Banning marches - the next step in a loss of a right to protest.
Of course, what about static rallies.
People who studied history will remember when the Government cracked down on protest.
Riot Act - Wikipedia
"Our sovereign lord the King chargeth and commandeth all persons, being assembled, immediately to disperse themselves, and peaceably to depart to their habitations, or to their lawful business, upon the pains contained in the act made in the first year of King George, for preventing tumults and riotous assemblies. God save the King."
And of course, the Peterloo Massacre - I do wonder what our Home Secretary is aware of this aspect of our social history and what her thoughts are on it?
