Solomon Mahlangu was sentenced to death on 2 March 1978 after being present at an incident in Johannesburg during which two white bystanders were killed. The AAM organised weekly demonstrations outside South Africa House calling for his release. Thousands signed a petition asking the British government to intervene. This picket was held on 2 August 1978.
