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.

A Green Party spokesperson said it was “obvious from the start” that no crime had been committed, and said Reform UK was “using this as a political football for their own cynical purposes” as a distraction.
