More than 10 million people are expected to take to the streets in 600 cities today as part of global demonstrations against a war in Iraq. It is anticipated that today's marches will be the largest ever for a single cause and far greater than at the height of the Vietnam war in the 60s. Last night London was celebrating peace, as politicians, poets, musicians, trade unionists and actors came together to lead debates and concerts. But protest organisers raised the stakes by calling on people to stage thousands of impromptu demonstrations, sit-ins, walkouts, strikes, vigils and acts of civil disobedience as soon as hostilities started." "We want people to strike on the day that war breaks out and occupy the whole Whitehall area of central London," said Lindsey German of the Stop the War Coalition.
