Now officially an independent nation, Indonesia adopted the Provisional Constitution, a document which defined the president's role as a ceremonial head of state whose role was to appoint a prime minister on the advice of formateurs. Although the vice presidency continued to exist, the form of government was now officially a parliamentary democracy and there was not a significant role for the vice president to play. On 1 December 1956, partly because of his differences with Sukarno, Hatta resigned from the Vice Presidency.
