With the question of its form of government (monarchy or republic) postponed to the post-war period, the country was now called the Federal Democratic Yugoslavia. a series of agreements reached by the Chairman of the National Committee for the Liberation of Yugoslavia (NKOJ), J. Broz Tito, and the Prime Minister of the Yugoslav Royal Government in Exile, I. Ubai. A second agreement was reached in Belgrade on 1 November 1944, supplemented by two additional agreements signed in Belgrade on 7 December. The new agreement provided for the formation of a unified Yugoslav government to replace the NKOJ and the government in exile. It preserved the federal democratic structure created as part of the national liberation struggle, understanding that the final form of government would be determined by a constituent assembly that would be elected three months after the liberation of the entire country. Until the Assembly addressed this issue, the king was banned from returning to Yugoslavia. The royal prerogatives would be assumed by a board of directors, while legislative power would be entrusted to AVNOJ. Democratic rights and freedoms would be guaranteed, including free activities for all political parties and associations, with the exception of those who cooperated with the occupying forces.
