Prince Ali bin al-Hussein of Jordan, who has been critical of FIFA’s leadership from his seat on the organization’s ruling executive committee, announced Tuesday that he would challenge Sepp Blatter for the FIFA presidency in elections in May.

Prince Ali, 39, is the president of Jordan’s soccer federation, and since 2011, he has been on the governing committee of FIFA, the sport’s world governing body, as a vice president representing Asia. Recently, he has become a leading voice among a younger generation of committee members pushing for transparency and reform of FIFA’s traditionally secretive governing process in the wake of persistent accusations of bribery and other financial misdeeds lodged against the organization’s leaders.

Most recently, Prince Ali and several other members of the committee, known as the ExCo, called for the public release of an internal report investigating the awarding of the 2018 and 2022 World Cups. Questions about the bidding for those tournaments, which were awarded to Russia and Qatar, have led to mounting criticism of FIFA and raised questions about the continuing leadership of Blatter, who is seeking a fifth term as president.

FIFA’s membership will vote for president on May 29 in Zurich in a secret ballot. Blatter turns 79 in March.
