1931 - . Soviet `reform' communist politician, president of the Russian Republic from 1990. He was Moscow party chief 1985-87, when he was dismissed after criticizing the slow pace of political and economic reform. He was re-elected in Mar 1989 with a 89% share of the vote, defeating an `official Communist Party' candidate, and was elected to the Supreme Soviet in May 1989. He supported the Baltic states in their calls for greater independence and has demanded increasingly more radical economic reform. In Apr 1991 the Russian Republic congress voted him emergency powers. Yeltsin began his career in the construction industry. He joined the Communist Party of the Soviet Union (CPSU) in 1961 and became district party leader in Sverdlovsk 1976. Brought to Moscow by Mikhail Gorbachev and Nikolai Ryzhkov in 1985, he was appointed secretary for construction and then, in Dec 1985, Moscow party chief. A blunt-talking, hands-on reformer, Yeltsin was demoted to the post of first deputy chair of the State Construction Committee in Nov 1987. This was seen as a blow to Gorbachev's perestroika initiative and a victory for the conservatives grouped around Yegor Ligachev. In 1990 he renounced his CPSU membership and was elected president of the Russian Republic, the largest republic of the USSR. Having criticized the slow pace of economic reform effected by the Gorbachev-Ryzhkov team and advocated greater autonomy (economic and political sovereignty) for the constituent republics within a federal USSR, Yeltsin prompted the Russian parliament in June 1990 to pass a decree giving the republic's laws precedence over those passed by the Soviet parliament.
