BBC Radio Cymru

BBC Radio Cymru is the BBC's Welsh-language radio station, broadcasting news, current affairs, sport, and entertainment primarily in Welsh. It is the flagship Welsh-language radio output of BBC Cymru Wales and serves as a primary political information source for Welsh-speaking audiences.

During the 2026 Senedd election campaign, BBC Radio Cymru co-broadcast 'Y Ddadl Fawr' (the Big Debate) on 23 April 2026 alongside S4C — a major Welsh-language leaders debate featuring all major Senedd parties. The debate exposed how immigration dominated discussion despite the Senedd having no immigration powers, a paradox that highlighted the difficulty of separating Welsh devolved politics from Westminster-dominated national discourse.

BBC Radio Cymru broadcasts on FM and DAB across Wales and provides election-night coverage, leaders' interviews, and campaign analysis in Welsh. Its audience is largely concentrated in Welsh-speaking communities in north and west Wales, where it has particular political salience.
