Between the late 1940s and 1960s, the British government conducted secret chemical and biological weapons tests on its own population. Under the authority of the Ministry of Defence, experiments were coordinated from Porton Down and extended beyond military facilities into public spaces.
Service members and civilians were exposed without full knowledge or informed consent. One participant died during a nerve-agent test in 1953. The records were sealed. Accountability never followed.
