Prime Minister of the Arab Union

The President of the Council of Ministers of the Arab Union (Arabic: رئيس مجلس الوزراء raʾīs majlis al-wazarāʾ), known in English sources as the Prime Minister of the Arab Union, is the head of government of the Union of Arab Republics (UAR; informally the Arab Union). The head of state is the President.

The Prime Minister chairs the Council of Ministers, the chief executive organ at the federal level of government. The Prime Minister of the Arab Union is nominated by the Arab Congress and formally appointed by the President. An incumbent prime minister must maintain the confidence of Congress in order to remain in office, although rare, constitutionally defined circumstances allow an incumbent's dismissal via presidential decree; in either case, Congress is uniquely responsible for the nomination of a successor.

The Prime Minister is responsible for appointing a deputy prime minister, who is the second most senior member of the Council of Ministers, whose day-to-day affairs he is responsible for managing as a de facto chief of staff.

The official residence and workplace of the Prime Minister of the Arab Union is the historical Merbad Palace, specifically its West Pavilion which, unlike the rest of the palace and the square it encloses, is permanently off limits to the public.
