Parliamentary Voting System and Constituencies Bill

The amendment would give the Boundary Commission the discretion to propose constituencies within an extended 15% range of the UK electoral quota in the event that a commission considered that exceptional local ties or geographical circumstances made it necessary for a viable constituency. That means that the plus or minus 5% rule could be extended to plus or minus 7.5% in the exceptional circumstances set out in the amendment. The Government believe that the principle of ““one vote, one value””, so that there are votes of more equal weight across the country, is paramount. That is the fundamental principle underpinning the Bill. It is not an abstract concept, nor is it, as some of our opponents like to say, about a slavish adherence to arithmetic. It is right for electors across the UK to have an equal say not just in who will be their local representative, but in who will form the Government of the day. For votes to have equal weight in a single member constituency system, the constituencies must contain a broadly equal number of electors. The existing legislation that determines how the boundaries are to be drawn—the Parliamentary Constituencies Act 1986—also has that principle at its heart. Indeed, in one sense it could be argued that it involves a tighter rule, because it suggests that the Boundary Commission should aim for exact numerical equality, but the rules in that Act are contradictory and compromise the principle of equality. We see the large variations in the sizes of constituencies at the moment, which is why the Government's proposals set a clear range for the number of electors that a constituency may contain. I have already said that absolute equality is not practicable. There are a small number of specific exceptions, which recognise the practicalities of genuinely challenging geography: those are the two provisions that we inserted into the Bill at the beginning. I will not dwell on the subject of the Isle of Wight now; we will have an opportunity to do so later. More generally, the Bill allows for constituencies to vary by 5% either side of the quota. On the basis of the register data for 2009, that is about 8,000 electors. Within that range, commissions can take account of local circumstances.
