The office of vice president of the Socialist Federal Republic of Yugoslavia existed from April 1963 to June 1967. It was established by the new Yugoslav Constitution adopted on 7 April 1963. The first to serve in the role was Aleksandar RankoviÃÂ who assumed office on 30 June 1963. Due to an affair involving wire-tapping of Yugoslav president and general secretary of the League of Communists Josip Broz Tito, RankoviÃÂ was forced to resign from the Central Committee and from the vice presidency on 1 July 1966. He was subsequently replaced by KoÃÂa PopoviÃÂ two weeks later who served out the remainder of RankoviÃÂ's four-year term. On 26 April 1967 new amendments to the 1963 constitution were approved which disestablished the vice presidency once RankoviÃÂ and PopoviÃÂ's combined four-year term was up. The office ceased to exist on 30 June 1967.
