A leading boxing promoter has described Daniel Kinahan as 'an honourable man'.
Bob Arum, who has managed the likes of Muhammed Ali, has praised Mr Kinahan for securing the fight between Tyson Fury and Anthony Joshua.
Daniel Kinahan was named by the High Court as a senior figure in the Kinahan organised crime gang - which operates on a global scale.
But Mr Arum dismissed the allegations on Newstalk Breakfast, saying he only judges him for his interactions in boxing.
"Those are allegations and I don't know anything about that, and his dealings with us have been solely about Tyson Fury and the sport of boxing.
"And if anybody asks me, I would say without any question, that I find him to be an honourable man".
"Whatever the other allegations are and so forth - whether they're true or not true - I can't get into, and I'm not going to get into, because it's none of my business".
"He has developed a great deal of trust with my company, myself and our people.
"He certainly is a trusted confident of Tyson Fury - so obviously his participation and his views were most significant and most important in getting this off the ground."
On Daniel Kinahan, Mr Mrum said: "Not only he is intelligent... but he is dead honest and forthright and he's a no-nonsense guy.
"You don't waste a lot of time beating around the bush with him.
"Everything that he has told us and every promise that he's made to us, he's more than fulfilled - and I think he would say the same thing about us".
Asked about any concerns about Mr Kinahan's past and being named in the courts, he said: "I'm not naive - what did or didn't happen prior to his involvement in boxing is not of a major concern to me.
"First of all they're allegations, and secondly they don't really speak to how he has acted when he has been involved in boxing - which is forthright, honest, reliable, etc."
"In boxing, you might remind your prime minister, we've had situations where we've had athletes who were accused and convicted of major crimes serve their time and came into the sport of boxing and not only performed well but excelled, like Bernard Hopkins".
"Boxing has been used by many people who've had questionable backgrounds - if they come in to box, if they conduct themselves well - yes they then achieve a new type of attitude that people have to them because they're nothing but forthright and honest."
