Stop the War Coalition The coalition intends to send a wave of disruption across the country. Initial protests will come as early as noon on the first day of fighting, when there will be mass walkouts from schools and workplaces. These will be followed by demonstrations in city centres at 6pm. In London, the coalition hopes to bring Whitehall to a standstill as protesters march from Trafalgar Square to Westminster. On the first Saturday of the war, there will be a national demonstration in London, followed by a rally at Hyde Park. Andrew Murray, the coalition's chairman, expects local groups to instigate their own non-violent direct action campaigns.
