Nato, climate and media attacks: 3 things driving Zack Polanski’s rise
Zack Polanski’s ascent has been fast enough to unsettle both supporters and critics, and Nato has become one of the symbols around which that new scrutiny is forming. In just seven months as Green Party leader in England and Wales, he has helped drive an explosion in support, pushed the party into contention for second place in voter support, and attracted fierce hostility in return. The result is a rare political moment: a fringe figure no longer being ignored, but watched closely enough that every line of attack now carries its own political weight.
From overlooked to overexposed
Until recently, Green leaders in England and Wales feared irrelevance. Polanski has inverted that problem. His party is now riding high in national opinion polls, and local elections on May 7 are expected to test whether that momentum can translate into seats and influence. In London, the Greens are threatening to swamp Labour in what has been described as its final bastion, while gains are also expected elsewhere in England and Wales. That rapid rise has made Polanski a target, but it has also made his party harder to dismiss.
The attention is not limited to policy detail. It is about status. Polanski, 43, has been cast as the latest It Boy of British politics, a label that signals visibility as much as substance. The same rise that has boosted his profile has also generated a surge in enmity, reflecting a political environment in Britain that is divided, restless and uneasy. For a party long accustomed to being sidelined, that level of hostility is evidence of success as much as exposure.
Why Nato is part of the argument
Polanski’s position on Nato sits within a wider set of claims that his critics describe as economic wishful thinking. The debate matters because it touches defence, jobs and the credibility of his broader approach. In Scotland, he is campaigning ahead of the Holyrood election while facing criticism that his head is in the clouds on defence jobs, clean energy and the oil industry. The charge is not simply that his ideas are unpopular; it is that they would have consequences far beyond party branding.
That tension is sharpened by the contrast between aspiration and scale. Critics argue that if spending on the armed forces were scaled back, civilian jobs linked to defence contracts on the Clyde and at Rosyth in Fife could be affected. At the same time, Polanski’s supporters see him as offering a sharper break with old assumptions. The dispute over Nato therefore becomes a proxy for a larger argument: whether the Greens are presenting a serious governing philosophy or a protest politics dressed as renewal. The keyword sits inside that debate because it forces voters to ask how far a new Green agenda can stretch before it collides with existing security and employment structures.
Climate politics and the cost of disruption
Climate remains the central promise of Polanski’s appeal, but it is also where the hardest questions land. His critics say that replacing fossil-fuel employment with wind and solar jobs is fantasy if done abruptly. They warn that Scotland needs a just transition from fossil fuels to clean renewable energy, not a short, sharp shock that would destroy jobs and send bills soaring. That argument frames Polanski’s climate politics not as denial of the issue, but as skepticism about speed, delivery and economic realism.
This is where his appeal and his vulnerability overlap. His style is energetic, direct and media-savvy, and he has built a brand around what he calls “ecopopulism”. Yet the same language that helps him cut through can also invite suspicion that hard trade-offs are being simplified. The rise in support suggests the message is resonating. The criticism suggests the price of that resonance may be growing, especially if expectations outrun what the party can actually deliver.
Media attacks and the politics of legitimacy
Polanski has not responded to hostility by retreating. He has embraced the confrontation. He says criticism is the biggest compliment he could imagine and insists he is not scared, adding that he has truth and communities on his side. That posture matters because it turns media attacks into political fuel. Instead of defending himself in the language of caution, he presents himself as a figure being challenged precisely because he is effective.
That strategy carries risk. His critics allege that his promises are built on populist wishful thinking and that his party has been infiltrated by cranks, including anti-Semites. The comparison with the Corbyn era is hard to miss, though the political colouring is different this time. What Polanski has achieved is to force a larger conversation about whether a radical-left Green project can be both insurgent and credible at the same time. In that sense, Nato is only one flashpoint among several, but it is a revealing one because it exposes the strain between message discipline and policy consequence.
What the wider impact could be
The broader significance reaches beyond one party leader. If the Greens continue to surge, they will shape debates over defence, climate and public spending well beyond their current base. Their gains among socially conservative British Muslims, including the February by-election win in Gorton & Denton with a strong surge in support from voters of Kashmiri and Bengali descent, suggest the party is also crossing social boundaries that once looked unlikely. That makes Polanski harder to pigeonhole and harder to ignore.
The next test is whether this growth can survive sustained scrutiny. The answer will matter not just for the Greens, but for every party trying to understand how quickly political identity can shift when outrage, aspiration and media attention collide. If Polanski keeps rising, can he turn controversy into lasting authority, or will the force that made him visible also define the limits of his project and its handling of Nato?
