Ministry of Foreign Affairs (Sierra)

The Ministry of Foreign Affairs is the Cabinet-level ministry in the Government of Sierra that manages and oversees the diplomatic and consular relations of Sierra. Its primary responsibility is to advise the Prime Minister on international affairs and foreign policy issues, who exercises the Queen's royal prerogative on Her Royal Majesty's behalf. It is also responsible for negotiating treaties and agreements with other powers, representing Sierra in international organizations (including the League of Nations and the Conference of American States), defending Sierran interests and citizens, supporting Sierran financial development and investment abroad, promoting Sierra's international trade, and providing humanitarian assistance to other countries. The Ministry is the oldest Cabinet-level ministry and was founded on November 27, 1858.

The Ministry is headquartered at the Mark Culler Building located at 430 N Broadway, Porciúncula, Gold Coast, 10000 in the Grand Park Center. The Ministry operates over 50 child agencies and departments, and is responsible for implementing the foreign policy of the Kingdom of Sierra. It derives its authority from Her Royal Majesty through delegation of her royal prerogative vis-à-vis foreign relations and it is accountable to the Privy Council. The Ministry's leadership, headed by the Minister of Foreign Affairs, reports to Her Royal Majesty's Government on all matters relating to foreign affairs and diplomatic efforts. The Ministry receives most of its funding from the House Committee of Appropriations' Subcommittee on Defense, Foreign Affairs, and Justice and is regulated by the Senate and House Committees on Foreign Relations and Title 14 of the Sierra Federal Code.

According to convention, the Minister of Foreign Affairs must be a member of Parliament from the House of Commons. Generally, a high-ranking MP who is part of the governing party or coalition is voted by their peers in the House and confirmed in the Senate to fulfill this requirement. This position is considered the most prestigious position in the Cabinet, as the Minister of Foreign Affairs officially ranks just below the Deputy Prime Minister according to the Sierran civilian order of precedence. The Minister of Foreign Affairs is the chief executive of the ministry and runs its day-to-day operations, and is assisted by the Deputy Minister of Foreign Affairs. The Ministry of Foreign Affairs Chief of Staff is the third-highest-ranking official in the ministry and due to its non-partisan nature (as opposed to the Minister and Deputy Minister), is appointed based on merit by the civil service system rather than elected by House members.
