In the borough containing Kim Leadbeater’s Spen Valley constituency, Labour lost every single council seat it held in England's local election, only weeks after the historic collapse of the Labour MP’s assisted suicide Bill.
Across the elections on 7 May for Kirklees District Council, which entirely contains Kim Leadbeater’s Spen Valley parliamentary constituency, the Labour Party did not win a single seat. The Party went from being the largest party on the council before the election, with 23 seats, to now not having a single seat on the entire council.
Electoral Calculus, which predicts outcomes for elections, now predicts that Kim Leadbeater MP will lose her seat at the next general election, with Reform UK having a 46% chance of winning, at the time of writing.
The loss of all Labour seats within Kirklees District Council and the losses experienced by the Labour Party following the elections that took place on 7 May 2026, come only weeks after the failure of the assisted suicide Bill in the House of Lords.
