Parliamentary Voting System and Constituencies Bill

Does my hon. Friend not appreciate the concern that when we are discussing whether there should be any variance, be it of 5% or 7.5%, it is important to know how the process operates? If the entire United Kingdom—its 650 seats—was to be considered at once, there would be almost no need for any variance. If things are considered on the basis of smaller clusters, one can see the relevance of having that sort of variance, particularly if there is also a desire to avoid crossing ward boundaries. We do need to have an understanding of the process. If we do not have at least a basic understanding of how it will operate, it will be difficult for us to make any value judgment as to where the variance should lie, which is the subject of amendment 19.
