Labour Membership Falls 200,000 Since 2019 Peak

Labour has experienced a significant decline in membership, losing nearly 200,000 members since the end of Jeremy Corbyn’s leadership, with the party’s ranks falling from 532,046 in 2019 to 333,235 by the end of 2024. Despite a landslide general election victory in July 2024 under Sir Keir Starmer, the party still lost over 37,000 members that year, representing about 10% of its total membership. A poll indicated that around 28% of current Labour members might consider joining the new left-wing party launched by Jeremy Corbyn and Zarah Sultana, posing a further risk to Labour’s membership base. Labour remains the largest political party in the UK, though Reform UK has seen a surge in membership to approximately 234,000, while the Liberal Democrats and Greens have experienced minor membership changes. Financially, Labour reported a £3.8 million loss after spending £94.5 million in the past year, in contrast to surpluses recorded by smaller parties like the Liberal Democrats, Reform UK, and the Greens. The Conservative Party’s membership figures are not routinely published, but it showed increased income from membership fees despite a drop in eligible voters for its leadership election.
