Parliamentary Voting System and Constituencies Bill

I am very grateful to the Minister for giving way. He has been extremely indulgent of these interventions, but they are very helpful if they discourage people from making speeches about issues that he has addressed. My question relates directly to the last point that he made, which is at least some recognition that there will be population movements, which must be accommodated in drafting constituency boundaries in anticipation. My understanding of the Bill is that even that minor recognition of population changes will not be possible if the Bill becomes law. Am I correct in that understanding?
