FIFA's probe into the controversial bidding race for the 2018 and 2022 World Cups was thrown into turmoil Thursday after its own investigator Michael Garcia complained that a summary of his report misrepresented his conclusions.

Football's world governing body had earlier cleared Qatar and Russia of corruption and ruled out a re-vote for the tournaments despite widespread allegations of wrongdoing.

Garcia, a former New York district attorney, spent 18 months investigating the controversial World Cup race that ended with the selection of Russia for 2018 and Qatar for 2022.
