Mas'ari, a professor of Physics in Saudi Arabia, was jailed in 1993 for dissidence but fled to Yemen and thereafter to Britain where he sought political asylum. While his application was under consideration, Mas'ari—through his organisation, the Committee for Defence of Legitimate Rights—campaigned against corruption and the denial of democratic rights in Saudi Arabia. As leaked correspondence between the British armaments industry and the government and other reports suggest, the Saudi rulers were incensed and started denying British firms armaments contracts.
