Citizens for Sanctuary is a Citizen Organising Foundation campaign, made up of the country's largest alliance of civil institutions, calling for fair treatment and recognition for migrants in the UK. On May 4th 2009, 20,000 people marched to Trafalgar Square to show the UK government the broad coalition that supports an earned amnesty for irregular migrants. Members of the public were asked the question “Where do you find sanctuary?” and photographed together with their answers.
