Historic (Corby) 1983–2010: The District of Corby, and the District of East Northamptonshire wards of Barnwell, Brigstock, Drayton, Forest, Irthlingborough, King's Cliffe, Lower Nene, Margaret Beaufort, Oundle, Raunds, Ringstead, Stanwick, Thrapston, Willibrook, and Woodford.
2010–2021: The Borough of Corby, and the District of East Northamptonshire wards of Barnwell, Dryden, Fineshade, Irthlingborough, King's Forest, Lower Nene, Lyveden, Oundle, Prebendal, Raunds Saxon, Raunds Windmill, Ringstead, Stanwick, Thrapston, and Woodford.
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".
Current (Corby and East Northamptonshire) Following the
2023 review of Westminster constituencies, which came into effect for the
2024 general election, the constituency is composed of the following wards of the District of North Northamptonshire: • Corby Rural (part); Corby West; Irthlingborough (part); Kingswood; Lloyds; Oakley; Oundle; Raunds; Thrapston. :
Parts of the Corby Rural and Irthlingborough wards were transferred to Kettering, and Wellingborough and Rushden respectively. ==Members of Parliament==
