Introduction

We plan to strengthen democracy by creating a more effective and representative Welsh Parliament.

The Senedd Cymru (Members and Elections) Act 2024

The Senedd Cymru (Members and Elections) Act sets out our plans to create a Welsh Parliament that can better serve people in Wales. The Act, which officially passed into law on 24 June 2024 reflects how the role and responsibilities of the Senedd have changed since the National Assembly for Wales first opened its doors in 1999.

The Senedd can now make laws and set Welsh taxes – these are decisions which affect the lives of every single person in Wales.

But while the Senedd gained responsibilities, its capacity stayed the same, making it the smallest legislature in the UK with 60 members compared to 129 in the Scottish Parliament, and 90 in the Northern Ireland Assembly.

Changes brought about by the Senedd Cymru (Members and Elections) Act

On 8 May 2024, Members of the Senedd voted to:

  • increase the size of the Senedd to 96 Members.
  • change the electoral system to one fully based on the principle of proportional representation, with names of all candidates on the ballot paper. From the 2026 Senedd election, the D’Hondt formula will be used (this formula has been used to determine the Senedd’s regional list Members (Senedd reform: a glossary on Senedd Cymru).
  • make 16 new Senedd constituencies (2026 Review: Final Determinations on Democracy and Boundary Commission Cymru), which will be created by pairing the 32 UK Parliamentary constituencies, in time for the 2026 Senedd election. There will be a full boundary review after the 2026 Senedd election
  • have 6 Members of the Senedd elected, from closed lists, in each of the 16 constituencies.
  • increase the limit on the number of Welsh Ministers who can be appointed from 12 to 17 (plus the First Minister and the Counsel General) with the ability to further increase the number to 18 or 19 with the Senedd’s approval.
  • give Members of the Senedd the flexibility to elect a second Deputy Presiding Officer.
  • make it law that all candidates for Senedd elections and Members of the Senedd are resident in Wales.
  • hold Senedd elections every 4 years from 2026 onwards.

The Act is based on the recommendations of the Special Purpose Committee on Senedd Reform (Reforming our Senedd: A stronger voice for the people of Wales on Senedd Cymru). These recommendations were supported by a majority of Senedd Members in June 2022.

Next steps

  • Work is now underway to ensure the changes brought about by the Senedd Cymru (Members and Elections) Act will be in place for the 2026 Senedd election.

Diversity and inclusion guidance for political parties

The Welsh Government has published voluntary guidance aimed at helping political parties to improve diversity among candidates standing for Welsh elections. 

Published following a public consultation, the guidance encourages political parties to:

  • develop, publish, implement, and regularly review diversity and inclusion strategies for Welsh elections (Part 1)
  • voluntarily collect and publish diversity information about their candidates for Senedd elections (Part 2)
  • consider steps they may take in relation to voluntary quotas for women (Part 3)

The guidance will be kept under review and revised as appropriate to maximise its impact and effectiveness.

We have created a short animated video which summarises the main aims of the guidance.
