The Commission carried out a second consultation in the Spring 2017.
Following this secondary consultation, the Commission will review all representation received and will consider whether any revisions are needed. If they decide to revise the proposals, another consultation will take place on the revised boundaries towards the end of 2017 or in early 2018.
All representations have been published at www.bce2018.org.uk, where you can search by a number of different options, such as name, reference number, existing constituency or type of respondent, as well as using the interactive mapping system to locate comments geographically.
Parliamentary boundaries define the geographic area represented by each MP - known as their parliamentary constituency.
A parliamentary boundary review examines the existing constituencies and makes recommendations for any changes that are needed to ensure that constituencies comply with legal requirements, which make sure that the number of electors in each constituency is broadly equal, whilst also taking into account factors such as local community ties.
The 2018 Review will deliver its recommendations in September 2018.
One of the key requirements of the review is to reduce the number of constituencies in the UK to 600 (from 650) across England, Northern Ireland, Scotland and Wales. Within England alone the number of constituencies will reduce from 533 to 501.
To achieve this, the Boundary Commission must review and recommend where the new constituency boundaries should be. By law these must have roughly the same number of electors - no fewer than 71,031 and no more than 78,507.
