Parliamentary Voting System and Constituencies Bill

My Lords, my noble and learned friend, as the House has come to expect of him, has laid out all the relevant issues with magisterial authority. However, I suggest that there is one issue that he may have overlooked, which is that the population of this country is projected to grow very rapidly in the next few decades. If we fix the number of constituencies at 600, or even at 650, we will shortly find that the average number of constituents is unmanageably large. My noble friend Lady McDonagh made an interesting and thoughtful speech on the subject in Committee. We will quickly find ourselves with constituencies of 100,000 voters, trending upwards. Something has to give. You cannot have a fixed quota and a fixed number of constituencies. If the fixed number of constituencies is to be the paramount consideration, the quota will have to jump up at frequent intervals. That is unsatisfactory. That leads me to my second point, on which I slightly take issue with my noble and learned friend. I question whether it is appropriate for the Government to invite Parliament to determine the precise number of Members that there should be in the House of Commons. That has not been our practice in the past. The Boundary Commissions have had the discretion to recommend the number of constituencies that they judge to be appropriate, which I think is more practical and more proper.
