THE trial of David Cameron’s former spin doctor Andy Coulson continued yesterday as the court was told how the one-time News of the World editor knew that the source of voicemail messages was from phone hacking.

Mr Coulson is back in court after being accused of lying under oath in 2010, during the perjury trial of former socialist MSP Tommy Sheridan.

News of the World chief reporter Neville Thurlbeck told Edinburgh High Court how Mr Coulson knew that the paper’s coverage of the Milly Dowler murder used hacked messages.
