I thank the hon. Gentleman for giving way; he is making a thoughtful speech. Has he considered the single transferable vote system? He rightly says that the constituency link is important. We use that system to elect local councillors in Scotland. The link is maintained, but there is also greater proportionality.
On the problems that the hon. Gentleman identifies, would he accept that the two-party dominance of the first-past-the-post system is being stretched to breaking point, with broad churches forming that are beyond having meaning? Part of the problem that we are seeing in our politics is down to the voting system itself.
