Story summary

Zack Polanski, leader of the Green Party of England and Wales, has stated that his leadership does not hinge on winning the upcoming Holborn and St Pancras by-election. The race is described as a 50/50 contest between the Greens and Labour, with both sides recognizing its significance. Despite this, Polanski asserts that his position remains secure regardless of the outcome. However, senior party figures privately worry that a loss could undermine Polanski’s authority, given that the Green Party's surge in membership and polling has not yet translated into effective grassroots campaigning. Internal friction has arisen as resources are redirected towards the by-election effort to capture Keir Starmer's former seat from Labour.

Narrative

Referring to arrests of Palestine Action supporters outside the Labour party conference, Polanski said: “Those people on the doorstep, they can see that Ed Miliband stood on stage and told many of us that we were right on Palestine, but just behind him, outside the conference hall, pensioners were still being dragged off, being arrested for holding signs up saying ‘I support Palestine Action’.”

Claims (37 extracted, 6 hedged)

It’s really, really on a knife edge.” asserted
It → ’ → edge
Senior Green party figures privately fear defeat in Holborn and St Pancras could severely damage Polanski’s leadership, amid concerns the party’s rapid rise in membership and polling hasn’t translated into strong campaigning strength on the ground. uncertain
rise → fear → ground
Attempts to concentrate resources on the byelection have caused internal friction, with the Guardian revealing last month that Polanski wanted the Greens’ annual conference postponed so the party could focus on the contest. uncertain
party → concentrate → contest
That proposal was rejected by its executive. asserted
proposal → reject → executive
Polanski, who has never been an MP, maintained there were “still advantages to being a leader outside Westminster”, while also arguing that entering parliament would offer another way of putting pressure on the Labour government. asserted
entering → maintain → government
The byelection has become an early test of whether Labour under Andy Burnham can reclaim progressive voters who have moved towards the Greens, and the result may inform the government’s decisions over expanding North Sea oil and gas drilling. uncertain
result → become → drilling
“I see this election as high stakes for people in Holborn and St Pancras and high stakes for the climate crisis,” Polanski said. asserted
Polanski → see → crisis
“We know that … a decision on [drilling projects Rosebank and Jackdaw] has been delayed until after this by-election, because Andy Burnham literally wants to see whether he can get away with drilling for new North Sea oil and gas. asserted
he → know → oil
The Guardian has reported the Jackdaw decision was likely to be held until after the byelection, while a decision on Rosebank is still pending. asserted
decision → report → Rosebank
Burnham has promised a more “pragmatic” approach to North Sea oil and gas than his predecessor, as the government balances its climate commitments against pressure over energy security and jobs. asserted
government → promise → security
Both projects already hold licences granted under the Conservatives, meaning approval by Labour would not amount to issuing new exploration licences. asserted
approval → hold → licences
Asked whether Burnham’s surge could win back younger and progressive voters from the Greens, Polanski said there were two possibilities. uncertain
Polanski → ask → Greens
One was that Burnham “means what he’s saying right now” and would actually “implement action today and not tomorrow, and not after the next general election”. asserted
he → mean → election
In this case, Polanski said, the country would improve as a result of pressure from the Greens and others. asserted
country → say → Greens
The other, which Polanski called “the more likely scenario”, was that “what we’re getting is talk”. asserted
getting → call → what
He said Burnham was “promising things after the next general election, but soon we’re going to have a budget that he’s already warning is going to be a difficult budget”. asserted
he → say → budget
In this case, he said, “more and more people will start to question why would you vote for the Labour party or get involved with the Labour party when the Green party has been growing for over a year now”. asserted
party → say → year
He added: “You don’t have to accept the half-fat version. asserted
You → add → version
You can join the Green party and actually make sure we have the country that Andy Burnham’s talking about, but not taking the action on.” asserted
Burnham → join → action
Arguing that Labour’s climate policy has a gap between rhetoric and actions, Polanski asked: “Does Andy Burnham just not care about the climate crisis? asserted
Burnham → argue → crisis
It just feels like such a glaring gap in everything that he’s talked about, not just because of Rosebank and Jackdaw, but in the need to invest in renewables, the need for a clean green revolution, the need for new jobs, and it just feels like this vision is just not there.” asserted
vision → feel → jobs
He continued: “When are we going to see difficult choices for the super rich and the very, very wealthy? asserted
we → continue → rich
Instead, he’s talking about difficult choices for pensioners. asserted
he → talk → pensioners
So already, the action is not meeting his ‘hope’ rhetoric, and I think people are already starting to ask questions.” asserted
people → meet → questions
Referring to arrests of Palestine Action supporters outside the Labour party conference, Polanski said: “Those people on the doorstep, they can see that Ed Miliband stood on stage and told many of us that we were right on Palestine, but just behind him, outside the conference hall, pensioners were still being dragged off, being arrested for holding signs up saying ‘I support Palestine Action’.” asserted
I → refer → Action
Polanski is facing a separate test of his leadership at the Green party’s annual conference, where members are due to debate a deeply contentious motion declaring “Zionism is racism”. asserted
Zionism → face → motion
Asked about criticism from senior Greens who believe he has failed to provide leadership over the issue, he said: “Leadership is about priorities, and this motion isn’t my priority. asserted
motion → ask → priorities
My priority is nationalising Thames Water. asserted
priority → nationalise → Water
My priority is ending the genocide that’s happening in Gaza and freeing Palestine.” asserted
that → end → Palestine
Some Jewish Greens have raised concerns about what the motion could mean for their place within the party. uncertain
motion → raise → party
Asked whether he could guarantee that a Jewish member would not face disciplinary action simply for attending a synagogue that identified as Zionist, Polanski said: “I can guarantee that this motion has absolutely nothing to do with disciplinary action against anyone.” uncertain
motion → ask → anyone
