 The Congress soon joined the new Indian ministry . The League was slower to do so , not entering until October 1946 . In agreeing to have the League join the government , Jinnah abandoned his demands for parity with the Congress and a veto on matters concerning Muslims . The new ministry met amid a backdrop of rioting , especially in Calcutta . The Congress wanted the Viceroy to immediately summon the constituent assembly and begin the work of writing a constitution and felt that the League ministers should either join in the request or resign from the government . Wavell attempted to save the situation by flying leaders such as Jinnah , Liaquat , and Jawaharlal Nehru to London in December 1946 . At the end of the talks , participants issued a statement that the constitution would not be forced on any unwilling parts of India . On the way back from London , Jinnah and Liaquat stopped in Cairo for several days of pan @-@ Islamic meetings .
