Asian Football Confederation president Mohamed Bin Hammam was ordered to face an ethics hearing after an insider alleged bribery, reported Reuters.

However, Hammam denied any wrongdoing just days before the June 1 elections for presidency in which he is challenging Sepp Blatter, head of soccer's world governing body.

Bin Hammam said that he is confident there is no charge to answer'', after Federation International de Football Association (FIFA) investigated into bribery allegations against him.

The bribery charges against bin Hammam were not staged by any news organization but by a FIFA insider, Chuck Blazer, who is in the executive committee. Blazer is the general secretary of North American, Central American and Caribbean region, or Concacaf, in which the United States plays.

FIFA said Qatar's Bin Hammam and Trinidad & Tobago's Warner are going to face ethics committee hearing in Zurich on Sunday, three days before the governing body's presidential election, along with two officials from the Caribbean Football Union (CFU).

This move is little more than a tactic being used by those who have no confidence in their own ability to emerge successfully from the FIFA presidential election,” Bin Hammam said. Here I completely deny any allegations of wrongdoing either intentionally or unknowingly while I was in the Caribbean.

The meeting by FIFA was organized so that Bin Hammam could state his election case to the delegates. He had been unable to attend the CONCACAF Congress in Miami on May 3 after being denied a visa for the United States.

Bin Hammam has used the campaign to call for reform in FIFA, which has been mired in claims of corruption surrounding last year's vote to choose hosts for the 2018 and 2022 World Cups.

The bribery charges center held a meeting on May 10 and 11 that was attended by bin Hammam, Warner and about two dozen soccer delegates from the Caribbean region. Each of 208 member federations votes for the presidential election.

Two weeks ago, Warner came under scrutiny in a British parliamentary inquiry, he was accused of requesting $4 million for an education center and $800,000 to buy Haiti’s television rights fees in exchange for voting for England to host the 2018 World Cup.

In a statement on Wednesday, Warner said he was “not aware of any wrongdoing” regarding the latest bribery charge.

“It is interesting to note the timing of these allegations and the hearing scheduled days before the FIFA presidential election,” Warner said.
