A record 90,000 fans will pack Wembley Stadium to watch the heavyweight clash between Anthony Joshua and Wladimir Kiltschko.

Mayor of London Sadiq Khan has announced that the eagerly anticipated fight for Joshua’a IBF world title and the vacant WBA Super and IBO straps on April 29 will be seen by a post-war record crowd.

The Mayor held talks with officials from Network Rail, Transport for London and Wembley Stadium to explore ways to increase capacity by committing more overground trains and London Underground services to ferry fans to and from the event safely. There will be an increased service on the Jubilee and Metropolitan lines.

Mr Khan increased capacity for the fight by 10,000 after Matchroom Boxing promoter Eddie Hearn initially secured permission for 80,000.

He said: “I can’t wait to see the fight of the year here in London and it’s fantastic that a post-war record crowd will get to watch it at a world-class venue like Wembley.”

Cllr Muhammed Butt, Leader of Brent Council, also welcomed the news, saying: “Wembley is a world class venue that has hosted many historic sporting and entertainment events over the years and this record attendance for a boxing match will be yet another chapter in its long and glorious history.

“It just goes to show that when it comes to competing with other stadiums in cities around the world to stage the biggest bouts, Wembley Stadium in Brent can deliver the knock-out blow to its rivals, helping to ensure that London remains the number one choice for event organisers and fans alike.

“We have been home to the national stadium for nearly a century and this record-breaking boxing match builds on our international reputation for hosting such cultural and sporting events.”

The London showdown, which will be broadcast around the world, will break the post-war British record for attendance at a boxing match for the rematch between Carl Froch and George Groves at the same venue in 2014 and equal the British record 90,000 crowd who saw Len Harvey fight Jock McAvoy at White City in 1939.

Julie Harrington, FA Group Operations Director, said: “Wembley Stadium is a world-class venue and we are delighted to stage this highly anticipated heavyweight world title fight.

“We look forward to utilising the stadium’s full capacity and welcoming 90,000 people to watch one of the sporting events of the year.”
