Article: Nasser appointed himself the additional roles of prime minister and supreme commander of the armed forces on 19 June 1967. Angry at the military court's perceived leniency with air force officers charged with negligence during the 1967 war, workers and students launched protests calling for major political reforms in late February 1968. Nasser responded to the demonstrations, the most significant public challenge to his rule since workers' protests in March 1954, by removing most military figures from his cabinet and appointing eight civilians in place of several high-ranking members of the Arab Socialist Union (ASU). By 3 March, Nasser directed Egypt's intelligence apparatus to focus on external rather than domestic espionage, and declared the "fall of the mukhabarat state".
