the Qatar 2022 campaign.

When approached by the Sunday Times to respond to their claims, Bin Hammam's son Hamad Al Abdulla declined to comment on his behalf.

Although the vast majority of the officials did not have a vote, the Sunday Times alleges Bin Hammam's strategy was to win a groundswell of support for the Qatari bid which would then influence the four African Fifa executive committee members who were able to take part in the election.

The Sunday Times also alleges that it has documents which prove Bin Hammam paid 305,000 Euros (£250,000) to cover the legal expenses of another former Fifa executive committee member from Oceania, Reynald Temarii.

Temarii, from Tahiti, was unable to vote in the contest as he had already been suspended by Fifa after he was caught out by a Sunday Times sting asking bogus American bid officials for money in return for his support.

But the paper now alleges that Bin Hammam provided him with financial assistance to allow him to appeal against the Fifa suspension, delaying his removal from the executive committee and blocking his deputy David Chung from voting in the 2022 election.

The paper claims that had Chung been allowed to vote he would have supported Qatar's rivals Australia. Instead there was no representative from Oceania allowed to vote, a decision which may have influenced the outcome in Qatar's favour.

The paper also makes fresh allegations about the relationship between Bin Hammam and his disgraced Fifa ally Jack Warner, from Trinidad.
