Musicians Little Steven and Jerry Dammers sign the SATIS petition calling for the release of detainees in South Africa. Altogether 30,000 South Africans were held in detention under the national State of Emergency imposed in June 1986. The petition was supported by the British Council of Churches and the TUC and was signed by a third of a million people in Britain. It was presented to the South African authorities, Prime Minister Margaret Thatcher and the UN Secretary-General on Human Rights Day, 10 December 1987.
