M’learned co-conspirator has drawn Guido’s attention to this ruling by Lord Justice Leveson issued on Thursday and overlooked in the Borisfest:

It has happened that a core participant who is a politician has used material from the disclosed evidence (which was, in fact, later corrected) publicly to challenge the Prime Minister; an apology has been received by the Inquiry for what was, in that case, a total disregard of the terms of the confidentiality agreement but even if the question had been withheld until the statement was published, there was almost no time for the information (wrong, as it turned out to be) to be checked and the question dealt with.

Chris Bryant used a Point of Order to accuse the PM of lying to the house about meetings with Murdoch. As Leveson says in his ruling this was based on erroneous evidence that was uncorrected, unpublished, confidential and yet to be checked and published by the Inquiry. Chris Bryant only had access to the evidence submission by virtue of his status as a Core Participant in the Inquiry. Guido said at the time Bryant would regret it, Baroness Warsi insisted he apologise to Leveson – advice he has clearly accepted – and that the Parliamentary Standards Commissioner should reprimand him – which remains to be seen.

As government figures prepare to appear before the Inquiry it seems obvious that Bryant should lose his Core Participant status, he is clearly ready to use it for political advantage. He has demonstrated that he simply can’t be trusted to keep his word.
