Peterborough is a borough constituency represented in the House of Commons of the Parliament of the United Kingdom since July 2024 by Andrew Pakes of the Labour 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 earliest known members representing Peterborough were in 1547, shortly after it had gained city status, when Peterborough Cathedral became the seat of the new diocese of Peterborough in 1541. The cathedral had been Peterborough Abbey until the dissolution of the monasteries abolished it in 1539. The new city was not an ancient borough, nor a municipal borough until 1876; no charter survives granting the status of city or the right to Parliamentary representation or delimiting its boundary for electoral purposes. The borough franchise was scot and lot in the parish and householder in the Minster Precincts. For parliamentary purposes, the rest of the Soke of Peterborough, north and west of the city, was in the county constituency of Northamptonshire; the area south of the River Nene was in Huntingdonshire; to the east, Thorney was in Cambridgeshire.
The 1832 acts extended the parliamentary borough of Peterborough to the entire parish of Saint John the Baptist (adding 48 qualifying properties Under the Redistribution of Seats Act 1885, the borough's representation was reduced from two MPs to one.
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 Gretton; 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
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.
1997–2010
- The City of Peterborough wards of Bretton, Central, Dogsthorpe, East, North, Park, Paston, Ravensthorpe, Walton, Werrington and West
The next redistribution, which came into effect for the 1997 general election, saw the creation of North West Cambridgeshire, which took the areas to the south of the River Nene (City of Peterborough wards of Fletton, Orton Longueville, Orton Waterville and Stanground). Werrington was transferred back from Huntingdon.
2010–2024
- The City of Peterborough wards of Bretton North, Bretton South, Central, Dogsthorpe, East, Eye and Thorney, Newborough, North, Park, Paston, Ravensthorpe, Walton, Werrington North, Werrington South and West
Following their review of parliamentary representation in Cambridgeshire which came into effect for the 2010 general election, the Boundary Commission for England made minor alterations to the existing constituencies to deal with population changes, primarily the transfer back of Thorney and Eye from North East Cambridgeshire. There were also marginal changes to take account of the redistribution of City of Peterborough wards. These changes increased the electorate from 64,893 to 70,640. On the enumeration date of 17 February 2000, the electoral quota for England was 69,934 voters per constituency.
Marginal loss due to further ward boundary changes.
The current constituency is composed of built-up areas of Peterborough to the north of the River Nene, as well as rural areas to the east and north and comprises approximately 60% of the electorate of the local authority of the City of Peterborough. Remaining parts of the city, composed of residential areas to the south of the River Nene and rural areas to the west of Peterborough form part of the North West Cambridgeshire constituency. Bribery was general until the introduction of the secret ballot under the Ballot Act 1872. Votes were cast by spoken declaration, in public, at the hustings, erected on the Market Place (now Cathedral Square).
The Great Reform Act 1832 enfranchised those who owned or leased land worth £10 or more and the Second Reform Act extended this to all householders paying £10 or more in rent per annum, effectively enfranchising the skilled working class, so by 1868 the percentage of voters in Peterborough had risen to about 20% of the population. The Third Reform Act extended the provisions of the previous act to the counties and the Fourth Reform Act widened suffrage further by abolishing practically all property qualifications for men and by enfranchising women over 30 who met minimum property qualifications. This system, known as universal manhood suffrage, was first used in the 1918 general election. However, full electoral equality would not occur until the Fifth Reform Act ten years later.
According to the 2001 census, the population count of Peterborough constituency is 95,103 persons, comprising 46,131 males and 48,972 females. 67.56% of those aged 16–74 are economically active, including 5.92% unemployed; a further 12.26% are retired and 3.08% students. Of a total 39,760 households, 63.80% are owner occupied, fewer than the regional (72.71%) and national (68.72%) averages. Turnout at the 2005 general election was 41,194 or 61.0% of those eligible to vote, below the regional (63.6%) and national (61.3%) figures.
Members of Parliament

