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 colloquially as the Prime Minister (رئيس الوزراء raʾīs al-wazarāʾ), is the head of government of the Union of Arab Republics (UAR; informally the Arab Union). The office of head of state is vested in the President of the Arab Union.
The Prime Minister chairs the Council of Ministers, the chief executive organ (cabinet) at the federal level of government. The Prime Minister is nominated by the Arab Congress as a whole and formally appointed by the President of the Arab Union. According to the Constitution of the Arab Union, an incumbent prime minister must maintain the confidence of Congress in order to remain in office, and 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 and his deputy 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 guided public tours.
