James Dall profiles the four Fifa members implicated by Lord Triesman following allegations of "improper and unethical" behaviour during the World Cup 2018 bid process.
Triesman made the claims on Tuesday when speaking before a British parliamentary inquiry into the governance of football in England.
Former Football Association and England 2018 chairman Triesman oversaw England's failed attempt to host the World Cup in seven years' time.
Nicolas LeozAge: 82
Leoz is the president of the South American football confederation Conmebol. The lawyer and former sports journalist has been a Fifa executive member since 1998. Triesman claims Leoz asked for a knighthood, stating: "I said it was completely impossible and we do not operate like that and he just shrugged and walked away". Leoz's spokesman, Nestor Benitez, labelled the accusations "pure fantasy and morbid".
Jack WarnerAge: 68
Warner is a Fifa vice-president, having been a Fifa executive member since 1983. The former lecturer in history was re-elected unanimously as president of the Concacaf federation in spring 2011. Triesman claims Warner asked for around £2.5million to build an education centre in Trinidad, with the cash to be routed through him, and later wanted £500,000 to buy Haiti's World Cup TV rights for the earthquake-hit nation, again to be channelled through him. Warner responded by telling Sky Sports News: "I've never asked Triesman nor any other person, Englishman or otherwise, for any money for my vote at any time."
Ricardo TeixeiraAge: 63
Teixeira is the head of the Brazilian Football Confederation. He has been on the executive committee of Fifa since 1994. Triesman claims Teixeira asked him to "come and tell me what you have got for me", intimating that he wanted something in return for his vote. Teixeira said in a statement: "The president of the CBF [Brazilian Football Confederation] is already taking the relevant judicial measures with a case against Mr David Triesman for the absurd comments which, in truth, attempt to hide his failure in leading the English candidacy since it only obtained one vote... its own."
Worawi MakudiAge: 59
Makudi is the general secretary of the Football Association of Thailand. Triesman claims Makudi wanted to be given the TV rights to a friendly between England and the Thai national team. Triesman said: "I said TV rights should go to the federation of the country staging the game; that was what was believed was the critical thing to making the arrangement a success."
Qatar claims and bannings
Evidence submitted to the committee by the Sunday Times has sparked further controversy. It is claimed that the Fifa vice-president Issa Hayatou from Cameroon and Jacques Anouma from Ivory Coast were paid $1.5m (£900,000) by Qatar in relation to the country's successful 2022 World Cup bid. The 64-year-old Hayatou is the president of the Confederation of African Football while Anouma, 59, is the president of the Ivory Coast Football Federation. The Qatar Football Association has said it "categorically denies" the Sunday Times allegations, adding: "As the Sunday Times itself states, these accusations 'were and remain' unproven. They will remain unproven, because they are false."
Two other Fifa executive committee members, Oceania's Reynald Temarii and the Nigerian Amos Adamu, and four other officials, were suspended last year in the wake of corruption allegations.
