Polanski faces ongoing scrutiny over social media post

What's happened

Green Party leader Zack Polanski has refused to apologise for a social media post featuring a guillotine and the slogan "We’re only making plans for Nigel." Police are reviewing the incident after Reform UK reports. Polanski says it was an inadvertent mistake and he is cooperating with inquiries. The controversy has intensified debates over a leader’s control of social media and the party’s future credibility.

What's behind the headline?

Analysis

• Polanski’s personal social media use is under heightened scrutiny as he manages multiple accounts. This fuels questions about vetting and due diligence within the Green Party.
• The image has been widely shared by opponents to frame Polanski as irresponsible, which could undermine party credibility ahead of by-elections and future campaigns.
• The police review underscores the potential stakes of online posts in British politics, especially when linked to violence imagery.
• The story highlights tensions within the Green Party between traditional local campaigning and a new, highly online political approach.
• Look for how the party’s leadership communicates around social media policy and whether this becomes a broader call for stricter internal controls.

How we got here

Polanski shared a carousel of images from a Green Party event on Instagram, where one image showed a man wearing a T-shirt with the phrase and a guillotine. The post was later unshared. Reform UK has reported the incident to police. The Metropolitan Police say they are reviewing the matter; Avon and Somerset Police may assess if any action is needed. The episode follows prior criticisms of Polanski’s social media activity and a separate incident related to Golders Green.
