The Boundary Commission for England is the independent organisation responsible for reviewing parliamentary constituency boundaries.
During 2017 and early 2018, the Boundary Commission for England published and consulted on their initial and revised proposals for new constituency boundaries.
The Boundary Commission for England finished the 2018 Review of constituency boundaries on 5 September 2018 (when it reported the final recommendations to Government).
The final recommendations are available to view at www.bce2018.org.uk
The Government laid the recommendations in Parliament for consideration on 10 September 2018. The Government must then prepare a Statutory Instrument (SI) that would implement the recommendations (along with any recommendations from the Boundary Commissions for the other parts of the UK). Both Houses of Parliament must vote on these SIs before they become law. If both houses approve the SI, the new boundaries would come into force at the next general election after that vote. If they are not voted through by both houses, the existing boundaries will continue to apply for future general elections.
