Prevention and Suppression of Terrorism

May I suggest to my right hon. Friend that his Department look into the possibility of confining marches to a static location? The fact is that all people are currently being inhibited from attending central London at weekends and that is having a significant impact on commerce and shopping in the west end. I would not want to see demonstrations inhibited by having costs imposed on them, but it seems a perfectly reasonable compromise after so many marches to have static locations.
