London: FIFA chief Sepp Blatter vowed to address fresh allegations of corruption against football's governing body on Tuesday.
In comments reported by Sky Sports television, Blatter said he could not be held responsible for the conduct of individual members.
"If this is true, I will fight this," Blatter was quoted by Sky as saying.
"I am fighting for FIFA to clean FIFA."
"I cannot answer for individual members of our committee. I cannot say if they are all angels or if they are all devils."
British members of parliament have said they would contact Blatter demanding an investigation into the latest evidence "as a matter of urgency."
It came after the parliamentary committee heard evidence alleging six members of FIFA's executive committee had sought cash or honours ahead of the votes to decide the 2018 and 2022 World Cups.
Jack Warner, the influential head of the North and Central American federation CONCACAF, dismissed evidence given by former England 2018 bid chairman David Triesman as "a piece of nonsense."
"No doubt he feels he can revive his dying political career by mentioning that piece of foolishness," Warner was quoted as saying by Sky.
"I've never asked Triesman nor any other person, Englishman or otherwise, for any money for my vote at any time."
