Parliamentary Voting System and Constituencies Bill

I never once referred to combined elections. That is not the issue as far as my amendment is concerned; I know that others in the group are concerned with this. My question is this: what were the relevant dates for that legislation? I know the referendum the noble Lord, Lord Tyler, refers to was for London only and not national, but how close to the referendum did the legislation start through the two Houses? That is the point that I am raising. I am not arguing against 5 May; I am just saying that if something goes wrong between now and then, my amendment is a lifeboat and we can still have the referendum.
