Former Daily Mirror editor Piers Morgan was interviewed under caution in connection with phone hacking at the end of last year, it has emerged.
The ITV and CNN broadcaster revealed he had been questioned by officers from Operation Golding in early December. Though not naming Morgan directly, Scotland Yard confirmed a 48-year old journalist was voluntarily interviewed at a south London station.
He told the Guardian he was asked to attend an interview in early November in addition to "a full witness statement" he had "already freely provided".
It is believed the discussion surrounded allegations of hacking at the Daily Mirror, which Morgan edited until 2004.
Operation Golding is the Mirror Group equivalent of Operation Weeting, which has been looking into hacking at the News of the World.
Morgan has always denied any involvement in phone hacking and gave evidence to the Leveson inquiry in 2011. Though Jeremy Paxman told the inquiry that Morgan had told him he knew how to hack a phone at a lunch held at the Mirror's offices in 2002.
The Mirror Group became involved in the hacking investigation in March last year when four of its journalists were arrested under Operation Weeting, the allegations focus on the Sunday Mirror in 2003-2004.
Currently former News of the World editors Rebekah Brooks and Andy Coulson are on trial along with five others charged with allegations which include hacking. The Drum has been following the trail since late last year.
