West Ham United has confirmed that the working capacity of its new London Stadium for the English Premier League football club’s game against Bournemouth on Sunday will be 57,000.

The fixture will mark West Ham’s first-ever league game at the ground, which served as the centrepiece for London’s staging of the 2012 summer Olympic Games.

The capacity had originally been set at 54,000 for this weekend’s game but that has now been increased following a meeting of the London Stadium Safety Advisory Group (LSSAG). Newham Council formally agreed to the increase.

The club also reiterated its stance on supporters standing throughout games. Last week, vice-chairman Karren Brady penned an open letter to fans, urging them to remain seated during matches so as not to restrict the views of those around them.

West Ham said the LSSAG has “identified that standing in an all-seater stadium is dangerous and contrary to ground regulations”. The LSSAG will continue to monitor the situation.

West Ham confirmed it would continue to work with Newham Council, the LSSAG and other relevant bodies to ensure London Stadium is able to operate at its intended capacity of 60,000 as soon as possible.

The club has so far played two games at London Stadium – the Uefa Europa League match against Slovenian side NK Domzale on August 4 and the friendly game against Italian Serie A team Juventus on August 7. The ground operated at a capacity of around 54,000 for both fixtures.
