Enfield Southgate (UK Parliament constituency)

Enfield Southgate is a constituency in the House of Commons of the UK Parliament. It was created in 1950, and has been represented since 2017 by Bambos Charalambous, a member of the Labour Party.
History.
From 1950 to the 1983 general election, this constituency was known as Southgate. The prefix of the seat's London Borough was added in 1974.
The seat gained national attention in the 1997 general election when Michael Portillo, Secretary of State for Defence was unexpectedly defeated on a massive swing - the 'Portillo moment'. Portillo had been widely expected to contest the Conservative leadership and his defeat the media took to epitomise the Labour landslide victory. The victorious candidate, Stephen Twigg, increased his majority at the following election. In the 2005 general election, Twigg's majority was the largest overturned, with a swing of 8.7% to the Conservative candidate David Burrowes.
The 2015 result gave the seat the 60th most marginal majority of the Conservative Party's 331 seats by percentage of majority, with Labour gaining the seat in the 2017 general election on a substantial 9.7% swing. 
Enfield Southgate is one of five constituencies, the others being Croydon Central, Leeds North West, Peterborough and Reading East, which elected Labour MPs in 2017 having not done so since 2001. Bambos Charalambous in 2019 became the first Labour MP in Enfield Southgate to be re-elected with a reduced share of the vote.
Constituency profile.
The constituency is in the west of the London Borough of Enfield and generally more affluent than other parts of the borough. It is more cosmopolitan than many other London suburban constituencies which are or have been Conservative-held, including sizeable Jewish, Muslim and Cypriot communities.
In recent years, the south-eastern and southern wards of the constituency including Bowes and Palmers Green always return Labour local councillors, with some councillors also in Southgate Green and Winchmore Hill. These wards tend to give the bulk of the Labour vote. However, the remaining wards generally elect Conservative councillors.
To the north, the seat becomes semi-rural as it takes in Trent Park and the former campus of Middlesex University, and the Cockfosters terminus of the Piccadilly line, stretching into the wealthy Hadley Wood area. Some areas (smaller than local government wards) in the south of the constituency have middle rankings of deprivation when placed in a complete list of wards (such as the 2000 Index of Multiple Deprivation), however all other output areas lack any significant deprivation.
