Investigation into Conor Benn's failed drugs tests is held up over a 'lack of cooperation' with UKAD

An investigation into Conor Benns two failed drugs tests has been held up amid claims of a lack of cooperation from the boxers team.

Benns case is being scrutinised by both the WBC rankings body and a separate probe led by UK Anti-Doping and the British Boxing Board of Control over the positive tests that crashed his October fight with Chris Eubank Jr, as revealed by Sportsmail.

While Benns side last month submitted a 270-page dossier to the WBC enquiry, whose remit is seemingly limited to determining if the fighter can return to his place at No 5 in their welterweight standings, Sportsmail understands less cooperation may have been forthcoming for the more meaningful UKAD and Board of Control investigation that will ascertain if he faces a doping ban in this country.

That includes Benns team not handing over the same dossier despite sources claiming a request had been made by the Board of Control. When asked by Sportsmail if it had been shared with their investigation, Board general secretary Robert Smith confirmed it had not, but declined to comment further. UKAD, who as a matter of policy do not confirm if they are engaged in a particular investigation, also declined to comment.
