Parliamentary Voting System and Constituencies Bill

I very much agree with what the hon. Gentleman has to say, but does he not recognise that we have already enshrined PR in our political system to quite a large extent, through the European Parliament since 1999, through the way we elect the Scottish Parliament, Welsh Assembly and London assembly, and through the way in which local authorities are elected in Scotland? We are going down precisely that path, but it is a slippery slope that we started down quite some time ago.
