List of Parliamentary constituencies in Gwynedd

Three constituencies cover the preserved county of Gwynedd for the House of Commons of the UK Parliament (Westminster), and are used also for elections to the Senedd. The current boundaries have been effective since the 2007 National Assembly for Wales election and the 2010 United Kingdom general election.[1][n 1].

The preserved county of Gwynedd shares its name with the southern bulk, the principal area, Gwynedd, Anglesey (Welsh: Ynys Môn), forms a second principal area, i.e. has its own local government council.

For Senedd elections, the constituencies each elect one assembly member and are grouped into additional-member electoral regions, in this instance the region is North Wales.

Proposed boundary changes

The Boundary Commission for Wales submitted their final proposals in respect of the Sixth Periodic Review of Westminster Constituencies (the 2018 review) in September 2018. Although the proposals were immediately laid before Parliament they were not brought forward by the Government for approval. Accordingly, they did not come into effect for the 2019 election which took place on 12 December 2019, and which was contested using the constituency boundaries in place since 2010.

Under the terms of the Parliamentary Voting System and Constituencies Act 2011, the Sixth Review was based on reducing the total number of MPs from 650 to 600 and a strict electoral parity requirement that the electorate of all constituencies should be within a range of 5% either side of the electoral quota.

On 24 March 2020, the Minister of State for the Cabinet Office, Chloe Smith, issued a written statement to Parliament setting out the Government's thinking with regard to parliamentary boundaries. They propose to bring forward primary legislation to remove the statutory obligation to implement the 2018 Boundary Review recommendations, as well as set the framework for future boundary reviews in time for the next review which is due to begin in early 2021 and report no later than October 2023. It is proposed that the number of constituencies now remains at the current level of 650, rather than being reduced to 600, while retaining the requirement that the electorate should be no more than +/- 5% from the electoral quota.[2]
