Green Party leader Zack Polanski faced a significant setback when he lost a by-election in Holborn and St Pancras to Labour candidate Sagal Abdi-Wali by more than 3,000 votes. The defeat followed a controversial party conference vote that labeled Zionism as racism, leading some members, including former leaders, to call for Polanski's resignation due to what they see as his failure to address the motion adequately. Senior figures within the Green Party are now questioning Polanski’s leadership, with Caroline Lucas suggesting he should have been present and voted on the contentious issue.
