Zurich: Jack Warner, who had threatened a "tsunami" of revelations about the way soccer is run, quit as FIFA vice president, prompting the sport`s governing body to drop an investigation into bribery allegations against the Trinidadian.
Warner, 68, who had been suspended pending an ethics committee probe into bribery claims, has resigned from all his international soccer posts including the position of CONCACAF president.
"FIFA regrets the turn of events that have led to Mr Warner`s decision," the organisation said in a statement.
"As a consequence of Mr Warner`s self-determined resignation all ethics committee procedures against him have been closed and the presumption of innocence is maintained."
Warner was being investigated in a cash-for-votes scandal relating to the campaign of then-FIFA presidential candidate Mohammed Bin Hammam that rocked soccer`s governing body in the run-up to the June 1 election.
At the centre of the investigation was a meeting with Caribbean Football Union (CFU) members in Trinidad relating to Bin Hammam`s campaign which was organised by Warner and the Qatari.
"This decision (to resign) ... comes during the sequel to the contentious Mohammed bin Hammam meeting in Port of Spain in May with CFU delegates," Warner said in a statement.
"I am convinced, and I am advised by counsel, that since my actions did not extend beyond facilitating the meeting that gave Mr. Bin Hammam an opportunity to pursue his aborted bid for the FIFA presidency, I would be fully exonerated by any objective arbiter.
"I have, nonetheless, arrived at the decision to withdraw from FIFA affairs in order to spare FIFA,CONCACAF and, in particular, CFU and its membership, from further acrimony and divisiveness arising from this and related issues."
Bin Hammam quit the race for the presidency shortly before being suspended in late May along with Warner, paving the way for Sepp Blatter to be re-elected unopposed for a fourth term with an immediate pledge to beef up the fight against corruption.
Warner was until recently an ally of Blatter for the near 30 years. The Trinidadian was involved with FIFA and CONCACAF, the North and Central American and Caribbean soccer confederation.
FIFA observers say Blatter gave him a free hand to run CONCACAF as he saw fit in return for the block support of its 35-member federations.
However, last month Warner threatened to unleash a "football tsunami" by revealing contents of emails with Blatter before later backing down for what he said were legal reasons.
