Former boxing promoter Mickey Duff has died at the age of 84.
Born Monek Prager in Poland, Duff moved to England in the late 1930s.
The son of a rabbi, he had a brief career in the ring as an amateur, then professional.
However, he retired from the action at the age of 19 before becoming a promoter and it was unquestionably outside the ring where he made his name, as a matchmaker and manager.
Duff was involved with 16 world champions, most of the best British fighters of their generation, including Frank Bruno, Joe Calzaghe, Alan Minter, John Conteh, Terry Downes, Lloyd Honeyghan and Jim Watt.
He retired from the sport in 1999 and, in the same year, was inducted into the International Boxing Hall of Fame.
Fellow promoter Barry Hearn led the tributes, tweeting: "Sorry to hear that Mickey Duff died today RIP Legendary promoter."
A statement from Stephen Powell on the London Ex Boxers' Association website added: "The London Ex Boxers Association offer their heartfelt condolences to the family of Mickey Duff, who very sadly passed away peacefully in his sleep early this morning.
"This truly is the end of a golden era in British Boxing, the mould has been broken, there will never be another "true boxing man" like Mickey Duff."
