Peterborough is a borough constituency represented in the House of Commons of the Parliament of the United Kingdom since 2019 by Paul Bristow of the Conservative Party.
Its current form is the direct, unbroken successor of a smaller constituency that was created in the mid-16th century returning two Members of Parliament (MPs) using the bloc vote system of election and represented in the House of Commons of England until 1707, then in the House of Commons of Great Britain from 1707 to 1800, and then in the House of Commons of the United Kingdom from 1801 to 1885. From 1885 onwards, the seat has elected one MP using the first-past-the-post system.
Boundaries and boundary changes
Prior to 1918
The City of Peterborough formed a parliamentary borough returning two members in 1541. The rest of the Soke of Peterborough was part of the Northamptonshire parliamentary county; the area south of the River Nene was in the historic county of Huntingdonshire and Thorney was considered part of Cambridgeshire. Until 1832 when the whole of the parish of Saint John the Baptist was encompassed, the boundary, as far as is known, excluded the villages of Longthorpe, Dogsthorpe and Newark with Eastfield. The Great Reform Act did not affect the borough, while the rural portion of the Soke was included in the Northern division of Northamptonshire. Under the Boundaries Act 1868, New Fletton and Woodstone were transferred from Huntingdonshire and, under the Redistribution of Seats Act 1885, the borough's representation was reduced from two to one MP.
1918-1950
The administrative county of the Soke of Peterborough (the Municipal Borough of Peterborough and the Rural Districts of Barnack and Peterborough); The Urban District of Oundle; The Rural Districts of Easton-on-the-Hill and Gretto; and Parts of the Rural Districts of Oundle and Thrapston
In 1918 the parliamentary borough was abolished and replaced with a new division of the parliamentary county of Northampton with the Soke of Peterborough, including the whole of the Soke (which had been created as a separate administrative county by the Local Government Act 1888) and neighbouring parts of the administrative county of Northamptonshire, absorbing the bulk of the abolished Northern division, incorporating Oundle and extending down to and beyond Thrapston and Corby.
1950-1974
The Municipal Borough of Peterborough; The Urban District of Oundle; The Rural Districts of Barnack and Peterborough; and Part of the Rural District of Oundle and Thrapston
Designated as a county constituency under the revisions brought in for the 1950 general election by the Representation of the People Act 1948, with only minor changes to the boundaries of the constituency to reflect a rationalisation of the rural districts of Northamptonshire.
1974-1983
The Municipal Borough of Peterborough; and
The Rural Districts of Barnack, Peterborough and Thorney
In 1965 the administrative counties of the Soke of Peterborough and Huntingdonshire were combined to form Huntingdon and Peterborough. At the next redistribution, which came into effect for the February 1974 general election, the constituency was redesignated as a Borough Constituency, composed of the local authorities which had comprised the Soke, together with the sparsely populated Rural District of Thorney, which was transferred from the administrative county/constituency of Isle of Ely. The parts in Northamptonshire were transferred to Wellingborough.
1983-1997
The City of Peterborough wards of Bretton, Central, Dogsthorpe, East, Fletton, North, Orton Longueville, Orton Waterville, Park, Paston, Ravensthorpe, Stanground, Walton and West
As a result of the Local Government Act 1972, the two counties of Huntingdon and Peterborough and Cambridgeshire and Isle of Ely were merged to form the non-metropolitan county of Cambridgeshire, with effect from 1 April 1974. However, the next redistribution did not come into effect until the 1983 general election, when areas to the south of the River Nene, including Fletton and the Ortons, which were now part of the expanded City of Peterborough, were transferred from the abolished constituency of Huntingdonshire. Mainly rural areas to the east (Thorney and Eye) and west (Barnack and Werrington) were transferred to the new constituencies of North East Cambridgeshire and Huntingdon respectively.
