Strictly Come Dancing star Joe Calzaghe has apologised to fans after admitting occasional cocaine use, following allegations in the Sunday papers.

The former world middleweight and light-heavyweight boxer said he had taken the drug during “what have sometimes been the long days” since he retired.

It follows a News Of The World sting in which he discussed buying and taking cocaine with an undercover reporter.

The paper reported that during its meeting with the boxer, the subject turned to the drug.

“I very much regret my occasional use of cocaine in what have sometimes been the long days since my retirement from the ring,” Joe said in a statement on his website.

“I am fully aware of the bad example it sets to other people and particularly to youngsters and I apologise to my family, friends and fans.

“It is not a major problem in my life but it is something I am actively addressing.”

Joe hit the headlines when he appeared in the 2009 series of Strictly Come Dancing, after he struck up a romance with his dance partner Kristina Rihanoff.

The pair were voted off the series in week five.
