Anthony Joshua’s heavyweight title fight with Wladimir Klitschko has broken box office records after more than 80,000 tickets were sold for the Wembley event.

The bout, which will take place in April, has now generated greater ticket sales than the previous post-War boxing record set by Carl Froch’s rematch with George Groves at Wembley in 2014.

The second batch of tickets took less than an hour to sell out when they were released on Monday.

Promoter Eddie Hearn said: “The demand for tickets for Anthony Joshua vs Wladimir Klitschko is phenomenal – this is unquestionably the biggest fight in British boxing history and we would have sold out Wembley twice over.”

Hearn said that a request has been put to Brent Council, the Mayor’s office and TFL to increase the capacity by a further 5,000 tickets. This is fewer than the 10,000 mentioned by Hearn last month, and means the Anthony Joshua fight will not match the 90,000 all-time UK record set when Len Harvey fought Jock McAvoy at White City in 1939.

Hearn said: “We are confident of a positive answer and we will release further news shortly. Roll on April 29.”
