Fifa Vice President Prince Ali Bin Al Hussein of Jordan has confirmed he will challenge Sepp Blatter for the presidency of the organisation, saying he will put the sport first.
Prince Ali, who is president of the Jordanian FA, is currently a member of the Fifa Executive Committee.
"I am seeking the presidency of Fifa because I believe it is time to shift the focus away from administrative controversy and back to sport," he said in a statement on www.jfa.com.
"This was not an easy decision. It came after careful consideration and many discussions with respected Fifa colleagues over the last few months.
"The message I heard, over and over, was that it is time for a change. The world's game deserves a world-class governing body - an International Federation that is a service organisation and a model of ethics, transparency and good governance."
Football's world governing body FIFA said the controversial report into the bidding for the Russia and Qatar World Cups will be published after all although the tournaments will still take place as planned.

Uefa president Michel Platini says the credibility of Fifa depends on the report in the World Cup bidding process.
Platini, who has been frequently critical of Sepp Blatter, was speaking after Fifa announced they would release Michael Garcia's findings.
"This is a step in right direction. Let us hope that the (corruption) report can now be published as quickly as possible. The credibility of Fifa depends on it," Platini told the media on Friday.
Fifa president Sepp Blatter says he will turn round the organisation following a period of 'crisis'.
Blatter, who intends to stand for the presidency for a fifth time, was speaking after it was announced Michael Garcia's report into the World Cup bidding process would be published.
Blatter told journalists: "It's not the first time we have been in a critical situation. We will fight. But we need your help, you are making public opinion.
"We have been in a crisis, but today the crisis stopped. I will bring back FIFA. But not alone. I need my Exco & the FIFA family."

Blatter said "external legal experts" supported the view that "there are no legal grounds" to revoke the controversial vote in 2010 to award the World Cups to the respective nations.
Fifa president Sepp Blatter says he is pleased that Michael Garcia's report into the World Cup bidding process will be published.
Blatter hopes the publication will help boost public confidence in the organisation after the summary of the report was heavily criticised.
"I am pleased they have agreed. It has been a long process to arrive at this point and I understand the views of those who have been critical," Blatter said in a statement.
"We have always been determined that the truth should be known.
"It is clear that while a summary of the report was issued, the publication of this report has become a barrier to rebuilding public confidence and trust in FIFA.
"Now it is important that the work of the Ethics Committee continues and that any instances of wrongdoing are fully investigated and their perpetrators pursued and sanctioned."
Fifa's executive committee has unanimously agreed to publish Michael Garcia's reporting into the World Cup bidding process.
The decision was taken following a meeting in Morocco, but there was no vote taken. The report will not be published until charges against three Fifa ExCo members are resolved.
Domenico Scala, the head of FIFA's audit and compliance committee, gave a presentation to the ExCo suggesting the report should be published in an "appropriate form" - with all names and other details redacted.
The President of Fifa, Sepp Blatter, has said that he is "surprised" at the decision of chief ethics investigator Michael Garcia to resign after his his appeal against the findings which cleared Qatar and Russia to host the 2022 and 2018 World Cups was rejected.
In an official statement, Mr Blatter said:
I am surprised by Mr Garcia’s decision. The work of the Ethics Committee will nonetheless continue and will be a central part of the discussions at the ExCo meeting in the next two days.
Fifa said it will appoint an acting chairman to serve as a replacement for Mr Garcia on the Ethics Committee, pending an election to replace him.
US lawyer Michael Garcia has resigned his position as Fifa's chief ethics investigator in protest.
In his resignation letter, Mr Garcia said he disagreed with governing body of football's decision to reject his appeal against the findings which cleared Qatar and Russia to host the 2022 and 2018 World Cups.
He also mentions a "lack of leadership" within Fifa, saying he cannot change the culture of the world governing body.
It now appears that, at least for the foreseeable future, the Eckert Decision will stand as the final word on the 2018/2022 FIFA World Cup bidding process. While the Appeal Committee's decision notes that further appeal may be taken to the Court of Arbitration for Sport, I have concluded that such a course of action would not be practicable in this case.
No independent governance committee, investigator, or arbitration panel can change the culture of an organization. And while the November 13, 2014, Eckert Decision made me lose confidence in the independence of the Adjudicatory Chamber, it is the lack of leadership on these issues within FIFA that leads me to conclude that my role in this process is at an end.
Accordingly, effective today, December 17, 2014, I am resigning as independent Chairman of the Investigatory Chamber of the FIFA Ethics Committee.
