Students at Durham University first asked the university authorities to sell shares in companies with South African subsidiaries in 1972. In 1974 they rejected the response of the University Council, which endorsed the British government’s code of conduct for companies investing in South Africa. This poster publicised a national demonstration against the university’s refusal to sell, held in February 1975. Over 1,000 students marched through Durham. Speakers included trade unionist John Hosey, whose son Sean was imprisoned in South Africa. Durham University’s Vice-Chancellor responded by circulating other universities suggesting they should ensure British influence in South Africa was exerted against apartheid. This was rejected by Durham students, who continued to campaign for disinvestment.
