Parliamentary Voting System and Constituencies Bill

On this occasion, my hon. Friend has not lost me with his amendment, although I am astonished at where it has originated. Will he explain exactly how it will be more effective and quicker for staff at a polling station to have two separate registers, given that they will not know which elections people are eligible to vote in, and especially given that, under another of his amendments, voters would have only one polling card to present? Would his amendment (g) not lead to the possibility of queues not just at 10 o'clock but throughout the day, with people trying to find out whether they were eligible to vote, because staff would have to check two registers rather than one?
