Old Bexley and Sidcup is aconstituency inGreater London represented in theHouse of Commons of theUK Parliament since its1983 creation. Its firstMember of Parliament (MP) was former Prime MinisterEdward Heath, who previously representedBexley (1950–1974) andSidcup (1974–1983). The seat has been held since a2021 by-election byLouie French of theConservative Party, following the death of incumbentJames Brokenshire.
The seat was created in 1983 by combining a small part of the abolished seat ofBexleyheath, chiefly Old Bexley, with the abolished seat ofSidcup.
On 29 January 2008 theConservative Partywithdrew the whip from the constituency's MP,Derek Conway, following alleged misuse of funds revealed by theMPs 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 theFather of the House.
The seat has been won at general elections since creation by theConservative Party candidate. The1997 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 candidateJames Brokenshire, who had transferred to this seat and approved by his local party when his former seat ofHornchurch 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.[2] The seat was left vacant following Brokenshire's death on 7 October 2021.[3][4] until aby-election was held on 2 December which resulted in a Conservative hold.
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 theBexleyheath and Crayford constituency.

Further to the2023 periodic review of Westminster constituencies, which came into effect for the2024 general election, the constituency is composed of:
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 inBexleyheath and Crayford.
Old Bexley and Sidcup has average incomes among the highest of all constituencies,[6] a high proportion of semi-detached and detached homes[7] and low unemployment[8] with a lower than average dependency onsocial housing.[6]
The constituency generally consists of middle-class and lower middle-class outer Londonsuburbia, served by theDartford Loop andBexleyheath commuter railway lines toCentral London. Sidcup has been largely developed to neatgarden suburb-inspired building schemes for most homes.
