Sir Paul McCartney said he would be in contact with the police over his ex-wife’s allegations that a senior Trinity Mirror Group reporter hacked a voicemail he had left for her.

Mills claimed on BBC’s Newsnight that in 2001 the reporter repeated “verbatim” a message that her then boyfriend McCartney had left for her while she was in India.

She says when she then accused the reporter of hacking her phone to get the message he admitted as much and backed down about running a story.

"I will be talking to them about that," McCartney said of his plans to meet with police.??"I don't think it's great. I do think it is a horrendous violation of privacy, and I do think it's been going on a long time, and I do think more people than we know knew about it. But I think I should just listen and hear what the facts are before I comment," he said.

Mills and McCartney were married in 2002 and divorced six years later.

The revelation piles further pressure on ex Daily Mirror editor Piers Morgan.

Morgan has flatly denied any involvement in phone hacking and said Mills’ claims were “unsubstantiated”.

Both Tory and Labour MPs have called on Morgan, who now has a chat show with CNN, to speak to the police in the light of this new information.

Meanwhile Associated Papers, the publisher of the Daily Mail, Mail on Sunday and the Metro, has announced it is reviewing its editorial controls in light of the ongoing phone hacking scandal..

The media company released a statement saying its head of editorial legal services, Liz Hartley, would be overseeing the review.
