[n 2] Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat was subjected to moderate boundary changes and reformed as Normanton and Hemsworth, to be first contested at the 2024 general election.

Nearby to the east over the border in North Yorkshire is Kellingley Colliery, which closed on 18 December 2015, marking the end of deep-pit coal mining in Britain.

Successive boundary changes removed certain ex-mining communities to the new Barnsley East constituency in 1983: this and the addition of the more Conservative-inclined ward of Wakefield South in 1997 slightly reduced Labour's dominance, but Hemsworth remained a safe seat in the 2017 election.

However, in 2019 the majority was cut from over 10,000 to just 1,180 as Labour's vote collapsed in Northern former mining seats, making it marginal for future elections.

This constituency covered the towns of Hemsworth, Featherstone, South Kirkby & Moorthorpe and South Elmsall, plus the southern part of Wakefield (Sandal, Agbrigg, Belle Vue) and the villages of Ackworth, Crofton, Fitzwilliam, Upton, Sharlston, Streethouse, Walton and Notton in the City of Wakefield district.
