Anthony Joshua has beaten Wladimir Klitschko to unify the IBF, IBO and WBA (Super) heavyweight world titles.

The Brit powered past Klitschko, who hadn’t entered the ring for a professional fight since 2015, by 11th-round knockout.

A post-war record crowd of 90,000 were treated to four impressive fights on the undercard before Joshua and Klitschko entered the ring.

The victory means London 2012 gold medal-winning Joshua has now won all 19 of his professional fights, with each coming inside the distance.

The match was billed as a battle between flourishing youth and level-headed experience, and the powerful, long reach of Joshua swung the bout as Klitschko’s lengthy spell away from the ring told.

Going into the fight Joshua had boxed 314 less rounds than Ukrainian Klitschko, who told fans it would be “his night” .

And the super-fight was broadcast in more than 140 countries as Joshua made his opponent swallow those words with several punishing hooks to the jaw.
