Portsmouth South is a constituency[n 1] represented in the House of Commons of the UK Parliament since 2017 by Stephen Morgan of the Labour Party.

[2] Notwithstanding this, following the Second World War the city has a large proportion of flats, increasingly in a more aesthetic apartment style, some being affordable social housing and brutalist tower blocks; however, the majority of the city is of semi-detached and terraced nature with a mixture of incomes centred around the national average[3] and excellent amenities.

During the 2010 general election campaign, independent candidate Les Cummings distributed a leaflet claiming that sitting MP Mike Hancock was a paedophile, which was later proven in court to be false.

Cummings was subsequently convicted under the Representation of the People Act 1983 for distributing material which was known to be false with the intention of smearing or defaming to affect the return of a Member of Parliament, and was fined £500 as a result.

[5] Morgan's vote share remained steady in the 2024 election, with the Conservatives falling significantly behind both Labour and Reform.
