List of Parliamentary constituencies in Gwynedd
There are four constituencies covering the preserved county of Gwynedd. They are all county constituencies (CCs) of the House of Commons of the Parliament of the United Kingdom (Westminster), and are used also 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.[1]
The preserved county of Gwynedd shares its name with the principal area of Gwynedd, although the preserved county also covers Anglesey.
For Welsh Assembly elections, constituencies are grouped into additional member electoral regions, and changes to constituency boundaries mean, also, changes to regional boundaries.
