Until today, Labour had largely avoided raising the allegations of phone hacking against Piers Morgan, who, as editor of the Daily Mirror, was one of the party's biggest cheerleaders on Fleet Street. But that's all changed this morning with the intervention of Harriet Harman. Following Heather Mills's claim  that a senior Mirror Group journalist admitted hacking voicemails left for her by Paul McCartney, the party's deputy leader has said:
It's not good enough for Piers Morgan just to say he's always stayed within the law. There are questions about what happened with Heather Mills' phone messages that he needs to answer. The public rightly expects that we will get to the bottom of phone hacking. That's why it is so important that the police investigation looks at all the evidence and leaves no stone unturned. And it is why we insisted on a full police investigation and the judicial inquiry having the powers and broad remit to get to the bottom of illegal practices in our media.
The questions, in this case, revolve around the fact that the message Mills referred to appears to be identical to that Morgan later admitted listening to. "At one stage I was played a tape of a message Paul had left for Heather on her mobile phone," he wrote in a 2006 article for the Daily Mail . He added: "It was heartbreaking. The couple had clearly had a tiff, Heather had fled to India, and Paul was pleading with her to come back. He sounded lonely, miserable and desperate, and even sang We Can Work It Out into the answerphone."
As a result, there is growing pressure on the CNN host to return from the US and face questioning by Parliament. Tory MP Therese Coffey told Newsnight last night: "I just hope that the police take the evidence and go with it and if Mr Morgan wants to come back to the UK and help them with their inquiries, and I don't mean being arrested in any way, I'm sure he can add more light... I think it would help everybody, including himself and this investigation, if he was able to say more about why he wrote what he did in 2006." But culture select committee chairman John Whittingdale, who is focused on whether MPs were misled by James Murdoch, has said the committee has no plans to summon Morgan.
Morgan has already attempted to dismiss Mills as an unreliable witness, highlighting the fact that a judge branded her "inconsistent and inaccurate"during her divorce from McCartney. But with Rio Ferdinand and Ulrika Jonsson also alleging that their phones were hacked by the Mirror Group, Mills is far from the only foe he faces.
