Under Mikhail Gorbachev, Politburo reports expanded to provide more details on the leadership's thinking about domestic and foreign affairs. Before Gorbachev's assumption of power, Western sources had identified a partial list of proscribed topics, which included crime, drugs, accidents, natural disasters, occupational injuries, official organs of censorship, security, intelligence, schedules of travel for the political leadership, arms sales abroad, crime or morale problems in the armed forces, hostile actions against Soviet citizens abroad, and special payments and education for athletes. After 1985 Gorbachev's policy of openness gave editors a freer hand to publish information on many of these subjects.
