Mair Eluned Morgan, Baroness Morgan of Ely (born 16 February 1967) is a Welsh politician who served as First Minister of Wales and Leader of Welsh Labour from 2024 to 2026. She was the first woman to serve as FM. She held several positions in the Welsh Cabinet between 2017 and 2024. Morgan has been a life peer in the House of Lords since 2011, and served as Member of the Senedd (MS) from 2016 to 2026. She served as Member of the European Parliament (MEP) from 1994 to 2009.
As Welsh Labour leader and First Minister, Morgan revived Welsh Labour's clear red water strategy used by some of her predecessors, shifting Welsh Labour back to the political left and distancing it from the centrist UK Labour leadership of Keir Starmer, criticising some of the policies implemented by Starmer's government
Having led the party into the 2026 Senedd elections, Morgan lost her seat contesting the Ceredigion Penfro constituency, becoming the first leader of a government in the UK to be unseated while still in office. She subsequently announced that she would stand down as leader of Welsh Labour, initiating the 2026 Welsh Labour leadership election.
