Parliamentary Voting System and Constituencies Bill

I may be a new Member of this House, but I know that you do not get sequential interventions without a response. I am grateful to my noble friend for raising those powerful and valid points. I have long wondered why, if one party wanted 500 and the other wanted 585, we did not have 542 and half. So this is a random figure that has been plucked out of thin air. It ill behoves the noble Lord, Lord McNally, to keep avoiding the issue of why it is 600. Or is it exactly as the Leader of the House said, a nice, round number? If he thinks we believe that, he must think that we are demented.
