It was proposed following the 2026 review of Senedd constituencies, and is a pairing of the two UK Parliament constituencies of Blaenau Gwent and Rhymney and Caerphilly. It has a Welsh-only name.
Boundaries
A Senedd constituency comprising the boundaries of the UK Parliament constituencies of Blaenau Gwent and Rhymney and Caerphilly, 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 using the English name Blaenau Gwent, Rhymney and Caerphilly in September 2024,[2] but was renamed to Blaenau Gwent Caerffili Rhymni in December proposals with most constituencies using Welsh-only names.[3] The Welsh-only name and boundaries were confirmed in the commission's final recommendations in March 2025.[4] When announcing their candidates, Reform UK used "Blaenau Gwent and Rhymney, Caerphilly" instead, using the English names for the pair of UK Parliament constituencies that form it.[5]
It encompasses entirely the principal area (county borough) of Blaenau Gwent and parts of Caerphilly County Borough in South Wales. 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]
