Quick Summary

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.

Story summary

The Holborn and St Pancras by-election in north London aims to replace former Prime Minister Keir Starmer as MP, with Labour's Dani Arbid facing Green Party leader Zack Polanski. The contest is seen as a test of Andy Burnham’s ability to restore faith in the Labour Party after its decline among left-wing voters over the Gaza war. While Polanski claims the race is close and urges voters for climate action and public ownership, recent controversies, like his party's "Zionism is racism" motion at their Brighton conference, have put pressure on him. Prime Minister Burnham has issued a last-minute appeal to back Labour candidate Dani Arbid, highlighting that the constituency has been a Labour stronghold since 1983. The election, held on October 7, could define Polanski’s leadership of the Green Party following its surge in membership and local election successes gaining over 440 councillors and control of five councils.

🔮 'We think it is wrong to have a Foreign Secretary who chooses to virtue signal over intelligence sharing in a way that will keep Britain safe, because that isn't serving the British people.
🔮 Attacking 'ghettoes' he told the Centre for Policy Studies event in Birmingham: 'There are parts of that town unfortunately - and the police will tell you this, it can be a very dangerous place - there are parts where white people won't go.
🔮 The Tories say it is needed because Labour – which has still not set out how it will reach its target of spending 3 per cent of GDP on defence by 2030 – is failing to do enough to guarantee the security of the UK, its overseas territories and bases in an increasingly hostile world.
🔮 Shadow Chancellor Andrew Griffith branded the looming charge – which will cost up to £7,500 a year for owners of properties valued at more than £2million – 'vindictive'. In his keynote speech to the Conservative conference in Birmingham, Mr Griffith warned the tax – due to take effect in April 2028 – would be 'simply unaffordable' for retired people in houses bought decades ago that have since soared in value, and that it would also hit commuters living in 'ordinary homes'.
🔮 Chief rabbi Sir Ephraim Mirvis became the latest critic today, saying the motion was a 'threat to British Jews and to Britain'. Mr Polanski - who was last night barred from entering Israel - desperately tried to row back by joining criticism of the motion levelled by the party's five MPs, but is facing growing anger at his lack of leadership. He faced accusations of political cowardice after astonishingly choosing to skip the vote in Brighton and instead campaign in Holborn and St Pancras ahead of the by-election he is standing in next week. He is expected to lose to Labour's Sagal Abdi-Wali in Holborn but allies today tried to set him a low bar for 'victory' in the contest.
🔮 In a move set to send shockwaves through the divided hard Left party's ranks, members backed a conference proposal that calls for Israel to be treated like apartheid South Africa by 1,022 votes to 813.
