What is the Senedd by-election in Caerphilly?

People in Caerphilly will vote for a new representative in the Welsh Parliament after the sudden death of the area's Member of the Senedd (MS), Labour's Hefin David in August.

On 23 October voters in Caerphilly will decide who will be their MS for the next six months.

It will fill a vacancy until May 2026 when another election will decide the make-up of the newly expanded Welsh Parliament.

BBC Wales' Terel Edmunds tells us more.
