Will Zack Polanski’s Parliament push help Greens recover in polls?
Green support plummets as new PM wins back Labour voters and leader smarts over gaffes
Zack Polanski will need to reverse his party’s faltering fortunes if he is to win the Holborn and St Pancras by-election created by Keir Starmer’s decision to leave Westminster.
Membership of the Greens has more than tripled since Polanski was elected leader almost exactly a year ago and they won their first Westminster by-election in Gorton and Denton in February. Now the leader has said he wants to stand in the vote to replace former PM Starmer in the London constituency and become his party’s sixth MP.
But the Greens have also been dogged by accusations of antisemitism, while Polanski has been criticised for a series of gaffes. There have been questions over his tax affairs, his “inflated CV and ever-presence on social media”, said Pieter Snepvangers in The Telegraph.

What did the commentators say?
Polanski’s likely candidacy “makes what was expected to be a Labour hold into a much more interesting race, with Green activists already flooding [the] constituency”, said The Guardian’s political editor Pippa Crerar on X.
With Andy Burnham riding a wave of optimism as the new prime minister, the Green Party’s popularity has “plunged to its lowest level ever recorded”, said Snepvangers. A YouGov poll carried out in July put its net approval rating at -23, down 28 points from last August. A majority of the public (56%) has a negative view, up from 39%.
Polanski is “easy to dislike”, said Eliot Wilson in City A.M.: there is something “preposterous and confected about him”. He demonstrates “armour-plated self-belief”, even when he’s declaring “the most implausible silliness”.
But many voters still “like what they’ve heard”. And party leaders compete now not to be the most popular, but to be the least unpopular – Polanski is far less unpopular than Kemi Badenoch and Nigel Farage. But “the party’s position has begun to slide” and its policy platform is “uncompromising yet unrealistic”. The question now is: “How is the Green Party to stop this leakage?”

To be fair, a fifth of the country still likes Polanski, said Ben Walker in The New Statesman. But “a lot more people now feel negatively towards him”, especially voters over 35. “This may not be down to any missteps on his part. Rather, the Greens may have just reached their natural ceiling.” But the prospect of winning power “looks far away”.
True, the “unexpected resurgence of hope” in the Labour Party poses “an unmistakable threat” to Polanski, who previously “had a virtual monopoly on such things”, said Gaby Hinsliff in The Guardian. Newcomers to the Green Party are now “squarely in Burnham’s sights” as he apologises for the way Starmer handled the Gaza war. But it would be “ridiculous” to assume “this Labour honeymoon can last”. With the Greens “unconstrained by the realities of government”, they will have “the freedom to say whatever Labour won’t”. That could “easily become a powerful weapon”.
At the 2024 general election, the Green candidate came third in Holborn and St Pancras, nearly doubling the party’s vote share in 2019. Meanwhile, Labour’s majority fell dramatically. Hence the “immediate pressure” on Polanski to stand, said John Rentoul in The Independent. I expect Labour will hold it, provided they choose a “solid candidate” – it is “by no means” a safe seat. But Burnham has “calmed the anti-politics rage a little, and I think Polanski will fail to catch the wave at the right moment”.
What next?
Polanski is now under pressure from Green activists to “take more radical left-wing stances to halt the rising popularity of Labour”, said Aubrey Allegretti in The Times. Animah Kosai, a member of the Green Party Council, has tabled a motion to be debated at the Greens’ conference in October. It urges the party to “embrace more enthusiastically the kind of radical policies which excite activists”, said Wilson in City A.M., including the pledge to introduce a wealth tax and attacking Labour for the sale of arms to Israel.
Holborn and St Pancras “has long been a Labour stronghold” and Labour “will throw everything at defending it”, said The Guardian’s Crerar. In the way Makerfield was Burnham’s proof of concept that he could beat Reform, “Holborn and St Pancras will be his test that he can win back progressive voters to the Labour fold”.
