Parliamentary Voting System and Constituencies Bill

The crux of my hon. Friend's argument is the instability that will be caused by the five-yearly boundary reviews. Does he feel that an opportunity was missed in Committee when the House rejected an amendment tabled by the hon. Member for Leeds North West (Greg Mulholland) that would have established reviews every 10 years? That would have brought greater stability for mainland Members who, rather than looking over their shoulder every five years, would have had some breathing space and a continuous constituency for at least one Parliament. Does my hon. Friend agree that, unfortunately, the other place might have to ride to the rescue of the Commons yet again?
