The Dome itself is to be turned into a 20,000-seat auditorium for sports events and concerts. One of MDL's backers is Phil Anschultz, the billionaire American developer known for building successful sports arenas. The rest of the site is to be developed gradually as pockets of land are sold off for commercial and housing developments. The amount of money which eventually comes back to the taxpayer has always been uncertain, once Tony Blair rejected the possibility of knocking down the Dome and selling off the site for a much greater sum.
