Parliamentary Voting System and Constituencies Bill

My Lords, I start by indicating to the noble Lord, Lord Lipsey, that in the days when I had to attend economics lectures from the noble Lord, Lord Eatwell, I also had to read Richard Lipsey’s Positive Economics. I hope he will take it in the spirit that it is intended when I say that I find the noble Lord’s contributions much more engaging than what I recall of his textbook. The amendment would allow the Boundary Commission to decide, in particular instances, that the factors in rule 5 are so important that it should override the preceding rules. It has been evident from the debates that we have had so far that the core principle of this part of the Bill is to ensure that votes cast across the country have an equal weight. The best way to achieve this is to ensure that there is broad equality in the number of registered voters in each constituency. The principle of parity must be paramount. In introducing his amendment, the noble Lord said that there was consensus in the Committee on the principle of equity, although he indicated that there was no consensus on the 5 per cent or 10 per cent variation from the electoral quota figure. I pay tribute to the noble Lord’s ingenuity for coming forward with this amendment. He claims that it is a very narrow exemption but, while ostensibly reasonable, the amendment would undermine the principle of parity that we have said ought to be paramount by allowing other factors to take precedence over the equal weighting of votes. This could, and almost certainly would, perpetuate a situation in which constituencies can be of very different sizes, and votes cast in one part of the country can have a very different weight from those cast in another. The amendment would override rule 2(1), so it would not just be a question of a debate about a 5 per cent or 10 per cent variation. Indeed, by that rule being overridden, the variation could be sizeable indeed. Existing differences in constituency size matter. There is a 41 per cent difference between Manchester Central, with 85,522 electors in 2009, and Glasgow North, with 50,588 electors in 2009. That means that 10 voters in Glasgow North have the same weight as 17 voters in Manchester Central. Frankly, that simply cannot be right.
