The prime minister of Pakistan is the head of government of the Islamic Republic of Pakistan. Executive authority is vested in the prime minister-led and appointed cabinet, with the president of Pakistan serving as the nominal head of executive and state. The prime minister is often the leader of the party or the coalition with a majority in the lower house of the federal parliament, the National Assembly, where he serves as leader of the House. Prime minister holds office by virtue of their ability to command the confidence of the National Assembly. The prime minister is designated as the "chief executive of the Islamic Republic".
Pakistan's prime minister leads the executive branch of the federal government, oversees the state economy, leads the National Assembly, heads the Council of Common Interests as well as the Cabinet, and is charged with leading the National Command Authority over Pakistan's nuclear weapons arsenal. This position places its holder in leadership of the nation and in control over all matters, both internal affairs and foreign policy. The prime minister is elected by the members of the National Assembly and is therefore usually the leader of the majority party in the parliament. The Constitution of Pakistan vests executive powers in the prime minister, who is responsible for appointing the Cabinet as well as running the executive branch, taking and authorizing executive decisions, appointments, and recommendations that require prime ministerial confirmation.
