Ordered by the Prime Minister after the phone-hacking scandal, mostly centred on News International and the News of the World, it is intended to shine a light on some of the underhand and illegal practices used by certain sections of the media.
However, politicians have soon found themselves under equal, if not more, scrutiny over their relationships with certain news organisations. During their evidence – intentionally or not –, the Murdochs managed to make their own claims, or revelations, that have turned attention to the motives and integrity of senior politicians.
This week it was First Minister Alex Salmond's appearance before Lord Leveson, amid claims he had offered to lobby on behalf of News Corporation to take over BSkyB.
Labour has claimed he offered to do so in return for the support of the Scottish Sun, while Mr Salmond said his priority was Scottish BSkyB jobs.
Nothing new on that score has emerged and Scottish Labour leader Johann Lamont decided to ask him again yesterday how many jobs were involved and whether they were now at risk because the deal fell through. Mr Salmond stuck to his script and didn't give the answers Labour hoped.
While many may suspect the motivation was political, there is no proof to refute the statement that he was prepared to intervene to save Scottish jobs. Labour may be furious and frustrated but they can't nail the First Minister on this. To do so, they would need to come up with hard evidence. Otherwise it is simply assertion.
A CROSS-party Monty Python Appreciation Group might be on the cards.
After Green leader Patrick Harvie used the Life Of Brian to mock Donald Trump, Alex Salmond quoted the famous 'dead parrot' sketch to put down Ruth Davidson, who had suggested the SNP wanted to keep the Financial Services Authority to regulate banks after independence: "It is no more. It's a dead Financial Services Authority. It's fallen off its perch," Mr Salmond gleefully pointed out.
Laughter all around, except from Ruth. Maybe she's not a fan of the Pythons.
WHEN LibDem Leader Willie Rennie rose to ask a question of Mr Salmond yesterday, he was heckled by several SNP backbenchers even before the subject became clear.
It was childish and disrespectful but sadly not uncharacteristic.
Some people need to learn to behave...
