Parliamentary Voting System and Constituencies Bill

We settled on 600 MPs, a relatively modest cut in House numbers of just less than 8%, because it saves money—about £12 million each year—and because we think it creates a House that is sufficiently large to hold the Government to account while enabling us all to do our jobs of representing our constituencies. It also creates a sensible average number of constituents—76,000, as I mentioned earlier—that we already know is manageable because there are already 218 seats that are within 5% of that number. That is why we feel 600 is about right.
