Thousands of protestors march in Edinburgh, Scotland, against the upcoming departure of the United Kingdom from the European Union. The crowd is addressed by Members of the UK Parliament, and Members of the Scottish Parliament. Amongst the attendees is MSP Joanna Cherry QC, who is taking legal action against UK Prime Minister Boris Johnson's recent prorogation of the UK Parliament. Cherry's action succeeded at Scotland's Court of Session, and is currently being reviewed by the UK Supreme Court.
