Parliamentary Voting System and Constituencies Bill

I wonder whether the noble Lord is trying to make it difficult for the referendum to be held on 5 May, in contrast to the noble Lord, Lord Rooker, who said specifically that he was arguing in his amendment that the referendum could be held on 5 May or at a later date if that was more convenient. Is the position of the noble Lord, Lord Rooker, not wholly different from that advanced by the noble Lord, Lord Grocott, who is trying to make it difficult to have the referendum on the day that the other place has voted for it to be held on?
