Anthony Joshua won the IBF heavyweight title with a stunning second round stoppage of Charles Martin.
Joshua extended his perfect record to 16 straight knockouts to add the American's IBF belt to his Olympic crown.
The 26-year-old joins Tyson Fury as Britain's second heavyweight champion and could face the Mancunian in a unification fight later this year, providing he wins his re-match with Wladimir Klitschko.
