Reject Reform in Cymru

As Reform UK rose in Welsh polls to challenge for first place in the 2026 Senedd election, a counter-movement emerged among progressives who feared that a Reform-led or Reform-influenced government would undermine the devolution settlement. Reject Reform in Cymru was established to coordinate this response across party lines.

Reject Reform in Cymru represents the defensive dimension of the pro-devolution movement — a response to the specific electoral threat posed by Reform UK rather than a positive campaign for expanded powers. The group's messaging frames the 2026 election as an existential moment for devolution, arguing that Reform's strategic ambiguity on the Senedd's future (combined with its base's clear abolitionist sentiment) makes it a threat to the very institutions of Welsh self-governance. By mobilising progressives across party lines — Labour, Plaid, Liberal Democrat, and Green supporters — the campaign attempts to create a 'progressive bloc' united by a shared commitment to defending the Senedd. This cross-party framing is strategically significant because it mirrors the anti-independence campaigns in Scotland ('Better Together') but in reverse: here, it is devolution's defenders who must unite against a populist threat. The campaign's effectiveness depends on whether the shared threat of Reform is sufficient to overcome the deep rivalries between Welsh Labour and Plaid Cymru.
