Blyth Valley, formerly known as Blyth, is a constituency represented in the House of Commons of the UK Parliament since 2019 by Ian Levy, a Conservative. Constituency profile The constituency is in the former Northumberland Coalfield where mining and shipbuilding were once significant industries. Residents' incomes and wealth are slightly below average for the UK. History The constituency of Blyth was established under the Representation of the People Act 1948 for the 1950 general election. Following the reorganisation of local authorities resulting from the Local Government Act 1972, it was renamed Blyth Valley for the 1983 general election to correspond with the newly formed Borough of Blyth Valley. In the 2019 general election, Blyth Valley was the third seat to declare and the first Conservative victory of the election, pointing towards many similar Conservative victories in Labour's Red Wall as the night went on. Boundaries 1950–1983 (Blyth) the Municipal Borough of Blyth; and the Urban Districts of Bedlingtonshire, and Seaton Valley. Blyth and Bedlington were transferred from Morpeth. Seaton Valley (incorporating Cramlington, Seghill, Earsdon and Seaton Delaval) was added from the abolished constituency of Wansbeck. 1983-present (Blyth Valley) The boundaries were co-terminous with those of the former Borough of Blyth Valley. Bedlington was transferred to the re-established constituency of Wansbeck. Small area in the south (Backworth and Earsdon), which was now part of the metropolitan borough of North Tyneside in Tyne and Wear, transferred to Wallsend. 2007 boundary review In the fifth periodic boundary review of parliamentary representation in Northumberland, which came into effect for the 2010 general election, the Boundary Commission for England recommended that no changes be made to the Wansbeck constituency. In 2009, a further government reorganisation resulted in the abolition of all local government boroughs and districts in Northumberland and the establishment of the county as a unitary authority. Accordingly, although this has not affected the current constituency boundaries, the constituency now contains the Northumberland County Council wards of: Cowpen, Cramlington East, Cramlington Eastfield, Cramlington North, Cramlington South East, Cramlington Village, Cramlington West, Croft, Hartley, Holywell, Isabella, Kitty Brewster, Newsham, Plessey, Seghill with Seaton Delaval, South Blyth, and Wensleydale.
