"I was clearly told that declaring Mr Mutko ineligible would probably cost the presidency because the World Cup would be a disaster and as a outcome the presidency would be put under question", Maduro added.
"I think that, ultimately, he chose to politically survive".
"We were interested with the application of the rules, independently of the persons in question".
The governance committee's decision to bar Mutko, made in March this year, was the key confrontation, Maduro said, in his short tenure as governance committee chair.
Federation Internationale de Football Association has accused former official Miguel Maduro of making "factually incorrect" allegations about their attempts to interfere with his work.
Maduro insisted banning Mutko was the right call and was "very clear" that the Governance Committee were following FIFA's rules. His evidence could throw a fresh spotlight on FIFA President Gianni Infantino's leadership of soccer.
He said Federation Internationale de Football Association president Gianni Infantino "realised that if he wanted to survive politically, he had to choose to protect the independence of bodies, and therefore to keep us in place, or answer to his constituency". The committee was implementing Fifa's own rule that it must be politically neutral and that national associations remain free from government interference. "The problem is that it - opposition to independent scrutiny - is so deeply embedded in their culture that in practice they do not accept the consequences of reform".
Hans-Joachim Eckert and Cornel Borbély, heads ofthe Adjudicatory and Investigatory Chambers of the FIFA Ethics Committee respectively, were also dismissed from their roles.
This comes despite the fact that Tomaž Vesel, from Slovenia, was the only chairman of the five Independent Committees to retain his position for another four-year term.
Maduro will be protected by parliamentary privilege, providing legal protections to speak freely.
"FIFA has noted the comments, interpretations and opinions made by Mr Miguel Maduro at the Digital, Culture, Media and Sport Committee of the House of Commons", it began in a statement.
"Today, the people in charge of FIFA's different committees bear even more of a responsibility to bring about reform then those who preceded them". "The independence of FIFA's committees and the success of FIFA's reform process will only be measured by the decisions taken in the future and not by personal opinions".
