Piers Morgan has confirmed that he was interviewed by officers investigating phone hacking in December.
Metropolitan Police said a 48-year-old journalist was "interviewed under caution", although a spokesman refused to confirm the name of the individual.
In a statement to The Guardian through a spokesperson, Mr Morgan said:
In early November I was asked to attend an interview by officers from Operation Weeting when I was next in the UK.
This was further to a full witness statement I had already freely provided. I attended that interview as requested on 6 December 2013.
Morgan, who is now a presenter on CNN, was editor of the Daily Mirror from 1995 until 2004.
Former Daily Mirror editor Piers Morgan has been questioned under caution about phone hacking, Press Association sources have confirmed.
"A 48-year-old man, a journalist, was interviewed under caution on 6 December 2013 by officers from Operation Golding in connection with suspected conspiracy to intercept telephone voicemails," a Metropolitan Police spokesman told ITV News.
"He was interviewed by appointment at a south London police station. He was not arrested."
Broadcaster Piers Morgan says he has been told by sacked English cricketer Kevin Pietersen that "the issue of trust" was never raised with him between his "rehabilitation and sacking".
Just spoke to @kp24 - nobody has EVER raised the issue of 'trust' with him between rehabilitation & sacking. Not ECB, Cook, anyone. Fact.
ECB not produced a single shred of evidence that @kp24 breached Cook's, or anyone else in team's trust since coming back into side. Fact.
No comment has been made by Pietersen's management since the England and Wales Cricket Board confirmed the former player had been released from his contract.
Broadcaster Piers Morgan claims that his friend Kevin Pietersen has not been selected for the upcoming one day tour of West Indies and the World Twenty20 next month.
The former Daily Mirror editor was highly critical of the ECB's decision:
I can confirm Kevin Pietersen has been SACKED by the pathetic, spineless losers at the @ecb . Unbelievable.
KP sacked for being England's highest run-scorer in all competitions, and highest run-scorer in Ashes debacle. SHAMEFUL. #KPSacked

Broadcaster Piers Morgan was also subjected to abusive tweets after he joined calls for police and Twitter to take action over the abusive messages aimed at Collymore.
The former tabloid editor tweeted:
I repeat, racist abuse & death threats both criminal offences in UK. So keep spewing it, trolls, and I will have you ALL dealt with.
Piers Morgan has blasted rivals Graham Norton and Jonathan Ross' interview skills, saying only he could interview people for hours at a time.
The former Daily Mirror editor, known for making his guests cry on ITV show Life Stories, rated retired host Michael Parkinson for being able to switch between comedy and interview.
Morgan boasted: "I'm the only person who sits down with people on TV for two or three hours to truncate to a one-hour show. So I think I'm almost in a category of my own."
The 48-year-old told the Radio Times: "I can't compete with Graham Norton for the comedy he brings and I think he's got a terrific show. Or Jonathan Ross. Or Alan Carr. They're all entertainers and comedians, really.
"They're not any of them particularly great interviewers. I don't think they profess to be. Parky could do both."
Coronation Street legend Julie Goodyear said she regrets her short-lived return to the soap to revive Bet Lynch because it was like being on "a conveyor belt".
The 71-year-old returned to the show in 2002, but lasted little over a fortnight because she struggled to cope with the changes in the workload.
In an interview for Piers Morgan's Life Stories, Goodyear claimed she had not been informed about how the demands of filming had altered since she had left the show seven years earlier.
The actress said: "When I walked in, it was like being on a conveyor belt. We'd always had rehearsal. We'd always had make-up and costume and everything. I had about 27 Rovers scenes and we started at the end."
Piers Morgan's Life Stories: Julie Goodyear is on ITV tonight at 9pm.
