The constituency retained its name and gained wards, as part of the2023 review of Westminster constituencies and under theJune 2023 final recommendations of theBoundary Commission for Wales for the2024 general election.^[2]

1983–2024: The Borough of Torfaen, excluding the communities ofCroesyceiliog andLlanyrafon which were part of theMonmouth constituency.

2024–present: Under the 2023 review, the constituency was defined as being composed of the whole of theCounty Borough of Torfaen, with Croesyceiliog and Llanyrafon being transferred from the now abolished constituency of Monmouth, which was replaced byMonmouthshire.^[3]

The constituency covers thenew town ofCwmbran,Pontypool, and its surrounding districts and stretches as far north asBlaenavon.

The area is traditionally a Labour Party stronghold with a majority of around 9,000. The community ofNew Inn is the only strong Conservative area. It voted Labour even amidst the huge Conservative majorities of1983 and1987. However,2019 saw the lowest Labour majority in Torfaen in the seat's history, of only 3,742 votes, in part due to 60.8% of voters choosing the Leave vote in the2016 EU membership referendum.^[4] In the2024 United Kingdom general election Labour increased their majority to 7,322 votes.
