Carmarthen East and Dinefwr (Senedd constituency)
Senedd constituency (1999–2026)
From Wikipedia, the free encyclopedia
Carmarthen East and Dinefwr (Welsh: Dwyrain Caerfyrddin a Dinefwr) was a constituency of the Senedd. It elected one Member of the Senedd by the first past the post method of election. It was one of eight constituencies in the Mid and West Wales electoral region, which elected four additional members, in addition to eight constituency members, to produce a degree of proportional representation for the region as a whole.

Boundaries
1999 to 2007
The constituency was created for the first election to the Assembly, in 1999, with the name and boundaries of the Carmarthen East and Dinefwr Westminster constituency. It was a Dyfed constituency, one of five constituencies covering, and entirely within, the preserved county of Dyfed.
The other four Dyfed constituencies were Carmarthen West and South Pembrokeshire, Ceredigion, Llanelli and Preseli Pembrokeshire. They were all within the Mid and West Wales electoral region.
The region consisted of the eight constituencies of Brecon and Radnorshire, Carmarthen East and Dinefwr, Carmarthen West and South Pembrokeshire, Ceredigion, Llanelli, Meirionnydd Nant Conwy, Montgomeryshire and Preseli Pembrokeshire.
From 2007
The constituency included the whole of 41 Carmarthenshire communities (Abergwili; Ammanford; Betws; Cenarth; Cilycwm; Cwmamman; Cynwyl Gaeo; Dyffryn Cennen; Gorslas; Llanarthney; Llanddarog; Llanddeusant; Llandeilo; Llandovery; Llandybie; Llandyfaelog; Llanegwad; Llanfair-ar-y-bryn; Llanfihangel Aberbythych; Llanfihangel-ar-Arth; Llanfihangel Rhos-y-Corn; Llanfynydd; Llangadog; Llangathen; Llangeler; Llangunnor; Llangyndeyrn; Llanllawddog; Llanllwni; Llansadwrn; Llansawel; Llanwrda; Llanybydder; Llanycrwys; Manordeilo and Salem; Myddfai; Newcastle Emlyn; Pencarreg; Quarter Bach; St Ishmael; Talley).
Boundaries changed for the 2007 Assembly election. Carmarthen East and Dinefwr remains one of five Dyfed constituencies and one of eight constituencies in the Mid and West Wales region. However, boundaries within Dyfed changed, to realign them with local government ward boundaries and to reduce the disparities in the sizes of constituency electorates, and the boundaries of the region changed, to align them with the boundaries of preserved counties.
The other four Dyfed constituencies were, again, Carmarthen West and South Pembrokeshire, Ceredigion, Llanelli and Preseli Pembrokeshire, all within the Mid and West Wales electoral region.
The region consisted of the constituencies of Brecon and Radnorshire, Carmarthen East and Dinefwr, Carmarthen West and South Pembrokeshire, Ceredigion, Dwyfor Meirionnydd, Llanelli, Montgomeryshire and Preseli Pembrokeshire.
For Westminster purposes, the same new constituency boundaries became effective for the 2010 United Kingdom general election.
Voting
In general elections for the Senedd, each voter had two votes. The first vote was used to vote for a candidate to become the Member of the Senedd for the voter's constituency, elected by the first past the post system. The second vote was used to vote for a regional closed party list of candidates. Additional member seats were allocated from the lists by the d'Hondt method, with constituency results being taken into account in the allocation.
