Four people, including two from the South, have been charged following a climate change protest outside Buckingham Palace that saw activists chain themselves to the gates.
Peter Coville, 45, from Reading, will appear in court next month alongside Fiona Brooke, 23, of Billingshurst Road in Horsham, Sussex; Cyril Zeldine, 33, of Pimlico, south west London, and Philip Thornhill, 57, of Woolwich, south east London, the Metropolitan Police said.
The four were arrested after demonstrators - who said they represented the Climate Siren group - scaled the Palace gates and secured themselves to the railings.
They were bailed to appear at London's Westminster Magistrates' Court on July 10.
