Parliamentary Voting System and Constituencies Bill

I did not say that it was the 2000 census; I said it was the 2000 electoral register. The 2000 electoral register is the relevant basis for assessing the electorate. In the same way, the report that the Boundary Commissions will be expected to produce by October 2013 will be based on the electoral register as at 1 December 2010. As I have indicated, because population estimates are produced at the local government level, it would be equally or even more of a problem to estimate the true level of the population at lower than that level. Local government geography is obviously a relevant issue for the Boundary Commission, but it might find that even if population estimates were consistently compiled for areas smaller than the local authority level, the data may not be sufficient to allow it to draw up a constituency boundary that meets the two size requirements as set out in the noble Lord’s amendment. For example, the commission might have to depart from using wards as a building block to reduce the population of a constituency that was slightly over the 130 per cent limit. Furthermore, the amendments are silent on what would happen if the commission found itself unable to comply with both of these rules in an area. The amendments would make the commission’s task vastly more complex and unachievable.
