The Greens’ amateurish social-media operation has been transformed. In the place of clunky graphics and dour tweets come slick, viral videos – Polanski urging us to “make hope normal again” – or sassy celebrations of each new membership milestone. The party’s on-screen presence has evolved, too. Previous TV outings by Green politicians could be described as awfully nice but lacking in cut-through messages. Polanski, however, has embraced the Nigel Farage tactic of confrontation, whether it be championing a wealth tax, backing transgender rights without equivocation or accusing Reform UK of fascism.
