As an amateur he represented Britain at the 2012 Olympics, winning a gold medal in the super-heavyweight division.
In 2017 Anthony fought Wladimir Klitschko at Wembley Stadium. Watched by 90,000 at the sold-out venue and broadcast around the world, the fight went down as one of the biggest in boxing history with Anthony emerging victorious.
As of June 2017, Joshua is ranked number 1 heavyweight by BoxRec, Transnational Boxing Rankings Board and by The Ring magazine.
Joshua is the second British boxer, after James DeGale, to win both a gold medal at the Olympics and a world title by a major professional sanctioning body, as well as being the first British heavyweight to do so.
He is also the second boxer, after Joe Frazier, to win a world heavyweight title whilst still reigning as Olympic champion at the top weight.
