Fifa ethics investigator Michael Garcia delivered his year-in-the-making report into the murky bidding process for the 2018 and 2022 world cups yesterday.

The independent ethics committee suggested that some people could face disciplinary action as the 350-page document “reaches conclusions concerning further action with respect to certain individuals.”

But it will be up to the adjudicatory chamber to decide what that action will be.

German judge Hans-Joachim Eckert is unlikely to make any decision before the end of October and must also decide if the report will be made public.

The ethics committee statement made no reference to any possible action against Russia or Qatar, who won the 2018 and 2022 bids respectively.

Garcia’s report does however recommend changes to the bidding process for future World Cups.

Investigators interviewed “more than 75 witnesses” and compiled “more than 200,000 pages of relevant material,” the committee said.

“Pursuant to the Fifa code of ethics, the adjudicatory chamber will now make a final decision on the report and supplemental reports, including publication.”

Officials from England’s unsuccessful bid for the 2018 World Cup were among those who gave evidence to Garcia and his deputy chairman Cornel Borbely.

The investigation looked into a number of allegations of corruption as well as incentives offered to Fifa executive members such as friendly internationals, development money, commercial opportunities and sponsorships.

US attorney Garcia reported into seven bidding nations while Borbely delivered a separate report into the remaining two.

Garcia could not cover the US because of his nationality and was not allowed to enter Russia as he is barred as part of an ongoing rights row between Washington and Moscow.
