If the changes are agreed by Parliament, the new constituencies will take effect at the next scheduled General Election in 2020.

Background on the review

The Boundary Commission for EnglandĀ is required by the Parliamentary Constituencies Act 1986 to review the parliamentary constituencies in England every five years.

Parliament has specified that the 2018 Review must reduce the number of constituencies in the UK to 600 (from the current 650). The law also requires that every new constituency must have roughly the same number of electors: no fewer than 71,031 and no more than 78,507.
