Arab Congress

The Arab Congress (Arabic: المؤتمر العربي al-mu’tamr al-‘arabī) is the bicameral legislature of the Union of Arab Republics, the legislative branch of the federal government, consisting of two nominally equal chambers: the Council of Deputies and the Council of Republics. The two chambers of the Arab Congress together elect the Prime Minister of the Arab Union, who leads the Council of Ministers, the executive branch of the federal government.

Council of Deputies
The Council of Deputies functions as a traditional "lower chamber", in that its 545 seats each represent a single electoral district, each being roughly equal in population, whose constituents elect a single representative, their Deputy (نواب nawāb). Deputies act as the direct representative of their electoral district in the federal government, and can be removed from office by their constituents.

Council of Republics
The Council of Republics is the "upper chamber" of the Arab Congress, and is often colloquially referred to as the Senate (مجلس الشيوخ majlis ash-shuyūkh, lit. “Council of Elders"). The 100 elected members of the Council of Republics are referred to in English as Senators, literally "Elders" in Arabic (شيوخ shuyūkh; sing. شيخ shaykh). Each member republic is represented by 5 Senators, who are directly elected by the voters of their republic. As each voter may nominate up to 5 individual candidates for their republic, it is common to see Senators of the same republic from more than one political party.
