Reform UK has announced its intention to report Green Party leader Zack Polanski to the police over an Instagram post that included an image of a guillotine alongside a man wearing a T-shirt with the slogan "We're only making plans for Nigel." The post was shared by Polanski to his 713,000 followers on Sunday.

Polanski shared a series of images from a Green Party event, accepting a request to collaborate with another account. One of the shared images featured the aforementioned T-shirt. Upon being made aware of the image, Polanski immediately removed it from his post. A spokesperson for the Green Party stated that Polanski "unequivocally does not support this type of dangerous message."

Nigel Farage, the leader of Reform UK, publicly criticized Polanski's post on X, formerly Twitter. Farage shared a screenshot of the reposted image and commented, "If I was to post anything as inciteful then I would expect to be arrested, and so should Polanski."

Reform UK's home affairs spokesperson, Zia Yusuf, described the content as "incitement to murder." The party is reportedly proceeding with reporting Polanski to the police.
