Old Bexley and Sidcup
Template:Short description Template:Use dmy dates Template:Infobox UK constituency main
Old Bexley and Sidcup is a constituency in Greater London represented in the House of Commons of the UK Parliament since its 1983 creation. Its first Member of Parliament (MP) was former Prime Minister Edward Heath, who previously represented Bexley (1950–1974) and Sidcup (1974–1983). The seat has been held since a 2021 by-election by Louie French of the Conservative Party, following the death of incumbent James Brokenshire. Template:TOC limit
History and profile
The seat was created in 1983 by combining a small part of the abolished seat of Bexleyheath, chiefly Old Bexley, with the abolished seat of Sidcup.
On 29 January 2008 the Conservative Party withdrew the whip from the constituency's MP, Derek Conway, following alleged misuse of funds revealed by the MPs expenses controversy, who declined to resign as MP and became an Independent. He retired from national politics in 2010.
Sir Edward Heath (Prime Minister of the United Kingdom 1970–1974) held this area (also referring to its main predecessor seats, Bexley and Sidcup) from 1950 until 2001 when he retired at the age of 84, at the time the longest-serving MP in the Commons, known as the Father of the House.
- Political overview
The seat has been won at general elections since creation by the Conservative Party candidate. The 1997 New Labour landslide saw the party's majority fall to its lowest level of 7% of the vote. Its greatest level has to date been 41.5% of the vote — in 1987.
In 2010 the seat was won by the Conservative candidate James Brokenshire, who had transferred to this seat and approved by his local party when his former seat of Hornchurch was abolished in boundary changes. His 2015 result made the seat the 105th safest of the Conservative Party's 331 seats by percentage of majority.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The seat was left vacant following Brokenshire's death on 7 October 2021.<ref>Template:Cite news</ref><ref>Template:Cite tweet</ref> until a by-election was held on 2 December which resulted in a Conservative hold.
Boundaries
Historic
1983–1997: The London Borough of Bexley wards of Blackfen, Blendon and Penhill, Cray, Lamorbey, St Mary's, Sidcup East, and Sidcup West.
1997–2010: The London Borough of Bexley wards of Blackfen, Blendon and Penhill, Cray, Danson, East Wickham, Falconwood, Lamorbey, St Mary's, Sidcup East, and Sidcup West.
2010–2024: The London Borough of Bexley wards of Blackfen and Lamorbey, Blendon and Penhill, East Wickham, Falconwood and Welling, Longlands, St Mary's, and Sidcup.
As its name suggests, the seat covers the Bexley and Sidcup areas; it formerly included Danson Park which owing to more development in the south was moved to the Bexleyheath and Crayford constituency.
Current

Further to the 2023 periodic review of Westminster constituencies, which came into effect for the 2024 general election, the constituency is composed of:
- The London Borough of Bexley wards of: Blackfen & Lamorbey; Blendon & Penhill; East Wickham; Falconwood & Welling; Longlands; St. Mary’s & St. James; Sidcup.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web }}</ref>
The revised contents take into account the local government boundary review for Bexley which became effective in May 2018. Boundaries were extended slightly by adding the parts of the expanded East Wickham and Falconwood & Welling wards previously in Bexleyheath and Crayford.
