Yes, Minister. Northern Ireland is obviously geographically the smallest part of the United Kingdom, so we literally have less room for manoeuvre when it comes to creating our modelling of the constituencies. That can be compounded by the effects of rounding during the calculations under rule 8, when it comes to allocating constituencies to each part of the UK.
That can leave us restricted in our ability to create the correct number of constituencies under rule 2. The legislation does currently, and I think the new legislation does prospectively, include a small degree of flexibility that allows us to fall beneath or outside of the plus or minus 5% tolerance from the electoral quota, but as I say, that is there because it recognises the mathematical conundrum that can sometimes present itself in Northern Ireland.
