Parliamentary Voting System and Constituencies Bill

My noble friend has made an important point about the importance of considering population. But does he agree that this emphasises yet again the folly of rushing this? In a short space of time we will have the results of the 2011 census—probably around 2013 or 2014. It is absolutely crucial in deciding the validity of going forward on a population basis, but also in ascertaining just how under-registered the British people are. What is the degree of under-registration in different constituencies and different population groups throughout the country? Does this not prove the folly of rushing ahead like this?
