Parliamentary Voting System and Constituencies Bill

Like my hon. Friend, I am a supporter—and always have been—of AV. He mentioned the Labour party, and of course the Labour party has no policy, but has not the Labour movement long held the principle that in trade union rule changes there should be a threshold precisely because rule changes are irreversible, in that they must be implemented? Should not the principle of a threshold mean that the Government should be looking for significantly more than 326 votes on Third Reading tonight to demonstrate any kind of support for this rotten Bill?
