The Football Association have commissioned an independent review by a leading barrister of Lord Triesman's claims of misconduct by four FIFA members during England's 2018 World Cup bid campaign.
James Dingemans QC will examine the evidence and speak to Triesman, who made the allegations under Parliamentary privilege on Tuesday. Dingemans will try to speak to anyone who was present on the occasions referred to Triesman and he will report back to the FA and FIFA by Friday May 27, and his findings made public.
FA chairman David Bernstein said: "It is essential that we determine as soon as possible the weight of evidence behind these serious allegations."
He added: "If Lord Triesman's allegations can't be supported I suppose they will die a death because unsupported allegations will not take anyone very far. If the allegations are to stick with FIFA they need to be supported."
Dingemans has powerful legal credentials - he was senior counsel to the Hutton Inquiry into the depth of former UN weapons inspector David Kelly in 2003 and is a deputy High Court judge. He is also a member of the Rugby Football League's advisory panel.
One Triesman allegation was that FIFA vice-president Jack Warner asked for money to pay for an education centre in Trinidad - Premier League chairman Sir Dave Richards has confirmed the claim and is expected to be interviewed by Dingemans.
Bid officials and a translator may have been present when Triesman alleged Paraguay's FIFA member Nicolas Leoz asked for a knighthood - and they may also be able asked to provide corroboration.
Thailand's Worawi Makudi demanded television rights to an England friendly with the Thai national team, while Brazil's Ricardo Terra Teixeira said "you come and tell me what you have for me", alleged Triesman.
The FA are to decide on who to back in the FIFA presidency before the report is due however, at a board meeting on May 19.
Bernstein said there were three options: to vote for current incumbent Sepp Blatter, his rival Mohamed Bin Hammam or to abstain from voting.
