The Swedish climate activist Greta Thunberg and four other activists have been cleared of a public order offence over a protest outside an oil and gas conference in London last October. The case against them was dismissed by a London court judge who ruled that the police had imposed “unlawful” conditions during the environmental protest. Thunberg, known for her prominent activism, had pleaded not guilty to breaching a public order law and has been involved in other recent protests. The judge’s ruling was hailed as a victory for the right to protest by Greenpeace UK. Thunberg and her co-defendants were seen hugging after leaving court.
