Counting begins in Caerphilly as by-election votes are tallied

Counting is now underway in Caerphilly following the close of polls at 10pm, as voters wait to see who will take the vacant Senedd Cymru seat.

Voters across the constituency headed to the polls throughout Thursday, 23 October to choose from eight candidates competing in what has been described as one of the most significant by-elections in the 26 years of Welsh devolution.

Those standing are:

• Liberal Democrats: Steve Aicheler
• Gwlad: Anthony Cook
• Greens: Gareth Hughes
• Conservatives: Gareth Potter
• Reform: Llyr Powell
• UKIP: Roger Quilliam
• Labour: Richard Tunnicliffe
• Plaid Cymru: Lindsay Whittle

The by-election was called following the death of Hefin David, who had represented Caerphilly in the Senedd since 2016. Labour has held the seat since devolution in 1999, making this contest an important test for the party ahead of the 2026 Senedd election.

If Labour lose the seat, it could prove to be a major political shift just six months before voters across Wales return to the polls for the national election.

Party leaders, including Plaid Cymru’s Rhun ap Iorwerth and Reform UK’s Nigel Farage, visited Caerphilly on Thursday to support their candidates in the final hours of campaigning.

The outcome of the by-election could have a direct impact on the balance of power in the Senedd. Before Hefin David’s passing, Labour held 30 of the 60 seats, relying on at least one opposition member to pass legislation and spending plans.

A Labour victory tonight would maintain that position, but a loss would mean the party would need the support of two opposition members to secure key votes.
