Don Valley (UK Parliament constituency)
Don Valley is a constituency in South Yorkshire represented in the House of Commons of the UK Parliament since 2019 by Nick Fletcher of the Conservative Party. Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat will be subject to boundary changes which will include gain of the Isle of Axholme in the Borough of North Lincolnshire and the loss of Conisbrough to the new constituency of Rawmarsh and Consisbrough. As a consequence, it will be renamed Doncaster East and the Isle of Axholme, to be first contested at the next general election. Constituency profile
Created in 1918, Don Valley is a former coal mining area which elected only Labour MPs from 1922 to 2019. The seat recorded a strong Brexit vote (69%) in the 2016 referendum. Boundaries
