Masyumi Party
Following the resignation of the Third Sjahrir Cabinet on 27 June 1947, President Sukarno called a meeting with the leaders of the Masyumi Party, the Indonesian National Party (PNI), the Socialist Party and the Labour Party to ask them to form a cabinet. However, the party leaders were unable to agree to Masyumi's demands for senior ministerial posts that would have enabled it to dominate the cabinet. Finally, on 3 July, agreement was reached between the PNI, the Socialist Party, the Labour Party and the Masjumi breakaway party, the Indonesian Islamic Union Party (PSII), to support Amir Sjarifuddin as prime minister.
