Bassetlaw /ˈbæsɪtˌlɔː/ is a parliamentary constituency[n 1] in Nottinghamshire, represented in the House of Commons of the UK Parliament since the 2024 general election by Jo White, a Labour Party candidate.

The Bassetlaw constituency is mostly rural and covers the north of Nottinghamshire, including the towns of Worksop and Retford.

[3] 2010-2024: Following its review of parliamentary boundaries in Nottinghamshire, the Boundary Commission for England made changes to the constituency for the 2010 general election to allow for population changes, most noticeably by returning the town of Retford from Newark, offset by moving the small town of Market Warsop into Mansfield constituency.

In that year, the town of East Retford and the neighbouring areas were transferred to the redrawn Newark constituency.

On a historical measure, this had been a very safe seat for the Labour Party before 2019, with their own or related candidates having held it since the 1929 general election.

In 2019, Mann resigned being having been appointed to head a government inquiry on tackling anti-Semitism and to take a seat in the House of Lords.

[7] The Labour candidate initially chosen to replace Mann, Sally Gimson, was deselected before the election by the party's National Executive Committee over what were described as "very serious allegations".

[12] In the 2024 General Election, Jo White, the wife of John Mann, regained the seat for Labour on a swing of 19.6%.
