The chair of the House of Commons Standards and Privileges Committee has said he is "open minded" about the coalition's proposals to introduce a recall procedure for MPs.
Kevin Barron gave evidence to the Political and Constitutional Reform Committee on 26 January 2012, following the publication of a White Paper on giving voters in a parliamentary constituency the opportunity to trigger a by-election.
Under the proposals, a recall petition would be triggered if an MP was deemed guilty of serious wrongdoing.
If at least 10% of constituents sign the petition, the MP's seat would be automatically vacated and a by-election would follow.
However Mr Barron said there was no clear definition of "serious wrongdoing", and said the proposals needed to be made "transparent and easily understood".
A committee of MPs would be given the power to define the range of offences for which recall could apply, with the Standards and Privileges Committee being seen as the potential committee to wield this power.
It is already the case that where an MP is convicted of an offence and receives a custodial sentence of more than 12 months, their seat is automatically vacated and a by-election is held.
Evidence was also taken from:
• John Lyon, Parliamentary Commissioner for Standards
• Robert Rogers, Clerk of the House of Commons
• Liam Laurence Smyth, Clerk of the Journals of the Commons
