Parliamentary Voting System and Constituencies Bill

I am not delaying the debate, but there will be people in the Chamber who have not been here during our previous debates and who are wondering why we are going on a register that is based on December 2010. Why cannot we wait, let us say, 12 months? If we were to wait 12 months, could we not get a boundary inquiry in and the new boundaries introduced for the next general election? Will the Minister explain why we have to have a register that is based on the end of last year and not, perhaps, later this year?
