CLAIMED · NOT VERIFIED BY US
Every figure on this page is the Plaid Cymru's own. The party states them; this site records that they were stated, when, and where. Nothing here has been counted, audited, or confirmed by partytracker.uk, and no figure should be read as our estimate of the party's membership.
That is not a caveat about this site's thoroughness. No independent count of British party membership exists: no regulator audits it, and no filing discloses it. Every membership number in public circulation — for any party — originates with that party. The most a record can honestly do is attribute it and date it.
Figures are listed newest first. Change is the difference between consecutive claims, so it inherits their status: it is the movement between two things the party said, not a measured change in membership, and the gaps between rows are not uniform.
Where a claim is worded imprecisely, the wording is reproduced verbatim alongside the number. A source that says “270k+” is not a source that says 270,000, and rendering it as the latter would manufacture a precision the party never offered.
A row marked DISPUTED carries a second link to whoever disputed it. The label records that a public contest exists, not that this site has taken a side in it.
No membership claim recorded.
Nothing is shown here until it comes from a source that can be linked. A placeholder figure on this page would be precisely the failure the project exists to avoid.
