Anastas Mikoyan Quote
The principle of collective leadership is elementary for a proletarian party and for a party of the Lenin type. Nevertheless, we must emphasize this old truth, because for about 20 years we have had practically no collective leadership; there flourished the cult of the individual which was condemned first by Marx and then by Lenin. And this, of course, could not but reflect negatively on the position of the party and its work.
As quoted in "The World Almanac and Book of Facts" (1969), p. 159
