Premier League club West Ham have reached an agreement to increase the capacity of their London Stadium.
The number of tickets available to be sold for West Ham home matches has been capped at 57,000 since they moved to the host venue for the London 2012 Olympic games in 2016.
A deal with stadium operator E20 has increased that number to 60,000, with further scope to eventually fill the 66,000-seater arena.
That further expansion would give West Ham the second-biggest home ground in the Premier League behind Manchester United.
A statement from the club acknowledged the increased capacity would make London Stadium a more attractive proposition for potential naming rights partners.
"West Ham United and its landlord E20 have agreed a plan which allows the club to sell additional seats for their matches, thereby ending the litigation surrounding the capacity at the London Stadium," the statement read.
West Ham have confirmed plans to install two new tiers of seats closer to their London Stadium pitch in time for the 2020-21 season.
Hammers fans have been critical of the seating arrangement at their home ground, claiming it detracts from the atmosphere on matchdays.
A statement on West Ham‘s official website said: “Following consultation with the Official Supporters Board (OSB) to help inform the brief and an extensive process between the club and (stadium owners) E20, Arena Events Group has been appointed to develop the new seating system.
“Arena will deliver two new lower tier stands bringing fans closer to the pitch, many by more than four metres, with the stand being squared-off in line with a more traditional football stadium configuration behind the goals.
“Following a period of design development, E20 and West Ham United will review the stands with the aim of installing the seats this summer.”
London Stadium was built for the 2012 Olympics and after being converted into a football ground at a reported cost of £323million, West Ham became tenants in August 2016.
Many Hammers fans were reluctant to leave their previous home at Upton Park and have been critical of the matchday experience at the London Stadium.
Supporters have claimed that as well as the distance between the seats and the pitch being too big, transport links to the stadium, plus both toilet and catering facilities in some areas are unsatisfactory.
