The full extent of the toxic relationship between West Ham United and their London Stadium landlords can be laid bare today with The Daily Telegraph able to reveal that the two sides are locked in a £100 million-plus legal row that will see them face off at the High Court in November.

West Ham and the publicly-funded London Legacy Development Corporation (LLDC) spent Monday in talks over how to prevent a repeat of Saturday's violent protests during Saturday’s game with Burnley, but the two sides are also in a bitter dispute over the capacity for football matches at the former Olympic Stadium.

When West Ham moved in to the stadium last season under the "deal of the century", they believed it would entitle them to a capacity of 60,000, but LLDC said the figure was just 53,500. A compromise was reached that guaranteed West Ham an additional 3,500 seats.

However, West Ham want permission to fill all of the stadium's 66,000 seats, which could be worth millions of pounds each year to them in increased ticket revenue. With LLDC demanding payment for anything above 57,000, the club has brought the lawsuit against the authority.

The legal dispute is a new low in the complex relationship between the two sides since West Ham became tenants at the Olympic Stadium for an annual fee of £2.5m. There were serious security issues during last season’s Carabao Cup tie with Chelsea and West Ham have now demanded both an increased police presence and that they are allowed to take over stewarding after the shocking events of Saturday, where there were repeated pitch invasions and fans hurled abuse and coins at co-owners David Sullivan and David Gold.