Peterborough sent two members to parliament for the first time in 1547. Before the civil war, many were relatives of the clergy; then for two hundred years after the restoration there was always a Fitzwilliam, or a Fitzwilliam nominee, sitting as member for Peterborough, making it a Whig stronghold. Representation was reduced to one member under the Redistribution of Seats Act 1885.
One of the earliest incumbents, Sir Walter Mildmay, member for Peterborough from 1553 to 1554, subsequently became Chancellor of the Exchequer from 1559 to 1589. Later, in the nineteenth century, William Elliot, Whig member from 1802 until his death in 1819, was Chief Secretary to the Lord Lieutenant of Ireland between 1806 and 1807; the Hon. William Lamb (later the 2nd Viscount Melbourne), Whig member from 1816 to 1819, became Home Secretary in 1830 then Prime Minister from 1834 to 1841; and Sir James Scarlett (later the 1st Baron Abinger), Whig member from 1819 to 1830, was, from 1827, Attorney General for England and Wales.
From the formal merger of the breakaway Liberal Unionists with the Conservatives in 1912 and the absorption of rural North Northamptonshire in 1918, Peterborough has been predominantly Conservative; however, it has elected Labour MPs several times from 1929 onwards.
Lord Burghley, as he then was, succeeded the socialist writer and illustrator, Frank Horrabin, who was born in the city and elected under the leadership of Ramsay MacDonald in 1929. David Cecil, 6th Marquess of Exeter, winner of 400m hurdles at the 1928 Summer Olympics, member of the International Olympic Committee for 48 years and chairman of the organising committee of the 1948 Summer Olympics, was the Conservative member from 1931 to 1943.
In 1966, in one of the closest polls in UK history, Sir Harmar Nicholls held the seat by three votes after seven recounts. Nicholls was the Conservative member from 1950 to 1974, when he lost in the October election of that year to Labour's Michael Ward, having held on by just 22 votes after four recounts in the election eight months earlier. The growth in the New Town from 1967 may in part account for Labour's victory here in 1974. In 1979, however, Ward lost the seat to the Conservative Brian Mawhinney, who would represent Peterborough for the entire duration of the incoming Conservative government and was a Cabinet Minister and Chairman of the Conservative Party during the second Major government (1992–97).
The seat was made more competitive in the 1997 boundary review by the formation of the North West Cambridgeshire seat, which incorporated the rural land outside Peterborough and several Conservative-inclined wards from the city. Since its formation, North West Cambridgeshire has been one of the safest Conservative seats in the country, whilst Peterborough was ranked 93rd in the Conservatives's one hundred most vulnerable seats (the ones which the other parties must take if there is to be a change of government) and 73rd on Labour's target list; these factors led Mawhinney to stand in North West Cambridgeshire instead. He retired as an MP in 2005 and was created Baron Mawhinney, of Peterborough in the county of Cambridgeshire.
Helen Clark (née Brinton) won the seat for Labour in 1997. She was defeated by Conservative candidate Stewart Jackson at the 2005 election, following which it was widely reported that Clark was planning to defect to the Conservative Party, an announcement which was not popular locally. However, by early June it emerged that while she had left the Labour Party, she had not in fact joined the Conservatives and did not intend to.
Jackson was re-elected in 2010 with an increased majority, which then fell in 2015. In 2017, Labour's Fiona Onasanya won a majority of 607; this result marked the first time since 1929 that Peterborough voted Labour in an election where the Conservatives won the national popular vote, and the first time it has ever elected a Labour MP in a year in which Labour did not form the government. Furthermore, Peterborough became one of five constituencies – the others being Croydon Central, Enfield Southgate, Leeds North West and Reading East – which elected Labour MPs in 2017 having not done so since 2001.

MPs 1660–1883
The Tories (or Abhorrers) and Whigs (or Petitioners) originated in the Court and Country parties that emerged in the aftermath of the civil war, although it is more accurate to describe them as loose tendencies, both of which might be regarded as conservative in modern terms. Modern party politics did not really begin to coalesce in Great Britain until at least 1784.

MPs 1885–1918
In 1832 the Tory Party evolved into the Conservative Party and in 1859 the Whig Party evolved, with Radicals and Peelites, into the Liberal Party. In opposition to Irish home rule, the Liberal Unionists ceded from the Liberals in 1886, aligning themselves with the Conservatives. The Labour Party was later founded, as the Labour Representation Committee, in 1900.
