The public has a "full right to know" the contents of the ethics investigation into the bidding process for the 2018 and 2022 World Cups, FIFA executive committee member Prince Ali bin Al Hussein of Jordan said.
"In the interest of full transparency, I believe it is important that the much-anticipated report on the ethics investigation that is crucial to ensuring good governance at FIFA is fully disclosed and open to the public," he said on Twitter on Tuesday.
"This will only help the football community move ahead in reforming our institutions in the best interest of the sport," added Prince Ali, who is the Asian vice-president on the executive committee.
"The entire football family as well as its sponsors and those who follow the game worldwide have a full right to know the contents of the report in the spirit of complete openness."
FIFA's ethics committee is investigating whether there is any corruption in the turbulent bidding process four years ago which ended in the 2018 World Cup being awarded to Russia and the 2022 tournament to Qatar.
Former US attorney Michael Garcia, FIFA’s ethics investigator, recently completed his report but it has not been made public.
It is now being scrutinised by German judge Hans-Joachim Eckert who heads the adjudicatory chamber of FIFA's ethics committee.
A final decision is not due until the spring and even then FIFA's ethics code, under a section entitled "confidentiality”, states that "only the final decisions already notified to the addressees may be made public."
On Friday, Garcia himself criticised the lack of transparency surrounding his investigation, adding that he is restricted by the code as to what he could make public.
"As a general matter, I think that the more that is public and the more that people can see what is done and agree with what was done, or disagree with what is done...then those issues can be resolved and the organisation can move on,” he said during a conference on sports in ethics held at FIFA headquarters.
"Beyond any particular case, the public have to have confidence that the process is working in a fair way."
FIFA and Qatar World Cup organisers have been fending off allegations of corruption ever since the Gulf state was awarded the tournament, while Qatar has also been criticised over its treatment of migrant workers in the construction industry.
Qatar has denied the allegations.
On Monday, Germany's Theo Zwanziger, another FIFA executive committee member, predicted that the 2022 tournament would not take place there because of the scorching heat.
"I personally think that in the end the 2022 World Cup will not take place in Qatar," the former German football federation president told Sport Bild.
"Medics say that they cannot accept responsibility with a World Cup taking place under these conditions," he said.
"They may be able to cool the stadiums but a World Cup does not take place only there," Zwanziger said.
"Fans from around the world will be coming and travelling in this heat and the first life-threatening case will trigger an investigation by a state prosecutor. That is not something that FIFA Exco members want to answer for."
