yeah he defied the met police and went ahead and organised a public protest without being approved by the police i believe they refused the protest on public order grounds and got magistrates permission, we dont actually have any freedom of assembly in this country thanks to margaret thatcher and here public order act 1986. trying to stop miners than r tone made it illegal under terrorism law to mass assemble near parliament square without permission. police can refuse or impose restrictions by applying to a magistrates within 24 hours and you have to go through court to challenge them.
