Lord Justice Leveson has warned politicians not to disclose information on the contact between Jeremy Hunt and News Corporation before evidence has been heard before his inquiry.Speaking today, the judge said ministers discussing evidence in the House of Commons before the Culture Secretary and others have appeared before him could “undermine the fairness of the procedure".He also said he would not adjudicate on whether the House had been mislead by Hunt, saying it was up to the Prime Minister “to take any action he wishes in connection with the conduct of one of his ministers.”Emails between News Corp’s Frederic Michel and Hunt’s office, submitted to the inquiry, imply Hunt may have had inappropriate contact with Rupert Murdoch’s company over the BSkyB bid.Leveson said he would call Michel and Adam Smith, Hunt’s special advisor, before the end of May. It is likely Hunt will also appear this month.He noted the emails had been the subject of “immediate comment” in Parliament and the media, and said if evidence is disclosed early he would consider not questioning Hunt, Michel and Smith over the bid.He said: “If the evidence were to have been forced into the public domain and be the subject of argument and debate in advance of the witness giving evidence so that minds are potentially made up and conclusions reached, my immediate reaction would be that I would consider it unfair to subject the witnesses to further questions before this inquiry.”“I would hope sufficient respect for my process will allow it to proceed without interruption and without effectively rendering the order which I have made entirely academic.”Yesterday Harriet Harman MP asked whether Hunt was still accountable and subject to questions from other MPs while waiting to appear at the inquiry.Speaker Bercow replied: “As a matter of general principle, I should make it clear that the accountability of a minister to this House is not diluted or suspended by a minister's engagement with inquiries or other proceedings outside of this House. When Parliamentary Questions to ministers are tabled, those questions should receive substantive and timely answers.”Leveson told the inquiry he was not taking sides but it was important to hear every side of the story before drawing conclusions.He added: “I am approaching my task in a politically neutral fashion and intend to ensure that the principles of fairness which I have sought to maintain throughout apply equally to this module. I will be considering the way in which politicians of all parties have engaged with the press.”"I hope that allowing the inquiry to proceed as it plans will not amount to a serious inconvenience either to Parliament or to the political process generally. On the contrary, I hope that the process which I have put in place is well placed to assist both."
