Swansea East (UK Parliament constituency)

Swansea East (Dwyrain Abertawe) was a borough constituency in Wales in the House of Commons of the Parliament of the United Kingdom. It was represented by members of the Labour Party from 1922 until 2024.

As part of the 2023 Periodic Review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales, the seat was abolished. Its wards were split between Neath and Swansea East, and Swansea West, to be first contested at the 2024 general election.

Constituency profile
Although the constituency voted strongly to leave the European Union in 2016, an analysis of YouGov polling by Focaldata suggested support for Remain had risen from 37.9% to 50.7% in August 2018. However, in the 2019 European elections the city of Swansea as a whole voted strongly for the Brexit Party.
