The Swedish climate campaigner was arrested last month as she protested outside an oil and gas business event at a posh hotel in the capital.

She appeared at Westminster Magistrates’ Court on Wednesday accused of breaching the 1986 Public Order Act by failing to leave the road to protest on the pavement.

The 20-year-old arrived as Greenpeace and Fossil Free London campaigners protested outside the court, unveiling banners saying “Oily Money Out” and “Make Polluters Pay”.
