This poster reproduced an press advertisement calling on the 1989 Commonwealth Heads of Government meeting to impose further sanctions on South Africa. In 1986 the Commonwealth imposed limited sanctions, constrained by British Prime Minister Margaret Thatcher’s refusal to agree to more wide-ranging measures. The Southern Africa Coalition was a broad coalition of British organisations, including churches, trade unions, overseas development organisations and the AAM, launched on 1 September 1989 to pressure the British government ot impose targeted sanctions against South Africa.
