Calzaghe picked up his CBE in November of last year.

With him at Buckingham Palace were his mum Jackie, dad Enzo and girlfriend Jo-Emma Lavin.

"I had a long think with my family," he told BBC Sport on Thursday. "My children wanted me to give up, plus my mum. That's why I called it a day and will go on to do something else."

Calzaghe, who has two sons, Connor and Joe, from his marriage to Mandy, says he now plans to concentrate on his charity work and becoming a boxing promoter.
