Andy Coulson told the Old Bailey hacking trial he made the decision not to "help or hinder" a 2006 police investigation into hacking at the now-defunct News of the World.
"I made my decision, and I decided that I wouldn’t hinder the police investigation, but I made the decision I wouldn’t help the police investigation," the paper's former editor said in response to a question by co-defendant Clive Goodman's lawyer, David Spens QC.
Mr Coulson also accused the ex-royal editor of "completely twisting" his words after a meeting at a cafe in Wimbledon, south west London, in which Mr Goodman alleges his boss tried to convince him to admit he undertook hacking a "lone wolf".
