The chair of the corporation which owns London's Olympic Stadium has resigned after London Mayor Sadiq Khan announced an investigation into the cost of converting the arena for football.
David Edmonds announced his resignation as chair of the London Legacy Development Corporation two days after Mr Khan demanded an inquiry, in light of new figures which reveal that the conversion cost has jumped from £272 million to £323 million.
The venue was renamed the London Stadium over the summer and now hosts Premier League side West Ham United. However the deal agreed by West Ham and the LLDC attracted a firestorm of criticism after it was revealed that the football club will pay a basic rent of just £2.5 million a year on the stadium, and have committed just £15 million to its conversion.
West Ham's move to the stadium, which was built for the 2012 London Olympics, has also been blighted by repeated outbreaks of violence between supporters at the club's home matches. The most recent outbreak took place at West Ham's EFL Cup match with Chelsea, with one witness comparing the chaos to the Hillsborugh disaster.
