Call For PM To Act On Tax Havens After Leak

David Cameron has been urged to take "real action" against offshore tax havens after a huge data leak revealed details about UK clients of a Panama-based law firm. The PM's late stockbroker father, Ian, is also reported to be identified in more than 11 million files leaked from the database of Mossack Fonseca, the world's fourth biggest offshore law firm. There is no suggestion that any of those named in the so-called 'Panama Papers' have done anything illegal.
