Caerphilly (UK Parliament constituency)

Caerphilly (Welsh: Caerffili) is a constituency centred on the town of Caerphilly in South Wales, represented in the House of Commons of the UK Parliament since 2001 by Wayne David of the Labour Party.

Since its creation, the constituency has always elected Labour MPs, although the predecessor constituency of East Glamorganshire, and prior to that Glamorganshire had elected Liberal MPs throughout the Victorian era.

The constituency is to retain its name but its boundaries altered, as part of the 2023 Periodic Review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales for the next United Kingdom general election.
