The publication of the Fifa report on the investigation into corruption in the bidding process for the 2018 and 2022 World Cup should put to rest any last doubts about Qatar’s 2022 efforts.

The summary of the original unpublished report does not exonerate Qatar, but did not find any major wrongdoing which would justify a rerun of the vote.

This will come as a relief to the Supreme Committee for Delivery and Legacy (SCDL), which has already spent billions on the preparations. These encompass not only eight stadiums, with construction works started on two, but also massive infrastructure programs.

Qatar is investing $50 billion in preparation for the event, of which less than $4bn is on sports facilities. Infrastructure projects include hotels, roads, the Doha metro and upgrading waterworks to cope with the influx of fans.

The possibility that Qatar could be stripped of the tournament has been a long-running worry for Doha, but now projects can proceed with confidence. Not only has Qatar avoided international embarrassment, but the work and funds of the last four years will not go to waste.

Now all efforts need to be put into delivering projects in time for the tournament. Qatar has experienced issues with coordinating projects, leading it to scale down its investment. The designs for Lusail stadium have been sent back to the drawing board, while deadlines for two main contract stadium bids have been pushed back. The other stadiums are still in their early phases.

Issues remain around the timing of the World Cup, usually held in summer when temperatures reach over 50 degrees in Qatar. The proposed date of November is meeting stiff resistance in Europe, where it would disrupt lucrative national leagues.

Qatar has also been criticised on human rights grounds over its poor treatment of migrant workers.
