Gorbachev's leadership style differed from that of his predecessors. He would stop to talk to civilians on the street, forbade the display of his portrait at the 1985 Red Square holiday celebrations, and encouraged frank and open discussions at Politburo meetings. To the West, Gorbachev was seen as a more moderate and less threatening Soviet leader; some Western commentators however believed this an act to lull Western governments into a false sense of security. His wife was his closest adviser, and took on the unofficial role of a "first lady" by appearing with him on foreign trips; her public visibility was a breach of standard practice and generated resentment. His other close aides were Georgy Shakhnazarov and Anatoly Chernyaev.
