A host of A-list names from the world of showbiz have signed an open letter to the Prime Minister calling on him to protect the BBC from cuts to its service. James Bond actor Daniel Craig, his colleague in the long-running 007 franchise Dame Judi Dench, and veteran broadcaster David Attenborough are among those to have added their names to the letter. The signatories, including author JK Rowling, comedian Miranda Hart and presenter Chris Evans, have called on David Cameron to ensure the Government does not “turn it into a narrowly focused market-failure broadcaster”.
