Multiple outlets report that the Labour Party’s membership declines sharply in 2025. LabourList and the Daily Express both state that the party loses more than 20% of its members over the year. The figures referenced by LabourList are described as being published by the Electoral Commission, indicating the change is based on official reporting. The Daily Express similarly frames the drop as occurring within a single year, emphasizing the scale of the reduction. Across the two accounts, there is agreement on the direction of change (downward), the rough magnitude (just over or more than a fifth), and the timeframe (during 2025 or within a year). Neither source, in the text provided, gives further detail such as the exact start and end membership numbers, regional breakdowns, or reasons for the decline. Overall, the reporting centers on the same headline result: Labour’s membership decreases by more than 20% in 2025, according to published figures.
