LONDON (AFP) - A journalist told Britain's phone hacking trial on Wednesday that Rupert Murdoch's News of the World tabloid routinely eavesdropped on celebrities' voicemail messages and editor Andy Coulson "knew exactly what was going on".
Reporter Dan Evans, who has pleaded guilty to conspiracy to hack phones, said "even the office cat" knew the illegal practice was widely used at the now defunct paper.
Mr Coulson, a former media chief to Prime Minister David Cameron, stared out from the dock as Mr Evans told the jury at London's Old Bailey court: "The truth is that Andy Coulson knew exactly what was going on on his watch."
Mr Coulson looked up and exchanged stares with Mr Evans, who was giving evidence for a third day as a prosecution witness.
Mr Murdoch closed the News of the World in 2011 over a storm of revelations that its staff had illegally accessed the voicemail messages of a murdered schoolgirl, as well as hundreds of celebrities.
Mr Coulson, 46, and his predecessor as editor Rebekah Brooks are on trial alongside several other former employees of Mr Murdoch's British newspaper wing.
They all deny charges linked to phone-hacking.
Mr Evans told the court on Monday that he was recruited to the News of the World in 2004 from the rival Sunday Mirror because of his hacking skills - and Mr Coulson knew this when he hired him.
The reporter described to the court how he had discovered that James Bond star Daniel Craig was having an affair with the actress Sienna Miller by hacking Mr Craig's phone.
Mr Coulson had described the tape of the conversation as "brilliant", Evans claimed on Tuesday.
But interrogated over this claim by Mr Coulson's lawyer on Wednesday, Mr Evans admitted he may have been "paraphrasing" when he said Mr Coulson had said the tape was "brilliant".
Mr Coulson edited the News of the World from 2003 until 2007, when he became Cameron's communications chief. He was forced to quit in 2011 over claims that he knew more about hacking at the News of the World than he had previously admitted.
