The report from the American lawyer, which was published by FIFA yesterday following a leak to the German media, cleared Qatar 2022 of any corruption.

It concluded that there was no “evidence of any improper activity by the bid team".

"Although we question the timing of the leak, we welcome the publication of the Garcia report," a statement from Qatar 2022 read.

"We believe that the extent of our cooperation with this investigation and the conclusions drawn represent a vindication of the integrity of our bid.

"We will continue to dedicate ourselves toward delivering on the promises we made during our bid and hosting an historic first FIFA World Cup in the Middle East."

The 430-page document, the contents of which have been the subject of speculation and rumour since Garcia penned the report in 2014, did raise questions over the conduct of Qatar 2022 officials, however.

Those who wanted to bring the 2022 FIFA World Cup to Qatar were accused of "seeking to undermine the integrity of the bidding process".

An extract relating to the Aspire Academy, Qatar's high-performance sports facility opened in Doha in 2004, reads: "At a minimum, the targeting of Aspire-related resources to curry favour with Executive Committee members created the appearance of impropriety."

Garcia also questioned the role of the Qatari Government in the lead-up to the December 2010 vote, where FIFA awarded both the 2018 and 2022 editions of the World Cup.

He wrote that "connections between Government entities and the bid team have helped create an appearance of impropriety".

"Suspicion has lingered that Qatar’s Government financed various investment projects linked to Executive Committee members or their home countries," the report adds.

The report from Garcia, FIFA's former chief investigator, also uncovered evidence that three members of the ruling Executive Committee had been flown to an event in Rio de Janeiro prior to the December 2010 vote on a private jet provided by the Qatar Football Association.

The 10-year-old daughter of former Executive Committee member Ricardo Teixeira also had a significant sum of money deposited into her savings account in the months after the controversial vote, where world football's governing body announced the hosts of both the 2018 and 2022 World Cups.

According to the Daily Telegraph in 2014, this was a total of £1.6 million ($2 million/€1.8 million).

It was paid by former Barcelona president Sandro Rosell, who was recently arrested on suspicion of money-laundering in connection with the ongoing criminal investigation in the United States.

Garcia also found no evidence that Russian bid officials unduly influenced the vote, although they provided little cooperation to the American lawyer's investigation.

The report made uncomfortable reading for members of the English and Australian bids for the 2018 and 2022 tournaments respectively.

Officials representing both bids were revealed to have cooperated extensively with Garcia's team.

Garcia found that former British Prime Minister David Cameron and Prince William were present at a meeting when a vote-trading deal with now disgraced former Executive Committee member Chung Mong-joon of South Korea.

The agreement was that Geoff Thompson, the head of England's 2018 bid and a FIFA vice-president at the time of the controversial vote, would choose South Korea for 2022 and Chung would back England.

"According to their statements, shortly before the vote they attended a meeting at the Baur au Lac hotel in Zurich with England’s Prince William, Prime Minister David Cameron, and FIFA vice-president Mong-Joon Chung of Korea, which was bidding to host the World Cup in 2022," the report says.

"The Prime Minister asked Mr Chung to vote for England’s bid, and Mr Chung responded that he would if Mr Thompson voted for South Korea. 

"Mr Thompson, who said he had been thinking about voting for Korea even before the meeting with Mr Chung, agreed."

Thompson also admitted a plan for England to play a friendly in Thailand to win support for their bid was a "form of bribery".

The proposal was made eight days before the vote but was eventually withdrawn when it became clear Thailand's Executive Committee representative Worawi Makudi had not ticked England's box.

"Top English football officials recognised that arranging friendlies with a team from an executive committee's home country in order to advance the England 2018 bid was improper," Garcia writes.

"Geoff Thompson candidly told the Investigatory Chamber he 'didn't think it was appropriate' to organise the proposed England-Thailand match-up or other friendlies targeting teams associated with executive committee members 'because I think it's a form of bribery'.

"The game's cancellation only underscores the improper relationship between the 24 November 2010 offer to play the game and the 2 December World Cup vote."

Garcia's report identified "conduct by Australia 2022 that may not have met ethics or bid rules".

This included a payment of AUS$500,000 (£295,000/$381,000/€335,000) to a bank account purportedly controlled by the Confederation of North, Central America and Caribbean Association Football for a centre of excellence in Trinidad and Tobago, the home of banned former influential Executive Committee member Jack Warner.

The money never appeared on any CONCACAF statement and it was later revealed that Warner had misappropriated the funds for his personal use after fraudulently obtaining them.

"Football Federation Australia (FFA) reiterates that the financial management of the bid was routinely reported to Government and reviewed by independent external auditors," an FFA statement said. 

"Its payment to CONCACAF was also investigated by the Australian Federal Police which found that no Commonwealth offence was identified.

"FFA has said repeatedly that the bid process for 2018 and 2022 was deeply flawed and that mistakes were made by the Australian bid team.
