GENEVA, Switzerland (AP) — A leading FIFA anti-corruption adviser resigned Monday, claiming football’s governing body failed to change its culture after bribery and vote-buying scandals.

Alexandra Wrage, president of international compliance expert TRACE, left an advisory panel chaired by Swiss law Professor Mark Pieth which was asked to guide FIFA President Sepp Blatter’s promised modernising reforms.

“(FIFA) remains the closed society that fuelled its problems to begin with,” the United States-based not-for-profit group said in a statement.

Wrage leaves Pieth’s team after it pledged to increase its FIFA work when it met in Switzerland last week for a final scheduled session to decide strategy ahead of a FIFA congress on May 31 in Mauritius.

Pieth, who has had increasingly testy relations with Blatter and his organisation, said they will monitor FIFA beyond the congress.

Blatter has suggested Pieth’s mandate should end at the congress.

Mauritius, FIFA member countries will be asked to approve a slate of reforms agreed to by Blatter and his executive committee last month.

Wrage has previously spoken out in frustration about the FIFA board’s rejection of some modernising proposals, including women candidates for high-profile appointments and greater transparency about salaries and bonuses paid to Blatter and other senior officials.

FIFA declined to comment on Wrage’s resignation.

Meanwhile, FIFA says executive committee member Nicolas Leoz of Paraguay has resigned for health reasons.

Leoz, who is 84 and has undergone several rounds of heart surgery, has been a member of FIFA’s board since 1998. He has been president of CONMEBOL, the South American football confederation, since 1986.
