Corby and East Northamptonshire is aconstituency^{[n 1]} in the English county ofNorthamptonshire. It is represented in theHouse of Commons of theUK Parliament since July 2024 byLee Barron, of the Labour Party.^{[n 2]}

Prior to the2023 Periodic Review of Westminster constituencies, the constituency was known asCorby. The2024 general election was the first general election in which the 'Corby and East Northamptonshire' constituency was contested following the boundary changes of 2023.^[2]

From 1832 – 1918, the village of Corby was part of theNorth Northamptonshire constituency, which consisted of most of theSoke of Peterborough, the towns of Oundle and Thrapston and the surrounding villages and hamlets of north-eastern Northamptonshire.^[3]

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.^[4]

The North Northamptonshire constituency was abolished in 1918 forthat year's general election, and from 1918, Corby was part of 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 the1983 general election. Since creation, the Corby constituency has been amarginal seat being won by the party that won the national election at each general election since its creation, with Corby inclined towards Labour, and the rural towns and villages of East Northamptonshire mostly Conservative. 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 2010Louise Mensch (formerly Louise Bagshawe) announced she was resigning, triggering aby-election held on 15 November 2012. Labour'sAndy Sawford won, becoming the first Labour MP for the seat sincePhil 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 the1997 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 the2024 general election, the seat was gained by Labour'sLee Barron amidst their national landslide victory, continuing the seat'sbellwether 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 ofNorth Northamptonshire.^[5] 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 ofKettering andWellingborough. It is named after the town ofCorby inNorthamptonshire, and also covers much of the local government district ofEast Northamptonshire, but excludingRushden andHigham Ferrers which are in theWellingborough constituency. The seat is a highlymarginal 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.^[6]

The constituency was sometimes informally called "Corby and East Northamptonshire",^[7] but the 2007 Parliamentary Constituencies Order^[8] andWhitaker's Almanack both make it clear that, until 2024, its official name was "Corby".

• Corby Rural (part); Corby West; Irthlingborough (part); Kingswood; Lloyds; Oakley; Oundle; Raunds; Thrapston.^[9]
