Southampton City Council consists of 16 electoral wards, each returning three councillors. Labour has controlled the council twice - from 1997-2000 and since 2012. The Conservatives had control between 2008-2012. There were eight years of no overall control in the noughties, during which Labour ran a minority administration for two years, followed by the Lib Dems for four years, followed by the Tories for two. The Lib Dems lost their last council seats in 2014, due in large part to their role in the coalition government.
The last time a party won all the Parliamentary seats in Southampton was following the 1987 general election when the Tories won a clean sweep. At this time the seat of Romsey did not include any Southampton territory, but boundary changes in 1997 took in one Southampton council ward. Further boundary changes in 2010 took in another Southampton council ward and it was re-named Romsey and Southampton North.
The constituencies of Test and Itchen are named after the two major rivers that meet here.
Southampton returned a Leave vote in 2016, although the Labour member for Test opposed the triggering of Article 50. His constituency returned a narrow 50.59% Remain vote. Leave voting Itchen is currently held by the Conservatives with one of the smallest majorities in the UK at just 31 votes. None of these seats are expected to change hands at this election.
