# Henley (UK Parliament constituency)

Henley was a constituency in Oxfordshire represented in the House of Commons of the UK Parliament from the 2008 to 2024 by John Howell, a Member of Parliament from the Conservative Party.
Under the 2023 review of Westminster constituencies, the constituency was subject to minor boundary changes. It was renamed Henley and Thame, and was first contested at the 2024 general election.

## Constituency profile

The seat has throughout its history consisted of the town of Henley, a part of the Chiltern Hills AONB interspersed by the larger settlements of Thame and Chinnor, and a narrow, more developed area adjoining the Thames on one bank. The local economy, interconnected with London, Oxford and in the far south Reading, ensures a high rate of employment and its natural environment attracts retirees and high income owners. The seat has good rail connections to Central London. As of 2021, the largest town in the constituency is Thame.

## History

The constituency was established under the Redistribution of Seats Act 1885 for the 1885 general election when the three-member Parliamentary County of Oxfordshire was divided into the three single-member seats of Banbury, Woodstock and Henley.
Prominent members
Two prominent Cabinet ministers have been elected for Henley. Michael Heseltine served as the MP for Henley from 1974–2001. Heseltine was succeeded by the future Mayor of London and Prime Minister Boris Johnson, rapidly made a shadow minister during the period of the Labour government. In May 2008, Johnson was elected as Mayor of London, and he subsequently resigned from the Commons on 4 June 2008, resulting in a by-election in the constituency, which was won by John Howell.

### Political history

An unbroken succession of Conservative candidates have won the seat since 1910. The 2008 by-election was closer than general elections since 2001 and won by the Conservative candidate, John Howell. Howell was re-elected at the 2010 general election and again in 2015, when Labour finished second for the first time since 1970 in Henley. The 2015 GE result made the seat the twelfth safest of the Conservative Party's 331 seats by percentage of majority.

### Other parties

All five parties' candidates achieved more than deposit-retaining threshold of 5% of the vote in 2015, reflecting frequent such results for the Green Party and UKIP in that election. Liberal Democrat or predecessor-party Liberal candidates were second-placed between February 1974 and 2010 (inclusive). The closest contest for Henley was in 1966, when Labour's George Cunningham took 44.6% of the vote in a two-candidate contest.

### Turnout

At general elections, turnout in the constituency has ranged between 52.9% in the "khaki election" of 1918 to 81.7% in 1950.
