Former Football Association chairman Lord Triesman claims four Fifa members sought "bribes" in return for backing England's failed 2018 World Cup bid.
Triesman - who was initially chairman of England's bid - made the allegations about Jack Warner, Nicolas Leoz, Ricardo Teixeira and Worawi Makudi.
He said their behaviour was "below what would be ethically acceptable".
However, Fifa vice-president Warner said the allegations made against him by Triesman were "a piece of nonsense".
Speaking to Sky Sports News, he added: "I've never asked Triesman nor any other person, Englishman or otherwise, for any money for my vote at any time.
"In the English campaign, before Triesman was unceremoniously kicked out, I've spoken to him on his initiative on only three occasions, while I've spoken to his other colleagues on other occasions and not one of them will ever corroborate his bit of trivia.

Blatter wants Triesman evidence
"I have been in Fifa for 29 years and this will astound many, I'm sure - including people like David Dein [international president of England 2018 bid] and Geoff Thompson [head of England's 2018 bid]."
In a seoerate development, it was also claimed on Tuesday that two more Fifa executive committee members were paid nearly £1m to vote for Qatar's
Conservative MP Damian Collins stated that evidence submitted by the Sunday Times newspaper - which the committee will publish - claimed that Fifa vice-president Issa Hayatou, from Cameroon, and Jacques Anouma, from the Ivory Coast, were involved.
Fifa's ethics committee last year banned two other executive committee members after a Sunday Times investigation into World Cup bidding.
Triesman told a Department of Culture, Media and Sport committee that - with hindsight - his bid team should have reported the quartet he made claims against immediately.
Speaking at the House of Commons on Tuesday, Triesman said that he will now take his evidence to world governing body Fifa.
But he insisted his findings would, at least initially, fall on deaf ears.
Triesman said the FA chose not to complain at the time for fear of jeopardising England's bid, which ended up collecting only two out of 22 votes as Russia landed the tournament in December last year.
"I think, in retrospect, we would have burned off our chances," he said. "In retrospect, that was not the right view to take and I accept that."
John Whittingdale, chairman of the Department of Culture, Media and Sport committee, said he would be writing to Fifa president Sepp Blatter to launch an investigation into the evidence "as a matter of urgency".
Blatter himself promised immediate action if evidence of wrongdoing by executive committee members was revealed.
"I was shocked [upon hearing] but one has to see the evidence," said the 75-year-old Swiss on Tuesday, adding that the accused executive committee members were not elected by the same congress as him.
I was working at the highest level of that bid and talking at length with the chairman and ceo and saw no evidence of any of these allegations.

"They are coming from other confederations, so I cannot say that they are all angels or all devils.
"There is a new round of information. Give us time to digest that and start the investigation by asking for evidence on what has been said.
"We will react immediately against all those in breach of the ethics code rules.
"Zero tolerance is going through Fifa, it is one of the items on the Congress. It is my battle horse."
Fifa secretary-general Jerome Valcke claimed the governing body had been very clear about what was considered ethical behaviour during World Cup voting.
"We will be asking for evidence or any information," he said. "We sent a letter to all ExCo [executive committee] members on what they can or cannot do so we were very clear from day one."
Triesman's specific claims are:
- Fifa vice-president Warner asked for around £2.5m to build an education centre in Trinidad, with the cash to be channelled 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;
- Paraguay's Fifa member Leoz asked for a knighthood;
- Brazil's Fifa member Teixeira asked him [Triesman] to "come and tell me what you have got for me", with the implication being that he wanted something in return for his vote;
- Thailand's Fifa member Makudi wanted to be given the TV rights to a friendly between England and the Thai national team.
Triesman also claimed that Premier League chief executive Richard Scudamore offered to support the England 2018 World Cup bid in return for the FA's backing for his controversial '39th Game ' proposal.
MP Damian Collins said the Sunday Times submission regarding the 2022 World Cup vote claimed Qatar specifically employed a fixer to arrange deals with African members for their votes.
Mike Lee, the London-based public relations consultant who worked on Qatar's bid, said he was unaware of any payments being made.

MP urges Fifa to investigate Triesman claims
Lee, formerly communications director of the Premier League, Uefa and London's 2012 Olympic bid, told MPs: "I was working at the highest level of that bid and talking at length with the chairman and ceo and saw no evidence of any of these allegations.
"My experience is I would have had a sense if such things were going on and I had no sense of that."
Two other executive committee members, Amos Adamu from Nigeria and Reynald Temarii from Tahiti, were banned by Fifa's ethics committee last year.
The latest twist means eight executive committee members, one third of the total 24, have either been alleged to have been already found guilty of impropriety in relation to the 2018 and 2022 bids.
