Constituency boundaries have changed.
In 2023, the Boundary Commission for England (BCE) undertook a review of all constituencies in England, to rebalance the number of electors in each constituency.
The new map created by the Commission makes sure each constituency has between 69,724 and 77,062 electors so that each Member of Parliament (MP) represents roughly the same number of electors.
The 2023 Boundary Review also required that the number of constituencies in England increased from 533 to 543.
The Commission listened to the feedback sent in from the public and changed nearly half of the initial proposals.
You can find the final report and recommendations of the review on the Boundary Commission for England website.
