# Cambridge (UK Parliament constituency)

Cambridge is a constituency represented in the House of Commons of the UK Parliament since 2015 by Daniel Zeichner of the Labour Party.
Centred on the university city of Cambridge, it is one of the country's oldest continuously constituted constituencies. It was created in 1295 and returned two Members of Parliament (MPs) and was 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.
It was held by the Conservatives from 1967 to 1992, since when it has been represented alternately by both Labour and the Liberal Democrats.
In the 2016 referendum to leave the European Union, the constituency voted 73.8% to remain.

## Constituency profile

The current constituency covers the majority of the city of Cambridge, including the areas of Arbury (which contains some social housing), Chesterton, Newnham, Cherry Hinton and the village of Trumpington; but the city's Queen Edith's ward (which includes Addenbrooke's Hospital and Homerton College) is in the neighbouring South Cambridgeshire constituency.
Residents are healthier and wealthier than the UK average.

## History
### Overview of results before 1992

Cambridge returned two Members to Parliament from 1295 until 1885, using the bloc vote system. These were generally townsmen who were involved in local government, with at least sixty mayors of Cambridge having served as MP by 1621. Under the Redistribution of Seats Act 1885 representation was reduced to one member, using the first-past-the-post system, with effect from the 1885 general election.
From 1910 to 1992, Cambridge was won by the Conservatives, save for 1945 to 1950 and 1966 to 1968, when it was Labour-held with small majorities.

#### Related extra representation 1603–1950

Historically, the city of Cambridge retained some electors, and was often the source of MPs to a second constituency, for Cambridge University, covering all successful alumni in its electorate. The university seat was created in 1603 as part of the scheme of University constituencies. Its MPs included Isaac Newton, William Pitt the Younger, Lord Palmerston, George Stokes, Richard Jebb, and Archibald Hill before abolition in 1950.

### Overview of results since 1992

In 1992, Cambridge was won by Labour's Anne Campbell, who held onto the seat for 13 years (three Parliamentary terms). In 2005, it was taken by David Howarth of the Liberal Democrats, the first time the party (including its two forerunner parties) had taken the seat since the 1906 Liberal-progressive landslide; his successor, Julian Huppert, held the seat with an increased majority in the 2010 general election. In 2015, Huppert was unseated by the Labour candidate, Daniel Zeichner, who took the seat with a thin majority of 599 votes. The 2015 result gave the seat the 7th-smallest majority of Labour's 232 seats by percentage of majority. Zeichner went on to hold the seat at the 2017 and 2019 elections with comfortable majorities.

#### Most recent results of other parties

In 2015, three other parties candidates kept their deposits, by winning more than 5% of the vote. In order of public preference, these candidates stood for the Conservatives, Green Party and UKIP, respectively.

#### Turnout since 1918

Turnout at general elections has ranged between 86.48% in 1950 to 60.6% in 2001.
