The Boundary Commission for Wales has proposed that the Dinas Powys electoral ward move from the Vale of Glamorgan constituency to join Cardiff South and Penarth.

An eight-week public consultation has opened to hear feedback on the plans, which would see the total number of Welsh MPs reduced from 40 to 32.

The proposed changes would also mean the electoral wards of Llanrumney and Rumney are removed from the Cardiff South and Penarth constituency into the existing Cardiff Central constituency.

The new borough constituency of Cardiff South and Penarth would have a total of 70,246 electors, comprised of the following, with the number of registered voters in each constituency:

Butetown (7,834)

Grangetown (13,257)

Splott (9,081)

Trowbridge (11,076)

Llandough (1,578)

Penarth Cornerswell Ward (4,069)

Penarth Plymouth Ward (4,584)

Penarth St Augustine's Ward (5,318)

Penarth Stanwell Ward (3,365)

The village of Sully (3,696)

Dinas Powys (6,388)

The changes are part of the 2023 review of Parliamentary constituencies in Wales, to ensure the statutory range of electors is between 69,724 and 77,062.

Only one existing constituency, the Vale of Glamorgan, is within the statutory range with 76,508 voters in the December 2019 election.

The removal of Dinas Powys from the Vale of Glamorgan is the only proposed change for that constituency, leaving a total of 70,426 electors.

A spokesperson for the Boundary Commission for Wales said these proposals were "the beginning, not the end" of the review process.

"These are our initial views. We look forward, during our review process, to hearing from the people of Wales on how these proposals might be amended and revised," they said.

The initial public consultation begins today and will end on 3 November 2021.
