Monmouthshire (UK Parliament constituency)

The historic Monmouthshire constituency covered the county of Monmouth, except that from 1832 there was a borough constituency, Monmouth Boroughs, within the county.

The constituency was re-established as part of the 2023 review for the 2024 general election under the June 2023 final proposals of the Boundary Commission for Wales.{{Cite book |url=https://bcomm-wales.gov.uk/sites/bcomm/files/review/E02859434_Boundary%20Commission%20Wales%202023_English_Web%20Accessible_V03.pdf |title=2023 Review of Parliamentary Constituencies – The 2023 Review of Parliamentary Constituencies in Wales |date=28 June 2023 |publisher=Boundary Commission for Wales}} The boundaries were defined as being coterminous with the unitary authority of the County of Monmouthshire.{{Cite web |title=The Parliamentary Constituencies Order 2023 |url=https://www.legislation.gov.uk/uksi/2023/1230/made |at=Schedule 4 (Wales)}}

It was created from the abolished constituency of Monmouth (excluding the small part in Torfaen County Borough) expanded to include those parts of Monmouthshire County previously in the Newport East constituency, including Caldicot and Magor.
