A key member of the Kremlin’s inner circle has left his post as a foreign policy adviser to Soviet leader Mikhail S. Gorbachev. Andrei M. Alexandrov-Agentov, 67, retired and was replaced by Anatoly S. Chernyayev, 64, according to an aide to Sen. Edward M. Kennedy (D-Mass.), who visited Moscow last week. Alexandrov-Agentov assumed his post, roughly comparable to that of a White House national security adviser, under the late Leonid I. Brezhnev. He was kept on in the two short-lived regimes of Brezhnev’s successors, Yuri V. Andropov and Konstantin U. Chernenko, as well as by Gorbachev.
