Beaconsfield (UK Parliament constituency)

Beaconsfield is a constituency in Buckinghamshire represented in the House of Commons of the UK Parliament since 2019 by Joy Morrissey of the Conservative Party. She succeeded Independent and former Conservative Dominic Grieve, whom she defeated following his suspension from the party. The constituency was established for the February 1974 general election.

History
The constituency was created in 1974, mostly from the former seat of South Buckinghamshire, since which date the area has formed the southernmost part of Buckinghamshire — before 1974 the notable settlements of Slough and Eton, as well as less well-known Langley, Wraysbury, Sunnymeads and Datchet were in the county.

This leads to the shape of the constituency, further accentuated in irregularity by the Thames meander containing Cookham, Berkshire to the west and southwest.

1982 by-election candidates
In the 1982 Beaconsfield by-election caused by the death of Sir Ronald Bell, the third-placed candidate was Tony Blair for the Labour Party. Conservative Tim Smith was the first and only person ever to have beaten Blair in an election and won; Liberal Paul Tyler was in second place. Tyler later became an MP for North Cornwall, meaning that, most unusually, the three main-party candidates subsequently served in the House of Commons at the same time.

2010 election
Incumbent Dominic Grieve's win in 2010, with 61.1% of the vote, was the second highest share of the vote in the general election for a Conservative candidate after William Hague in Richmond (Yorks).

2016 EU referendum
Beaconsfield is estimated to have voted 51% remain in the 2016 referendum on the UK's membership of the EU. Although estimates of the constituency results have not been confirmed, the official UK Electoral Commission EU referendum results detail the area of South Buckinghamshire, which contains the Beaconsfield constituency, as voting to leave the EU with a percentage of 50.7%.
