Reform UK has formally reported Green Party leader Zack Polanski to police after he shared a now-deleted social media post pairing guillotine imagery with references to Nigel Farage, including a T-shirt bearing the phrase "We're only making plans for Nigel". Reform's home affairs spokesperson branded the post incitement to murder, and the row has drawn in a cabinet minister who has publicly criticised Polanski, underlining cross-party unease about violent rhetoric directed at politicians.

The controversy comes amid heightened sensitivity following the murder of former Conservative MP Ann Widdecombe, which has sharpened scrutiny of inflammatory political messaging in Britain. The episode has reignited debate over the boundary between free expression and genuine threats to elected representatives' safety, with the police report against Polanski now central to that discussion.
