Former News of the World editor Andy Coulson was ordering an internal mole hunt and not the hacking of Calum Best’s mobile when he sent an email with the instruction “do his phone”, a court has heard. The Old Bailey today revisited an email between Coulson and former news editor Ian Edmondson which contained the order. However, Coulson was asking Edmondson to check the phone records of News of the World showbiz reporter Rav Singh who was suspected of leaking information to Best - Coulson's defence lawyer claims.
