Not happy: Clinton at the vote announcement for the 2022 World Cup in Zurich in 2010. In the foreground is Mohamed Bin Hammam. Credit:Getty Images "Clinton was fuming," said one well-placed source. "He felt humiliated and felt the decision did not make sense." As Qatar's bid team celebrated and the FIFA president Sepp Blatter declared football was going to "new lands", questions were already being asked about the decision-making process. Why would FIFA award the World Cup to a small Gulf state with no footballing history, let alone stadia, where summer temperatures can reach 50 degrees Celsius? The answer could lie in a series of payments made by a senior Qatari official to various FIFA members. The Qatar 2022 bid committee is adamant that there is no link. In the wake of Qatar's victory, the US and Australian governing bodies, or sources close to them, each hired teams of private detectives who have worked behind the scenes since, interviewing witnesses and obtaining documents in the search for what they were certain was the hidden truth about the motives of FIFA members in voting for Qatar.

Whether there is any connection between these investigations and the leak of documents to The Sunday Times is unclear, but Australia and the US have most to gain if Qatar is stripped of the World Cup. Meanwhile, newspapers have been making their own inquiries into the controversy. In March this year, The Telegraph disclosed that Jack Warner, the former vice-president of FIFA, and his family were paid almost £1.2 million ($2.17 million) by a Qatari firm linked to the World Cup bid. This newspaper also revealed that the 10-year-old daughter of a Brazilian FIFA executive who participated in the 2010 decision had more than £2 million put into a savings account set up in her name. Now The Sunday Times has been given millions of leaked documents that appear to show a further £2 million in bribes that were paid to FIFA members in a plot allegedly organised by Mohammed Bin Hammam, Qatar's most senior football official at the time. Bin Hammam is alleged to have used 10 secret slush funds to make dozens of payments, many of them to accounts controlled by the heads of 30 African football associations who could lobby the continent's four executive members over how to vote.

Bin Hammam was banned from world football in 2011 after he was caught bribing voters in his bid to be elected FIFA president. Now The Telegraph has discovered that Michel Platini, the president of Europe's governing body UEFA, held secret meetings with Bin Hammam, and that Thailand was offered a gas deal in return for its support of the Qatar bid. The clamour for Qatar to be punished has now built such momentum that Australia is said to be ready to re-run its bid if the 2022 tournament is up for grabs again, with the US likely to follow suit. Where that leaves England's World Cup ambitions is less easy to predict. England bid for the 2018 World Cup, given to Russia on the same day as Qatar was awarded the 2022 tournament. British Prime Minister David Cameron and the Duke of Cambridge were among those lobbying FIFA in the run-up to the vote in Switzerland, yet the bid got just two votes and was eliminated in the first round of voting.

Andy Anson, the chief executive of England's bid, said some executive committee members had told lies. He had been confident that England could secure seven votes in the first round, a base that would have provided a platform for victory. "I do feel people let us down, I'd be lying if I said they didn't," he said. "People who promised us our vote obviously went the other way." Even before Russia annexed Crimea, concerns had been raised about the country's human rights and safety record, and there is speculation that if the 2022 vote has to be re-run, the 2018 vote would have to be re-run also. FIFA is already looking at the possibility of moving the 2022 tournament to the winter months, and speculation is growing that Blatter is looking for an excuse to reverse the decision altogether, with health concerns being a potential excuse. A spokesman for the Qatar 2022 bid said Bin Hammam had never worked for the bid and they knew nothing about his activities.
