Green Party leader Zack Polanski is again battling controversy over his social media activity, raising fresh questions about whether the party has adapted to the scrutiny that comes with its growing political influence. Critics say the latest row risks overshadowing the Greens' electoral gains and exposing weaknesses in their leadership as they seek to establish themselves as a mainstream force.

Fresh Row Reignites Familiar Questions

The latest controversy erupted after Polanski shared an Instagram image showing a T-shirt featuring a guillotine alongside the words "We're Only Making Plans for Nigel". Reform UK accused him of "inciting murder", while Nigel Farage called for his arrest, although the Metropolitan Police later confirmed it would not investigate.

Appearing on Newsnight, Polanski described the post as an "inadvertent mistake" but stopped short of issuing an apology. The episode follows an earlier incident in April when he apologised for sharing criticism of the Metropolitan Police in the aftermath of the Golders Green terror attack, saying he had posted "in haste".

Success Brings a New Level of Scrutiny

Speaking on the In The Room podcast, former senior civil servant Helen MacNamara argued the Greens have yet to adjust to the demands of being a major political player.

She said the party's rapid rise, record membership and stronger polling inevitably bring tougher scrutiny, adding that behaviours which once attracted little attention now carry far greater political consequences.

Critics Say the Response Made Matters Worse

Political commentator Cleo Watson argued Polanski's television appearance deepened the controversy rather than ending it. She questioned why the Green leader acknowledged making a mistake but declined to apologise, saying a straightforward apology would likely have closed down the story.

Watson also expressed scepticism about the explanation that the slogan referenced XTC's 1979 song Making Plans for Nigel, arguing that senior politicians should ensure social media posts are carefully checked before publication.

A Party at a Crossroads

MacNamara suggested the repeated controversies reflect broader tensions within the Green Party. She contrasted its traditional image of community-focused environmental campaigners with a newer generation embracing a more confrontational, online political style.

Watson also questioned whether that strategy is delivering results, pointing to polling she said showed declining support among younger voters. For a party seeking to convert momentum into lasting electoral success, every online misstep risks becoming a wider test of credibility.

Why Zack Polanski keeps making the same mistake

Looks like both the Greens and Reform are on the decline. Maybe Burnham will call an election after all!
