Vauxhall was wholly within the London Borough of Lambeth. The core of the constituency, unchanged from the former Lambeth North, was delimited by the River Thames to the west and north and the boundary with Southwark to the east.
At just over 6% of the population, Vauxhall (which was located in the London Borough of Lambeth) had the largest proportion of LGBT+ people in the country as of 2016.[3]
Since a 1989 by-election, the seat had been represented by Kate Hoey. Continuing a history as a safe seat for Labour, since her 1989 election, Hoey consistently achieved majorities of 9,100 to 20,200 votes. The 2015 result made the seat the 105th safest of Labour's 232 seats by percentage of majority.[4]
Despite Hoey being a prominent campaigner for leaving the European Union, Vauxhall voted to remain in the EU by 77.6% in the national referendum on 23 June 2016.[5] This made it the strongest pro-EU constituency to be represented by a pro-Brexit MP. In the 2017 general election, this led to her seat being targeted by pro-Remain organisations and high-profile individuals seeking to oust her in favour of the pro-EU Liberal Democrat candidate.[6] There had been a change.org petition calling for Hoey's deselection as the Labour candidate for the seat; however, due to party rules this was unsuccessful.[7][8] In the 2017 election, Hoey significantly increased her majority to the largest the seat had ever seen; the Liberal Democrat vote total more than trebled, and they moved back into second place having fallen to fourth behind the Conservatives and the Greens in 2015. In May 2018, Hoey's local party passed a vote of no confidence in her, vowing to deselect the MP as well.[9] On 8 July 2019 Hoey announced that she would retire from the House of Commons, and would not seek re-election as a Labour candidate at the next general election.[10]
The constituency shared boundaries with the Vauxhall electoral division for election of councillors to the Greater London Council at elections in 1973, 1977 and 1981.
Three Liberal Democrat councillors represented the Bishop's ward from 1990 to 2014; they subsequently lost the three ward seats to Labour, as did the sole Liberal Democrat councilors in the Oval and Vassall wards. They failed to gain them back in 2018.
At the 2018 council elections, Labour won all of the ward seats in the constituency. The Liberal Democrats finished second in the wards of Bishop's, Oval, Stockwell and Prince's. The Conservatives finished the runner up in Clapham Town and the Green Party in Vassall, Ferndale and Larkhall.
13.6% was the largest vote share increase in a Labour held seat for the Liberal Democrats at the 2017 general election.[16]UKIP stood down their candidate in order to ensure Hoey was re-elected.[17]
