In early 1986, Yeltsin began sniping at Gorbachev in Politburo meetings. At the Twenty-Seventh Party Congress in February, Yeltsin called for more far-reaching reforms than Gorbachev was initiating and criticized the party leadership, although did not cite Gorbachev by name, claiming that a new cult of personality was forming. Gorbachev then opened the floor to responses, after which attendees publicly criticized Yeltsin for several hours. After this, Gorbachev also criticized Yeltsin, claiming that he only cared for himself and was "politically illiterate". Yeltsin then resigned as both Moscow boss and as a member of the Politburo. From this point, tensions between the two men developed into a mutual hatred.
