Opinion polls How people in Wales have said they would vote in a Senedd election, poll by poll, with the results of the 2021 and 2026 elections to compare them with.
The latest poll More in Common for Cavendish Cymru, Senedd Sources. 24 to 30 September 2026.
Plaid 32% −3 Reform 27% −2 Labour 18% +7 Conservative 12% +1 Green 6% −1 Lib Dem 5% +1 Changes are in percentage points since the election on 7 May 2026.
Until 2021 everyone had two votes in a Senedd election: one for a constituency Member and one for a party's regional list. Under the Senedd Cymru (Members and Elections) Act 2024 there is a single vote, for a party list or an independent candidate, in each of 16 constituencies that elect six Members. Polls up to September 2023 asked about the two old votes and polls from June 2024 ask about the single vote, so the two sets are shown separately.
A poll is a snapshot of what a sample of people said when it was taken. Every figure has a margin of error of a few points either way, so a small change between two polls may mean nothing. Pollsters also word their questions and weight their samples differently.

Diamonds mark the election results. Lines join one poll to the next and stop at each change of system and at the election. Also in the tables but not drawn: Abolish the Welsh Assembly.
Polls on the single vote Newest first. The 7 May 2026 row is the election result.
A blank cell means the source didn't publish that party's figure in a form we could check. Smaller parties and others are left out, so rows don't add up to 100. The leading party in each row is in bold.

About these figures We list a poll only when we could check its figures against the pollster's own tables or release, the client's release, or a news report of the release. Polls we could not check are left out. An MRP model estimates the result in every constituency from a large sample. Its all-Wales figures are the model's central estimate, and we give no sample size unless the pollster published an exact one. Election results are shares of the valid votes cast. The 2021 result appears twice: the regional list vote with the list polls and the constituency vote with the constituency figures. Every row links to the source we checked it against.
