Labour's Slipping Grip on Membership May Be Green Party's Gain The UK's Labour party has suffered a significant blow to its membership numbers, with a 20% drop in 2025 according to its latest accounts.
This decline comes as the Green party continues to surge forward, claiming that its membership has "quadrupled" under the leadership of Zack Polanski.
Labour's losses are particularly notable given the party's long standing reputation as a stalwart of progressive politics in the UK.
