 Sukarno left the country on a tour on 23 April, with the government confident of a two-thirds majority on the Assembly - sufficient to reintroduce the 1945 Constitution.However, the debate in the Assembly turned away from constitutional issues into the question of Islam, splitting the membership.The government tried to pressure the NU, but on 23 May, the proposal to include the Jakarta Charter was defeated in a plenary session of the Assembly and the NU turned against a return to the 1945 Constitution.
