The politics of Papua New Guinea takes place in a framework of a parliamentary representative democratic multi-party system, whereby the Prime Minister is the head of government. Papua New Guinea is an independent Commonwealth realm, with a governor-general, nominated by the National Parliament, acting as head of state. Executive power is exercised by the government. Legislative power is vested in both the government and parliament.
Constitutional safeguards include freedom of speech, press, worship, movement, and association. The judiciary is independent of the executive and the legislature.
The Head of the Commonwealth, or simply Queen of Papua New Guinea, is represented in Papua New Guinea by a governor general who acts on the advice of the prime minister and the cabinet. The Governor-General of Papua New Guinea is elected by parliament.
The governments of Papua New Guinea are characterized by weak political parties and highly unstable parliamentary coalitions. The prime minister, elected by Parliament, chooses the other members of the cabinet. Each ministry is headed by a cabinet member, who is assisted by a permanent secretary, a career public servant, who directs the staff of the ministry. The cabinet consists members, including the Prime Minister and ministers of executive departments. They answer politically to parliament.
