THE number of MPs in Wales will be cut from 40 to 32 at the next General Election – and the Cardiff South and Penarth constituency has been reorganised as part of the overhaul.

The Boundary Commission for Wales has revealed the new Parliamentary constituency boundaries for Wales, which will take effect at the next General Election.

The Cardiff South and Penarth constituency remains, but its boundaries have been redrawn.

Cathays, previously in Cardiff Central, and Dinas Powys, previously in the Vale of Glamorgan, have been moved into the Cardiff South and Penarth constituency.

Meanwhile Llanrumney, Rumney, and Trowbridge have been moved from Cardiff South and Penarth into Cardiff East.

Butetown, Corneswell, Grangetown, Llandough, Plymouth, Splott, St Augustine’s. Stanwell, and Sully remain in Cardiff South and Penarth.

A date has not been set for the next General Election, although it must be held by January 28, 2025.

The plans will not impact Welsh Parliament constituencies, which will remain unchanged.

The commission's secretary Shereen Williams said: "It is our firm belief that these recommendations represent the best way to create 32 constituencies in Wales (...), including taking account of geography and local ties.

"Though managing a significant reduction in the number of constituencies is never an easy task for a Boundary Commission, it has been made significantly easier thanks to the number and quality of representations we have received from the public, from Members of Parliament, from political parties, and from Principal Councils across Wales.

"The commission would like to put on record its thanks to everyone who took part in the Review and strengthened the recommendations."
