In 1964, opposition within the Politburo and the Central Committee led to Khrushchev's removal as First Secretary. Leonid Brezhnev succeeded Khrushchev to the post as part of another collective leadership, together with Premier Alexei Kosygin and others. The office was renamed General Secretary in 1966. The collective leadership was able to limit the powers of the General Secretary during the Brezhnev Era. Brezhnev's influence grew throughout the 1970s as he was able to retain support by avoiding any radical reforms. Yuri Andropov and Konstantin Chernenko ruled the country in the same way as Brezhnev had. Mikhail Gorbachev ruled the Soviet Union as General Secretary until 1990, when the Communist Party lost its monopoly of power over the political system. The office of President of the Soviet Union was established so that Gorbachev still retained his role as leader of the Soviet Union. Following the failed August coup of 1991, Gorbachev resigned as General Secretary. He was succeeded by his deputy, Vladimir Ivashko, who only served for five days as Acting General Secretary before Boris Yeltsin, the President of Russia, suspended all activity in the Communist Party. Following the party's ban, the Union of Communist Parties – Communist Party of the Soviet Union (UCP–CPSU) was established by Oleg Shenin in 1993. The UCP–CPSU works as a framework for reviving and restoring the CPSU. The organisation has members in all the former Soviet republics.
