Parliamentary Voting System and Constituencies Bill

The hon. Gentleman has spelled out exactly what lies ahead with this Bill. There is uncertainty over the changes that will come with the introduction of this Bill but, in addition, in every single Parliament there will be an arithmetic play-off over who gets the last bundle of seats out of the 600. Does a party qualify under Sainte-Laguë for an extra seat, or does it end up losing a seat in Scotland, Wales or in Northern Ireland? The boundary commission will then be asked to deal with the consequences again.
