Andorra is a constitutional monarchy in which an elected government manages day-to-day national policy while the monarch serves as head of state. Xavier Espot Zamora serves as Prime Minister of Andorra and leads the government within the country's parliamentary and constitutional framework.
Andorra is a parliamentary co-principality. Two co-princes—the president of France and the bishop of Urgell—serve jointly as heads of state, while day-to-day executive authority is exercised by a head of government and cabinet responsible to the elected legislature. The modern constitution limits the co-princes to defined constitutional functions and places ordinary political government in elected institutions.
Legislative authority is exercised through a unicameral national parliament or assembly. It passes legislation, approves the budget, and performs the oversight and appointment functions assigned to it by the constitution. The judiciary is formally separate from the political branches, with the highest courts responsible for interpreting law and, where the constitutional system provides for it, reviewing constitutional questions.
Andorra is a unitary state, meaning sovereign authority is principally vested in national institutions, although local and regional governments exercise powers assigned by law. The constitution defines the relationship among the executive, legislature, judiciary, and subnational administration. Political authority is exercised through the constitutional institutions described above, with elections, parliamentary confidence, or other constitutional procedures determining who holds office.
