UK Green leader Polanski faces internal pressure after byelection defeat and poll slump

Zack Polanski, leader of the UK Green Party, is under mounting pressure following a byelection defeat in Holborn and St Pancras, a damaging internal row over Zionism, and polls showing his popularity below Nigel Farage's. The party's earlier victory in Gorton and Denton had raised expectations of replacing Labour, but the recent setback has triggered questions about his leadership. The outcome is uncertain, with no formal challenge announced yet, but the episode signals internal instability within a party that had been gaining momentum.
