What is The Boundary Commission?

The Boundary Commission for England (BCE) is an independent and impartial non-departmental public body, which is required by Parliament to review Parliamentary constituency boundaries in England.

It conducts a review of all the constituencies in England every five years. Its role is to make recommendations to Parliament for new constituency boundaries.

It also makes recommendations for any changes in the names of individual constituencies.
