Creation

The seat was created in 1983 as part of the reconfiguration of those in the county to avoid malapportionment, abolishing Oxford as a seat. It merged about half the city with the eastern portion of the former Abingdon seat.

MPs

Conservative John Patten (MP for Oxford in the 1979–1983 Parliament), held the seat from its creation until he retired in 1997. The seat was gained by Liberal Democrat, Evan Harris, who held the seat for thirteen years until the 2010 general election, when the Conservative Nicola Blackwood retook the seat in one of the most marginal results of that election. Blackwood held the seat until the 2017 general election, when she was defeated by Liberal Democrat Layla Moran in another marginal result. Moran retained the seat at the 2019 general election with a much increased majority of 15.2%.

Contests

The seat has been contested nine times, each of them general elections. At each contest, the Labour party candidate has polled third, with the peak share of votes to date being 20.2% in 1997. The strongest victory, in share of the vote, was that of Harris of the Liberal Democrats in 2001, a 17.8% majority (in a seven-way contest).

The Green Party and its predecessor, the Ecology Party, stood in the first eight contests, in each losing the deposit paid.

In December 2023, the Labour Party included the seat in its published list of 211 non-battleground seats, suggesting they did not see it as winnable.^[3]

1983–1997

• The District of Vale of White Horse wards of Abbey, Caldecott, Cumnor, Fitzharris, Hinksey, Kennington, Northcourt, Ock, Radley, St Helen Without, and Sunningwell and Wootton; and
• The City of Oxford wards of Central, Cherwell, North, South, West, and Wolvercote.^[4]

The majority of the new constituency, comprising the town of Abingdon-on-Thames and areas to the west of Oxford, was previously part of the abolished constituency of Abingdon in Berkshire. The City of Oxford wards had previously been in the abolished constituency of Oxford.

1997–2010

• The District of Vale of White Horse wards of Abbey, Caldecott, Cumnor, Fitzharris, Hinksey, Kennington, Northcourt, Ock, Radley, St Helen Without, and Sunningwell and Wootton;
• The City of Oxford wards of Central, Cherwell, North, West, and Wolvercote; and
• The District of Cherwell wards of Gosford, North West Kidlington, and South East Kidlington.^[5]

Kidlington was transferred from Witney. The South ward of the City of Oxford was transferred to Oxford East.

2010-present

• The District of Vale of White Horse wards of Abingdon Abbey and Barton, Abingdon Caldecott, Abingdon Dunmore, Abingdon Fitzharris, Abingdon Northcourt, Abingdon Ock Meadow, Abingdon Peachcroft, Appleton and Cumnor, Kennington and South Hinksey, North Hinksey and Wytham, Radley, and Sunningwell and Wootton;
• The City of Oxford wards of Jericho and Osney, North, St Margaret's, Summertown, and Wolvercote; and
• The District of Cherwell wards of Kidlington North, Kidlington South, and Yarnton, Gosford and Water Eaton.^[6]

Further loss to Oxford East, including the city centre, following revision of City of Oxford wards; marginal realignment of boundary with Wantage; Yarnton transferred from Witney.

Proposed

Further to the 2023 Periodic Review of Westminster constituencies, enacted by the Parliamentary Constituencies Order 2023, from the next general election, due by January 2025, the constituency will be composed of the following (as they existed on 1 December 2020):

• The following wards of the City of Oxford wards of: Carfax & Jericho; Cutteslowe & Sunnymead; Holywell; Osney & St. Thomas; Summertown; Walton Manor; Wolvercote.
• The District of Vale of White Horse wards of: Abingdon Abbey Northcourt; Abingdon Caldecott; Abingdon Dunmore; Abingdon Fitzharris; Abingdon Peachcroft; Botley & Sunningwell; Cumnor; Kennington & Radley; Marcham; Wootton.^[7]

The electorate will be reduced to bring it within the permitted range by transferring Kidlington to the newly created constituency of Bicester and Woodstock. To partly compensate, Oxford city centre and University colleges will be moved back in from Oxford East. In addition, the village of Marcham will be transferred from Wantage.
