Parliamentary Voting System and Constituencies Bill

Further to that point, does my hon. Friend recognise that because of the arithmetical formula, the Bill will ensure not just that boundaries will change every five years, but that the number of seats allocated to each Boundary Commission could change? The number of seats in Northern Ireland could go up in one review and down in another, and that in turn would affect the seats in the Northern Ireland Assembly, because the constituencies of the Assembly and of Parliament are absolutely coterminous. The proposal will create havoc.
