The current Monmouthshire constituency of the House of Commons in the UK Parliament, was first contested at the 2024 general election, following the 2023 review of Westminster constituencies.
It previously existed as a county constituency of the House of Commons of the Parliament of England from 1536 until 1707, of the Parliament of Great Britain from 1707 to 1801, and of the Parliament of the United Kingdom from 1801 to 1885. It elected two Members of Parliament (MPs).
In 1885 the Monmouthshire constituency was divided to create North Monmouthshire, South Monmouthshire and West Monmouthshire.
Boundaries
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.[2] The boundaries were defined as being coterminous with the unitary authority of the County of Monmouthshire.
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.
