Piers Morgan. A member of British Parliament is calling for Piers Morgan to answer questions regarding what he might know about possible phone-hacking that may or may not have taken place under his tenure-ship at the Daily Mirror.

Labour deputy leader Harriet Harman tells Sky News that Morgan "has got to answer" questions and then -- in reference to Heather Mills allegations that she'd been hacked by a Mirror Group reporter who admitted to it -- said Morgan had heard a 'heart-breaking' phone message, which clearly gives rise to the assumption that he'd heard a tape-recorded message."

A couple of things of things to consider. Three weeks in there is zero evidence that Morgan knew or did anything. So far the allegations have been almost entirely the results of Morgan's own words used against him.

Secondly, Heather Mills is not exactly the world's most reliable witness, in so far is notoriously press hungry (in his statement yesterday Morgan says Paul McCartney accused her of leaking his phone messages to the press).

Thirdly, I have no idea who Harriet Harman is but if she's anything like MP Louise Mensch (who misquoted Morgan during Murdoch's hearings and then popped up all over TV to talk about it), or like pretty much any politician that takes to cable news to make their case than there is at least a small chance she is calling for Morgan to answer questions because she wants in on some of the spotlight he will inevitably bring with him.

That's not to say Morgan has nothing to worry about -- for one, he has yet to explain how he heard the McCartney voicemail. But it is to say at some point someone is going to have to produce actual evidence instead of simply inferring what Morgan might have meant when he said something possibly in context with phone-hacking.
