Prince Naseem - who stands at only 5 ft 4 and weighed less than 10 stone in his hey-day - was also renowned for somersaulting his way into the ring.

He became Britain's youngest world champion in 1995 aged just 21, winning 36 of his 37 professional fights, losing only to Marco Antonio Berrera in 2001.

The sportsman first started piling on the pounds after he was involved in a serious car accident in 2006.

He was jailed for causing the 90-mph three-car collision, in which another driver suffered fractures to every major bone in his body.

The star left prison after 16 weeks looking noticeably bigger.

Following his retirement from the sport he oversees a management company with offices in LA and London.
