In the 1970s and 1980s Britain imported uranium from RTZ’s Rossing mine in Namibia in contravention of UN resolutions that said the country’s natural resources should only be sold with the consent of the UN Council for Namibia. The uranium was imported under contracts signed in the late 1960s by the UK Atomic Energy Authority and Rio Tinto Zinc. Lord Carrington, featured in the poster, was a Director of RTZ and British Foreign Secretary,1979–1982.
