Olympic gold medallist Anthony Joshua has left his place in the Great Britain amateur boxing programme in order to turn professional.
The 23-year-old, who defeated Roberto Cammarelle in the super-heavyweight final at London 2012 last summer, will sign for the Matchroom organisation fronted by promoter Eddie Hearn.
Great Britain performance director Rob McCracken said: "Anthony is a very talented sportsman who has enjoyed a meteoric rise to become Olympic champion, less than four years after he first began boxing.
"Naturally, it is a disappointment for us that Anthony has decided his future lies away from the GB Boxing programme, but he departs with our very best regards and we wish him every success in his future career."
Joshua could made his debut on the undercard of the bout between Carl Froch and George Groves later this year.
