Caerphilly by-election: 23 October 2025
Plaid Cymru has chosen a true local champion—Lindsay Whittle—to contest the upcoming Caerphilly Senedd by-election and represent the community he’s proudly served for decades.
Born and bred in Caerphilly, Lindsay has spent his life fighting for local people on the Council and in the community. He came a close second in last year’s Westminster election, and with strong local support is favoured by many to win the Caerphilly Senedd seat.
“I have a proud record of standing up for Caerphilly, and Plaid Cymru is the only party truly standing up for Wales.”
— Lindsay Whittle
Plaid Cymru leader Rhun ap Iorwerth is backing Lindsay to be a bold, principled voice in the Senedd—someone who will always put Caerphilly first.

Why Lindsay?
- ✅ Deep roots in Caerphilly
- ✅ Proven record of delivery on local issues
- ✅ Trusted by the community
- ✅ Ready to take on Labour and Reform
Labour has taken Caerphilly for granted. From Starmer’s broken promises to Welsh Labour’s NHS failures and the council's cuts to libraries and public services, it’s time for change.
Plaid Cymru is the only party with the strength and vision to challenge both Labour and Reform—and Lindsay Whittle is the candidate to do it.
