The Council of State (Norwegian: Statsrådet), is a formal body composed of the most senior government ministers chosen by the Prime Minister, and functions as the collective decision-making organ constituting the executive branch of the Kingdom. The council simultaneously plays the role of privy council as well as government Cabinet. With the exception of the Prime Minister and the Minister of Foreign Affairs, who retain their ministerial ranking in their own right, all the other members of the Cabinet concurrently hold the position of statsråd, meaning Councillor of State, and that of Chief of the various departments, not formally being considered 'ministers', although commonly addressed as such. The Cabinet normally convenes every week, usually on Fridays at 11:00 a.m. at the Royal Palace, Oslo, and is presided over by the Monarch. Constitutional basis Under the 1814 Constitution of Norway, the third-oldest national Constitution still in operation (after the constitution of San Marino and US Constitution), the King is the head of the executive branch of Norway. However, historical developments such as the introduction of parliamentarism in 1884 and evolving constitutional tradition have altered the King's role, meaning that the Prime Minister, holding the leadership of a political party enjoying electoral support, is the de facto head of government. Accordingly, when Article 3 of the Constitution reads, "The Executive Power is vested in the King", this nowadays reflects the powers conferred on the elected government, operating through the Council of State and headed by the Prime Minister. The parliamentary system of Norway entails that the Cabinet must not have Parliament against it, and that the appointment by the King is a formality. The members making up the Council of State require the confidence of the Norwegian legislative body, known as the Storting. In practice, the monarch will ask the leader of a parliamentary block that has a majority in the Storting to form a government. After elections resulting in no clear majority to any party or coalition, the leader of the party most likely to be able to form a government is appointed Prime Minister. The fact that the original wording of the Constitution has not been modified to reflect contemporary practice, is a testimony to the widespread conservative sentiments shared across the political aisle that extensive constitutional revision should be avoided. In practice, this means that the function, authority and mandate of the Council of State is heavily influenced by
