The Green party- 2029’s opposition?

2025 has not been a good year for the European left. The SPD experienced one of the worst nights in their history when they were thrashed by the CDU/CSU and AfD in February’s German elections. In Portugal, the Partido Socialista were edged by populist Chega, as the Democratic Alliance stormed to victory, and despite the D66’s Dutch victory, the left-wing GL-PvdA sank far enough for their leader to resign before results were even finalised.

This run of poor form extends beyond election campaigns, as seen to a great extent by Labour’s first calendar year in No. 10. Pressure is mounting on the centre-left party. Figures that Starmer needs to be loyal are now allegedly plotting against him, and as the leader’s reshuffle and reboot fails to take off time and time again, the same fundamental flaws in this government remain.

Notwithstanding recent signs of life, Labour’s traditional Tory arch-enemies have failed to capitalise on their opponents’ shortcomings as they usually would, as Badenoch continues to focus on the long-term. Instead, the right-sided challenge comes from Farage and Reform, who have taken much of Labour’s 2024 support at impressive pace.

Swathes of people have sprinted over the left-right divide in search of a better Britain, and by the start of September, it wouldn’t have been crazy to label 2029’s result as inevitable- a Reform majority. As the Labour party’s polling results appear to be one-way traffic of decline, it looked as if the left would be sitting out of the next general election.

Zack Polanski would have liked to claim overwise, and by December, he has already proved himself correct. Until Autumn, the Green party’s 2025 had followed a similar pattern to one described earlier- dismal and bleak stagnancy. Predecessors Denyer and Ramsey had led a group that was timid in attacking a spluttering Labour machine that was there to be destroyed.

Despite an increasingly frustrated and dissatisfied Labour left-wing, the Greens continued to poll at around 10%, highlighting this lack of combativeness. When the in-power party voted against the Liberal Democrat’s Climate and Nature Bill, Denyer was presented with the perfect opportunity to be bold and abrasive- yet a response was absent from their social media, and the Green leader failed to make a fuss.

Polanski was quick to realise member’s concerns as he pitched himself as the new leader. He believes that the Greens have great potential, but there must be a more cohesive drive towards this vision. For Polanski, his party can be the left’s answer to Reform- in his own words, they will be “eco-populist”.

These ideas have clearly resonated with members, as he strode to victory with 81.4% of the vote on the 2^nd of September. Interest in Polanski’s ideology has stretched beyond traditional Green party followers since his election. After six weeks, they had jumped from 10% to 13% in the polls, and by the 10^th November, results of 16% took them past the Liberal Democrats.

This new “eco-populist” Polanski-led phenomenon is now Labour’s biggest challenger on the left, and December polls suggest that they’re only 3% away from Starmer’s party- it is now feasible that the Greens could soon be the preeminent force of their side of the spectrum. They’re even closer to the Tories, who stand on 18%, meaning that they could soon be the most popular opposition to the Reform party hated so much by Polanski.

Of course, the new Green leader has polar beliefs to Farage, yet there is also much he admires about the potential future prime minister. Like Reform, Polanski has sought to stray from the tried and tested, promising a bolder, more confrontational communication style. He would like to move away from a “stats and spreadsheets style” (perhaps why he lacked basic economic knowledge when interviewed by Rory Stewart). However, whilst he approves of Farage’s “story-telling” rhetorical style, he believes it can be harnessed to spread a vividly different message.

As well as dialling up attacks on the conventional, Polanski has made efforts to widen the Green’s policy platform, arguing that the public cannot focus on climate issues if they face economic challenges. Crucial advocations have been for higher taxes on billionaires, including wealth tax, as well as the renationalisation of water companies and more regulation on businesses.

He has called for radical action to fix “unfair” systems, and has been a long-standing supporter of Universal Income, also campaigning for decent warm homes for all. Polanski has previously been arrested for activism with environmental protest group Extinction Rebellion, and has called for the government to take action on “genocide” in Gaza.

Many forbode the death of the Green party as Corbyn and Sultana began to rally troops earlier this year, but Your party has quickly descended into mutiny. Even before their premature collapse, Polanski saw the new group as an opportunity for co-operation rather than a threat, and has spoken about a collaboration with the former Labour leader on policy- however, this has stopped short of the proposal of an electoral pact, which could have provided a severe headache for Starmer.

That being said, the prime minister will already feel ringing in his ears. The Green party are no longer timid, well-meaning eco-warriors, but a fierce, relevant political force. Polanski has promised to “take the fight” to Labour, and this battle will be fascinating. He has embraced controversy in an attempt to swipe headlines and win attention, leading to a remarkably quick rise in popularity.

Unlike before, they have put themselves forward as answers to a question asked by many left-wing voters at present. They feel left behind by Starmer’s centre-wards movement and undeniable failure, but previously lacked options. Polanski believe that Labour are offering continuity of the 14-year Tory reign- and he may be incorrect, as in actual fact, Starmer’s first 18 months in power have been sensationally worse.

In an interview with Politico, Liz Truss stated that see thinks the Greens could end up being the official opposition in the next election. For once, she may be right- just as Reform have surged past the Conservatives on the right, Polanski could follow suit past Starmer on the left.

His style is exceptionally well-suited to the current climate- since his arrival, there has been a new sense of freshness, confidence and brashness surrounding the Green party. Unlike predecessors, he has centralised leadership and harnessed social media to greatly accelerate membership increases- they overtook the Tories last month to become the third largest party by members in the country.

The left has found its answer to the surge of the populist right-wing. It has discovered a ray of hope in a year of failure. Polanski has set a target of thirty seats by 2029- if the Greens can fill the void opened by Labour shortcomings, that target could be a something massively unlike him- unambitious. Few would have predicted it this Summer, but by Christmas, it looks feasible- the Green party could be opposition in 2029.
