Corby and East Northamptonshire (UK Parliament constituency)

Corby and East Northamptonshire is a constituency in the English county of Northamptonshire. It is represented in the House of Commons of the UK Parliament since July 2024 by Lee Barron, of the Labour Party.

Prior to the 2023 Periodic Review of Westminster constituencies, the constituency was known as Corby. The 2024 general election was the first general election in which the 'Corby and East Northamptonshire' constituency was contested following the boundary changes of 2023.

History
From 1832 – 1918, the village of Corby was part of the North Northamptonshire constituency, which consisted of most of the Soke of Peterborough, the towns of Oundle and Thrapston and the surrounding villages and hamlets of north-eastern Northamptonshire.

The North Northamptonshire constituency boundaries were changed slightly in 1885, with some of the constituency being transferred to the newly created Mid Northamptonshire constituency. However, Corby remained within the revised constituency of North Northamptonshire.

The North Northamptonshire constituency was abolished in 1918 for that year's general election, and from 1918 – 1950, Corby was part of the Peterborough constituency. The Peterborough constituency consisted of most of the former North Northamptonshire constituency – including the Soke of Peterborough, Corby, Oundle, Thrapston and surrounding villages.

Boundary changes for the 1950 general election saw Corby transferred to the Kettering constituency; Corby remained part of the Kettering constituency until 1983. The Parliamentary seat of 'Corby' was created due to population increases in and around the town of Corby for the 1983 general election. Since creation, the Corby constituency has been a marginal seat alternating between Labour and the Conservative representatives with marginal majorities relative to national averages on all but two occasions, the 1997 Labour landslide and the 2012 by-election. The first Member of Parliament elected for the constituency in 1983 was William Powell, who represented the Conservatives for three sessions of Parliament until 1997. Labour then held the seat until 2010.

On 6 August 2012, MP for the seat since 2010 Louise Mensch (formerly Louise Bagshawe) announced she was resigning, triggering a by-election held on 15 November 2012. Labour's Andy Sawford won, becoming the first Labour MP for the seat since Phil Hope was defeated in 2010, and only the second in the seat's history. This was Labour's first by-election win from a Conservative since the 1997 Wirral South by-election. At the 2015 general election Tom Pursglove standing for the Conservatives won with a small majority. He won again with a similar margin in 2017 and in 2019 Tom Pursglove took the seat for the third time, but with a majority of over 10,000, turning Corby into a non-marginal seat by Conservative Party standards.

At the 2024 general election, the seat was gained by Labour's Lee Barron amidst their national landslide victory, continuing the seat's bellwether streak of voting for the party that won nationally at every general election since its creation in 1983.

2021–2024: With effect from 1 April 2021, the Borough of Corby and the District of East Northamptonshire were abolished and absorbed into the new unitary authority of North Northamptonshire. From that date, the constituency comprised the District of North Northamptonshire wards of Corby Rural, Corby West, Irthlingborough, Kingswood, Lloyds, Oakley, Oundle, Raunds and Thrapston.

The constituency was created in 1983 from parts of the seats of Kettering and Wellingborough. It is named after the town of Corby in Northamptonshire, and also covers much of the local government district of East Northamptonshire, but excluding Rushden and Higham Ferrers which are in the Wellingborough constituency. The seat is a highly marginal contest between the Tories and Labour, with Labour's vote strongest in the town of Corby itself, against the solidly Conservative rural areas of East Northamptonshire.

The constituency was sometimes informally called "Corby and East Northamptonshire", but the 2007 Parliamentary Constituencies Order and Whitaker's Almanack both make it clear that, until 2024, its official name was "Corby".
