This petition was one of the first initiatives of Southern Africa the Imprisoned Society (SATIS), set up by the AAM, International Defence and Aid Fund (IDAF), National Union of Students, and Ruskin College and AUEW (TASS) Kitson Committees in December 1973. SATIS also asked supporters to adopt individual prisoners and organised a series of vigils on the steps of St Martin’s-in-the-Fields. The petition was signed by over 30,000 people and presented to the Chair of the UN Special Committee Against Apartheid at the AAM’s Freedom Convention on 30 June 1974.
