Greta Thunberg has walked free from court after the district judge threw out the public order charge against her.

District Judge John Law said that the police had attempted to impose "unlawful" conditions during an environmental protest.

The 21-year-old was arrested after staging a demonstration outside a London hotel, where oil executives were meeting on October 17.

Thunberg pleaded not guilty to breaching Section 14 of the Public Order Act 1986 alongside two Fossil Free London (FFL) protesters and two Greenpeace activists.
