Senedd Cymru/ Welsh Parliament elections 2026
Elections to the Senedd Cymru/ Welsh Parliament took place on 7 May 2026. Plaid Cymru won the most seats, followed by Reform UK Wales. This election was the first since devolution in Wales where the Labour party did not win the most seats.
This was also the first election since a new voting system was introduced in Wales. Under this system, 16 constituencies elect six Members of the Senedd each.
The dashboard below presents national results data, results by party, and results by constituency. It also includes data on turnout.
