BT Sport are reviewing their past dealings in boxing after claims that alleged gangster Daniel Kinahan made millions in consultancy fees from fights involving Tyson Fury.  

Fury's stateside promoter Bob Arum admitted earlier this month that his Top Rank company had paid 'at least a million' in consulting fees to Kinahan for each of the heavyweight champion's fights against Tom Schwarz, Otto Wallin and back-to-back showdowns with Deontay Wilder.

While BT have no commercial link to Arum or Top Rank, Sportsmail understands the broadcaster, which screens Fury's fights in the UK, is now doing increased due diligence on their previous transactions around the boxer. 

Fury and British-based promoter Frank Warren of Queensbury have maintained they had no knowledge or involvement in any payments from Arum to Kinahan and there is no suggestion of wrongdoing by either.

In a statement BT Sport said: 'We have always taken allegations of corruption very seriously, and for the last few years have gone even further to be extremely proactive to ensure that we only deal with legitimate and verified businesses in boxing. 

'This is not limited to but includes taking additional specialist legal advice to ensure more stringent and thorough provisions are included in all contracts. (And) agreement with our partner Queensberry Promotions, for a robust process around the strict ways we conduct business.'

The sanctions imposed by the US government against Kinahan have sent a shockwave through the sport, with powerhouse management company, MTK, folding last week. 

It was co-founded by Kinahan and former European champion Matthew Macklin in 2012, before the pair cut ties in 2017.

Macklin has since gone on to become a prominent figure on Sky Sports, but the broadcaster insists he has no remaining business ties to Kinahan. 

In a statement, Sky Sports told Sportsmail: 'Matt Macklin disposed of his stake in MTK in 2017. Since then, he has had no commercial dealings with Daniel Kinahan. Like everyone at Sky Sports, he will fully comply with the US Sanctions.'

When asked about Arum's comments, Sky Sports, which has an output deal with the 90-year-old's Top Rank company, said in a statement: 'The payment in question is for fights which Sky Sports had no involvement with and were not screened on Sky. 

'Top Rank has confirmed that it has not made any payments to any of the sanctioned companies or individuals for fights broadcast by Sky Sports.'

There is no suggestion of any wrongdoing or involvement by Fury and the heavyweight champion's team insist he cut ties with Kinahan in 2020.
