Mike Tyson has "no regrets" about his savage and controversial career.

The former world heavyweight champion is due in Britain next month to talk to fight fans who will pay £25-a-head to hear about his turbulent life.

Tyson, who once infamously bit a chunk out of Evander Holyfield's ear, said: "I don't have any regrets because everything I have done - the good and the bad - catapulted me to become the person I was willing to become and that's one of the greatest fighters that ever lived."

The youngest-ever world heavyweight champion at 20, Tyson served a three-year jail term for rape and filed for bankruptcy in 2003 after having earned £200million in his turbulent career.

He insists he will not make another comeback but told BBC Radio 5 Live's Sportsweek programme: "At that stage of my life I was mean. I was happy to be the person who was savage because all my life I used to hear about these fighters who were savages, monsters and animals. It made them almost inhuman and I loved the stigma behind those guys.

"That's why they continued to live in my head and that's why I wanted to be like them. They motivated me to be the guy that I became at that stage of my life."
