Story summary

Zack Polanski, leader of the Green Party in London, is facing intense pressure after a recent Holborn by-election loss and a controversial vote regarding Zionism. The party's most respected figure, Caroline Lucas, criticized Polanski for his absence during an important vote, stating it was "a mistake not to show leadership" and called the motion "dangerous" and "divisive." This incident comes after earlier success in May local elections, but now highlights a rift between party members and MPs who are more engaged with daily politics. Polanski's leadership style has shifted from brash and outspoken to less popular among his base, potentially jeopardizing his position at the helm of the Green Party.

🔮 The result shows that the Green Party is now a political force in London, especially after its success at the May local elections.
🔮 The former bus driver allegedly entered a Sainsburys Local in Willesden three times between 6pm and 8.45pm from which he is barred under a criminal behaviour order ban.
🔮 In his letter, DCS Williams said: “The Met has repeatedly raised concerns that placing more criminals within the community comes with significant risks to victims and places more costs onto policing. “
🔮 Ministers have also admitted that the taxpayer could be left footing a bill for the controversial plan to expand the west London airport and are seeking guidance on “the Government exposure to programme costs and risks”.
🔮 But events at the Green Party’s conference, where members voted over the weekend to define Zionism as racism leading to Mr Polanski being barred from entering Israel, could have damaged his electoral prospects in north London.
🔮 Voters will go to the polls today as candidates fight to replace Sir Keir Starmer as the MP for Holborn and St Pancras.
🔮 Labour’s candidate Sagal Abdi-Wali is 1-33 favourite, followed by Green Party leader Zack Polanski on 12-1, then George Galloway, between 100-1 and 200-1 but who could still influence the election’s outcome.
🔮 In her keynote speech to the Tory annual conference in Birmingham, Mrs Badenoch was due to say that her party will fight a “battle for the soul of the nation” at the next election centred on tax-cutting promises.
🔮 “But if I win, that will keep Labour in check and make sure they act on the things that matter to Holborn and St Pancras: affordable housing, safe communities, and securing a safe future for our children.”
🔮 Mr Griffith used his conference speech to make clear that a future Conservative government would back the runway and take action to overcome obstacles.

Narrative

Many party members are more radical than MPs who are generally far more engaged in the day-to-day reality of politics and a number of senior Green figures voted against the motion but Mr Polanski was nowhere to be seen. “It was a mistake not to show leadership on this, and it was a mistake not to be there to vote,” says one of the Green’s most respected figures, Caroline Lucas, its first MP who represented Brighton Pavilion for 14 years.

But Mr Polanski’s popularity has been falling, according to at least one poll, since he was slammed by Met Police chief Sir Mark Rowley in the spring in a row over the arrest made following the double stabbing in Golders Green. uncertain

Mr Polanski, who contested the by-election in the face of the “Burnham bounce” for Labour in the polls, has vowed to carry on as Green Party leader and denied he had lost control of his party over the Zionism vote. “I’ve got a party that was 55,000, 60,000 members when I was running for leader, it’s now 220,000,” he said. asserted
