List of political parties in Wales

The Parliament of the United Kingdom is a legislative body in the United Kingdom and creates primary legislation.^[1] There are two chambers within the Parliament of the United Kingdom: the House of Commons (the elected chamber) and the House of Lords. This article focuses on the House of Commons. Three parties have elected representatives in that house (MPs): Welsh Labour, Welsh Conservatives and Plaid Cymru. The constituencies are due to change for the 2024 general election.^[2]

The Senedd was formed under the Government of Wales Act 1998, by the Labour government, following a referendum in 1997. It was given greater powers under the 2011 Welsh devolution referendum. In 2021, four parties have elected representatives in the Senedd: Welsh Labour, Welsh Conservatives, Plaid Cymru and Welsh Liberal Democrats.
