Oath of officeAn oath of office is an oath or affirmation a person takes before assuming the duties of an office, usually a position in government or within a religious body, although such oaths are sometimes required of officers of other organizations. Such oaths are often required by the laws of the state, religious body, or other organization before the person may actually exercise the powers of the office or organization. It may be administered at an inauguration, coronation, enthronement, or other ceremony connected with the taking up of office itself, or it may be administered privately.
Westminster systemThe Westminster system or Westminster model is a type of parliamentary government that incorporates a series of procedures for operating a legislature, first developed in England. Key aspects of the system include an executive branch made up of members of the legislature, and that is responsible to the legislature; the presence of parliamentary opposition parties; and a ceremonial head of state who is different from the head of government. The term comes from the Palace of Westminster, the current seat of the Parliament of the United Kingdom.
Head of governmentThe head of government is the highest or the second-highest official in the executive branch of a sovereign state, a federated state, or a self-governing colony, autonomous region, or other government who often presides over a cabinet, a group of ministers or secretaries who lead executive departments. In diplomacy, "head of government" is differentiated from "head of state" although in some countries, for example the United States, they are the same person.
Commonwealth Heads of Government MeetingThe Commonwealth Heads of Government Meeting (CHOGM; ˈtʃɒgəm orˈtʃəʊm) is a biennial summit meeting of the governmental leaders from all Commonwealth nations. Despite the name, the head of state may be present in the meeting instead of the head of government, especially among semi-presidential states. Every two years the meeting is held in a different member state and is chaired by that nation's respective prime minister or president, who becomes the Commonwealth Chair-in-Office until the next meeting.
Parliamentary systemA parliamentary system, or parliamentarian democracy, is a system of democratic governance of a state (or subordinate entity) where the executive derives its democratic legitimacy from its ability to command the support ("confidence") of the legislature, typically a parliament, to which it is accountable. In a parliamentary system, the head of state is usually a person distinct from the head of government.
Presidential systemA presidential system, or single executive system, is a form of government in which a head of government, typically with the title of president, leads an executive branch that is separate from the legislative branch in systems that use separation of powers. This head of government is in most cases also the head of state. In a presidential system, the head of government is directly or indirectly elected by a group of citizens and is not responsible to the legislature, and the legislature cannot dismiss the president except in extraordinary cases.
Cabinet (government)A cabinet is a body of high-ranking state officials, typically consisting of the executive branch's top leaders. Members of a cabinet are usually called cabinet ministers or secretaries. The function of a cabinet varies: in some countries, it is a collegiate decision-making body with collective responsibility, while in others it may function either as a purely advisory body or an assisting institution to a decision-making head of state or head of government.
RepublicA republic, based on the Latin phrase res publica ('public affair'), is a state in which political power rests with the public and their representatives—in contrast to a monarchy. Representation in a republic may or may not be freely elected by the general citizenry. In many historical republics, representation has been based on personal status and the role of elections has been limited.
Reserve powerIn a parliamentary or semi-presidential system of government, a reserve power, also known as discretionary power, is a power that may be exercised by the head of state without the approval of another branch or part of the government. Unlike in a presidential system of government, the head of state is generally constrained by the cabinet or the legislature in a parliamentary system, and most reserve powers are usable only in certain exceptional circumstances.
Executive (government)The executive, also referred as the executive branch or executive power, is the term commonly used to describe that part of government which enforces the law, and has overall responsibility for the governance of a state. The scope of executive power varies greatly depending on the political context in which it emerges, and it can change over time in a given country. In democratic countries, the executive often exercises broad influence over national politics, though limitations are often applied to the executive.
