After emerging as the largest party in the Senedd (Welsh Parliament) election, Plaid Cymru is now establishing itself as the next Welsh government. It’s the first administration not led by Welsh Labour since devolution began 27 years ago.
For UK Labour, Plaid’s breakthrough could become one of the most significant constitutional and political challenges of the coming years.
The clearest guide to Plaid’s immediate priorities is its “first 100 days” programme for government. This was published during its February 2026 conference. It includes calls for a new devolution bill to be passed in the UK parliament giving Wales the same devolved powers as Scotland and new funding arrangements for Wales.
