MPs rapped by sleaze watchdog for not agreeing tighter controls on lobbying However, the changes have yet to be debated and voted on by the Commons. Motions on conduct have previously been taken in government time, and tabled by members of the committee - but it is not clear why nothing has surfaced. Parliament has been hit by a series of high-profile lobbying allegations over recent months, with Tory backbencher Patrick Mercer and Energy and Climate Change Select Committee chairman Tim Yeo both subject to investigations. Ms Hudson said: "I am concerned that the House has not yet considered the revisions to the Guide to the Rules relating to the conduct of Members which were proposed by the Committee on Standards in December 2012. My predecessor and the Committee on Standards and Privileges undertook considerable work to produce an entirely new Guide, which both clarifies and simplifies the expectations on Members. I believe it will support Members in their day to day work if these can be introduced in the near future. Ms Hudson added: "It is more than ten years since the House last substantially revised the rules on lobbying. Since then, the House has considered the case of Members of Parliament approached by undercover reporters purporting to offer employment as lobbyists after those Members had left the House. Some, but not all, of those approached breached the rules of the House. The House approved the report from the Committee on Standards and Privileges, in which the Committee had agreed with my predecessor that there was a strong case for a review of the rules relating to lobbying. The proposed new Guide to the Rules offers the House an opportunity to consider the lobbying rules in the light of widespread public concern about Members' lobbying activities and to take action to improve the situation. Turning to the issue of MPs' private conduct, the commissioner said: "I hope the House will also soon have a chance to reconsider its decision to prevent the Commissioner from investigating the conduct of any Member in his or her private and personal lives, when that conduct has significantly damaged the reputation and integrity of the House or its Members generally. Such conduct is rare and the Committee offered an additional safeguard to prevent unwarranted intrusion into Members' lives by recommending that the Commissioner should only undertake such an investigation with the Committee's agreement. If the House accepts this change, it will bring clarity to the rules in this area and to my remit.
