Dyfed constituencies
Five constituencies cover Dyfed, also used for elections to the National Assembly for Wales. The current boundaries have been effective since the Welsh Assembly election, 2007 and the 2010 United Kingdom general election.
Dyfed is one of the eight preserved counties of Wales, consisting of the principal areas of Pembrokeshire, Carmarthenshire and Ceredigion. These principal areas are also known as counties.
For Welsh Assembly elections, constituencies are grouped into additional member electoral regions.
As part of the Sixth Periodic Review of Westminster constituencies the Boundary Commission for Wales proposed changes to almost all the existing Welsh Westminster constituencies, giving some of them Welsh language names.
The Mid and West Wales region also includes two Powys constituencies and one Gwynedd constituency.
