the wards of Chevington, Ellington, Hartburn, Longhorsley, Lynemouth and Ulgham. Contents changed following reorganisation of local authorities in 1974. The seat was expanded southwards, adding the (rural) wards in Castle Morpeth Borough, previously part of the abolished constituency of Morpeth. 2007 boundary review In the fifth periodic boundary review of parliamentary representation in Northumberland, which came into effect for the 2010 general election, the contents of the existing Berwick constituency were unchanged and the Boundary Commission for England made only minor changes to take account of ward boundary changes. A proposal to rename the historic seat "Berwick-upon-Tweed and Mid Northumberland" was rejected: whilst it is geographically accurate, it was thought unwieldy.

In doing so she became only the third female MP to sit in the House of Commons since female members became legal five years previously.
