Boundary commissions (United Kingdom)

In the United Kingdom, the boundary commissions are non-departmental public bodies responsible for determining the boundaries of parliamentary constituencies for elections to the House of Commons.^[1] There are four boundary commissions: one each for England, Scotland, Wales and Northern Ireland.

Each commission comprises four members, three of whom take part in meetings. The speaker of the House of Commons chairs each of the boundary commissions ex officio but does not play any part in the review, and a High Court judge is appointed to each boundary commission as deputy chair.^[2]
