Blaenau Gwent Caerffili Rhymni
constituency of the Senedd
Blaenau Gwent Caerffili Rhymni (Welsh for 'Blaenau Gwent, Caerphilly, [and] Rhymney'; ) is a six-member constituency of the Senedd (Welsh Parliament; Welsh: Senedd Cymru) used in the 2026 Senedd election. It covers areas in the south-east of Wales, particularly parts of Blaenau Gwent and Caerphilly.
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, but was renamed to Blaenau Gwent Caerffili Rhymni in December proposals with most constituencies using Welsh-only names. The Welsh-only name and boundaries were confirmed in the commission's final recommendations in March 2025. 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.
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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Blaenau Gwent Caerffili Rhymni”, the useful work is to connect “constituency of the Senedd” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 26, 2026. The linked authority identifier is Q133539753. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2026, 2024 and 2025.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
