Clwyd (constituency)

The constituency encompasses western Flintshire, including Mold and Holywell, and the west and north of Denbighshire including Rhyl, Prestatyn, St Asaph, Denbigh, Ruthin, and Llangollen. It also includes Abergele, Colwyn Bay, and Rhos-on-Sea from Conwy County Borough, and the far south-east includes the village of Trevor in Wrexham County Borough.

A Senedd constituency comprising the boundaries of the UK Parliament constituencies of Clwyd East and Clwyd North, has been proposed by the Democracy and Boundary Commission Cymru for the 2026 election to the Senedd (Welsh Parliament; Senedd Cymru). It was initially proposed in September 2024,^[2] but was unchanged in the December proposals as most other constituencies adopted Welsh-only names.^[3] The name and boundaries were confirmed in the commission's final recommendations in March 2025.^[4] When announcing their candidates, Reform UK used "Clwyd East, Clwyd North" instead, using the English names for the pair of UK Parliament constituencies that form it.^[5]

The constituency was established in 2026, following the passing of the Senedd Cymru (Members and Elections) Act 2024. The act legislates electoral reform of the Senedd to create 16 larger "super constituencies", pairing the 32 UK Parliament constituencies in Wales, and using a new fully proportional voting system, with each constituency electing six Members of the Senedd (MSs) rather than one previously.^[2]
