Some historians are convinced that by 1964 Mikoyan believed that Khrushchev had turned into a liability to the Party, and that he was involved in the October 1964 coup that brought Brezhnev and Alexei Kosygin to power. However, William Taubman disputes this, as Mikoyan was the only member of the Presidium (the name for the Politburo at this time) to defend Khrushchev. Mikoyan, however, did vote to force Khrushchev's retirement (so as, in traditional Soviet style, to make the vote unanimous). Alone among Khrushchev's colleagues, Mikoyan wished the former leader well in his retirement, and he, alone, visited Khrushchev at his dacha a few years later. Mikoyan laid a wreath and sent a letter of condolence at Khrushchev's funeral in 1971.
