The Green Party leader has said he made an "inadvertent mistake" when he shared the image with his social media followers.

The Metropolitan Police has said it will take no further action against Green Party leader Zack Polanski after he re-posted a photo of a man wearing a T-shirt with an image of a guillotine and the slogan "we're only making plans for Nigel". In a statement, the force said it did not believe sharing the picture constituted an offence. Polanski previously told the BBC he had made an "inadvertent mistake" by re-posting the image. In response to the Met's decision, a Reform UK spokesman said: "Once again we see that we are living in two-tier Britain." "Zack Polanski is allowed to get away with inciting murder whilst ordinary people up and down the country get a knock at the door for making a joke online." The Met said after careful review it had concluded it was unlikely the sharing of the image online would constitute a criminal offence. It said the post has been shared by about 130 accounts and the police should not treat individuals differently based on their public profile, meaning any investigation would have to consider all those accounts too. "Given it is unlikely their actions would have ultimately constituted an offence, such an extensive investigation was deemed to do be disproportionate and not a reasonable use of police resources."
