The constituency was abolished following boundary changes for the 2007 Assembly elections.
The other seven constituencies of the region were Brecon and Radnorshire, Carmarthen East and Dinefwr, Carmarthen West and South Pembrokeshire, Ceredigion, Llanelli, Montgomeryshire and Preseli Pembrokeshire.
In elections for the National Assembly for Wales, each voter has two votes.
