On 1 July 1988, the fourth and last day of the 19th Party Conference, Gorbachev won the backing of the delegates for his last minute proposal to create a new supreme legislative body called the Congress of People's Deputies of the Soviet Union. Frustrated by the old guard's resistance to his attempts to liberalise, Gorbachev changed tack and embarked upon a set of constitutional changes to try and separate party and state, and thereby isolate his conservative opponents. Detailed proposals for the new Congress of People's Deputies of the Soviet Union were published for public consultation on 2 October 1988, and to enable the creation of the new legislature the Supreme Soviet, during its 29 November to 1 December 1988 session, implemented the amendments to the 1977 Soviet Constitution, enacted a law on electoral reform, and set the date of the election for 26 March 1989.
