Parliamentary Voting System and Constituencies Bill

My hon. Friend makes a good point. There is no reason why the census should not be able to engage in that activity. If people are going door to door, they could be doing more than one task. In addition, there will be profound embarrassment if, according to the census, the number of people eligible to register in Liverpool, Manchester or Birmingham, or wherever else, turns out to be considerably higher than the number of people who are registered, and yet constituencies have still been allocated solely on the basis of those who are registered.
