A
Senedd constituency comprising the boundaries of the
UK Parliament constituencies of
Newport East and
Newport West and Islwyn, has been proposed by the
Democracy and Boundary Commission Cymru for the
2026 election to the
Senedd (Welsh Parliament; ). It was initially proposed using the name
Newport and Islwyn in September 2024, The
Welsh-only name and boundaries were confirmed in the commission's final recommendations in March 2025. When announcing their candidates,
Reform UK used "Newport East, Newport West and Islwyn" instead, using the English names for the pair of UK Parliament constituencies that form it. It encompasses the entire of the
principal area (county borough) of
Newport 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. == Elections ==
