Parliamentary Voting System and Constituencies Bill

My noble friend is making a fascinating series of points which, to someone from my background, is a new experience. Given the point made by the noble Lord, Lord Lester, about the responsibility of political parties to ensure voter registration, does my noble friend agree that there is a real danger that if we put responsibility exclusively on to the political parties, we are in danger of going down the US route, where you end up with either a registered Democrat or a registered Republican, and the middle ground of politics—ironically, the middle ground which the Liberal Democrats should be seeking to enter—becomes extremely blurred? We would change the nature of the political system in this country, which is why we have an independent Electoral Commission and boundary commissioners.
