I beg to move, That the Clause be read a Second time.

I hope that Members’ heads have not been hurting too much in trying to understand this new clause, which gives a discretionary power in certain circumstances to all boundary commissions, when considering a grouping of constituencies, that currently applies only to the Boundary Commission for Northern Ireland when considering those constituencies as a whole.

Boundary commissions have always worked by grouping areas together and designing constituencies within those areas. For parliamentary reviews, areas will be formed by grouping local authorities. Sometimes the initial set of groupings does not work and other things are considered. The Boundary Commission for Scotland helpfully publishes all its minutes at the start of the initial consultation period and, indeed, makes available maps of its rejected proposals as well, so that people can see exactly how it has come to its conclusions.

Let us say that we are designing 10 constituencies in an area with an electorate roughly equal to the UK electoral quota multiplied by 10. We would be able to use the plus or minus 5% variation to its full throughout the area to design our 10 constituencies. A problem arises when the electorate of the 10 constituencies combined represents somewhere between 95% and 105% of the UK electoral quota multiplied by 10, because the scope for variation then becomes very limited, meaning that, to retain the grouping, constituencies will have to be designed with very little scope for numerical variation. That can often lead to what looks like logical groupings being abandoned unnecessarily.

The problem was recognised in Northern Ireland, which was allocated 16 and then 17 seats in the two reviews under the current legislation. Current rule 7 allows the use of a Northern Ireland quota in defined circumstances. The Northern Ireland quota is simply the number of electors in Northern Ireland divided by the number of constituencies allocated. Use of that quota means the full plus or minus 5% variation for constituencies is then effectively reinstated.

To pre-empt what the Minister might say, there was an obscure issue in Northern Ireland in the last review around the point at which the decision to apply the rule was made, which resulted in litigation. I stress that that was very much a procedural issue, which was not relevant to the essential utility of the rule. The problem in Northern Ireland was a numerical one. It is not one in special recognition of the politics there. The numerical problem applies throughout the United Kingdom when we group constituencies, as all boundary commissions do.

I therefore look forward to hearing the Minister’s position and her explanation of why what is good for Northern Ireland is not good for all the other boundary commissions when faced with the identical issue. On that basis, I will draw my remarks to a close and listen to what the Minister has to say on new clause 7.
