The credit crunch has broken the bank at some of Britain's biggest casinos. In the last 12 months, nine gambling dens have closed their doors - victims of government tax increases, the smoking ban and the worsening economic climate. Gala Coral, owned by private equity firms Permira, Candover and Cinven, has shut four casinos, including its upmarket haunt in London's Picadilly Circus. Genting Stanley has shut two in Liverpool and Manchester and axed 400 staff. It is currently in a pay dispute with the GMB union.
