Big fight:Tyson Fury versus Athony Joshua is on.

It was the Gypsy King himself who revealed it all in a near joyous social media post last June.

“I’m just after getting off the phone with Daniel Kinahan. He’s just informed me that the biggest fight in British boxing history has just been agreed. Get in there my boy!”

The big fight was on. Terms had been agreed for the contest boxing fans wanted more than any other – Tyson Fury versus Anthony Joshua.

Fury’s post was exultant. “Big thank you Dan for getting this deal over the line.”

For British fight fans, it couldn’t have been better news. The two best heavyweight boxers in the world would fight it out to be the undisputed world champion. Boxing loves hype but it is almost impossible to overstate the significance of this contest.

When it happens, it will be the biggest and most moneyed fight in British boxing history. Hundreds of millions of pounds will be in the mix for the fighters, promoters and broadcasters. And at the end of it, one of two British boxers will stand on top of the world, holding the belts once hoisted high by the likes of Muhammad Ali and George Foreman.

But Tyson Fury hadn’t just given boxing fans the news they wanted to hear. He had also given up one of boxing’s darkest secrets. The man he thanked three times in his 55-second video, is alleged to be one of Europe’s top mobsters, whose cartel deals in drugs, guns and murder.

That’s Tyson Fury’s adviser Daniel Kinahan.
