Overview of the Bill
1 This Bill seeks to amend changes made by the Parliamentary Voting System and Constituencies Act 2011 to the Parliamentary Constituencies Act 1986. First, the Bill reverses the reduction in the size of the House of Commons from 650 to 600 Members. Second, it increases the flexibility permitted in the size of the electorate in most constituencies from 5% to 10% of the average (excepting four island seats). Third, the Bill requires the calculation of the size of the total electorate to be based on registers of parliamentary electors published in or after 2017. Fourth, the Bill requires the Boundary Commissions to complete their reviews of parliamentary boundaries by 1 October 2018 and thereafter to carry out reviews every ten years.
