Political authorities hold positions of power or influence within a system of government. Although some are exclusive to one or another form of government, many exist within several types.
Politics in Estonia takes place in a framework of a parliamentary representative democratic republic, whereby the Prime Minister of Estonia is the head of government, and of a multi-party system. Legislative power is vested in the Estonian parliament. Executive power is exercised by the government, which is led by the prime minister. The judiciary is independent of the executive and the legislature. Estonia is a member of the United Nations, the European Union, and NATO.
A prime minister or chief of cabinet is the head of the cabinet and the leader of the ministers in the executive branch of government, often in a parliamentary or semi-presidential system. A prime minister is not the head of state, but rather the head of government, serving as the chief of the executive under either a monarch or a president in a republican form of government.
The premier of Queensland is the head of government in the Australian state of Queensland.
The politics of Vietnam is dominated by a single party under an authoritarian system, the Communist Party of Vietnam (CPV). The President of Vietnam is the head of state, and the Prime Minister of Vietnam is the head of government. Both of these offices are separate from the General Secretary of the Communist Party of Vietnam, who leads the CPV and is head of the Politburo and the Central Military Commission. The General Secretary is thus the de facto highest position in the Vietnamese politics.
The 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 separate from the head of government. The term derives from the Palace of Westminster, which has been the seat of the Westminster Parliament in England and later the United Kingdom since the 13th century. The Westminster system is often contrasted with the presidential system that originated in the United States, or with the semi-presidential system, based on the government of France.
In the executive branch, the head of government is the highest or the second-highest official 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.
The prime minister of Italy, officially the president of the Council of Ministers, is the head of government of the Italian Republic. The office of president of the Council of Ministers is established by articles 92–96 of the Constitution of Italy; the president of the Council of Ministers is appointed by the president of the Republic and must have the confidence of the Parliament to stay in office.
The prime minister of Croatia, officially the president of the government of the Republic of Croatia, is Croatia's head of government, and is de facto the most powerful and influential state officeholder in the Croatian system of government. Following the first-time establishment of the office in 1945, the 1990–2000 semi-presidential period is the only exception where the president of Croatia held de facto executive authority. In the formal Croatian order of precedence, however, the position of prime minister is the third highest state office, after the president of the Republic and the speaker of the Parliament.
The President of the Socialist Republic of Vietnam is the head of state of Vietnam, elected by the National Assembly of Vietnam from its delegates. Since Vietnam is a one-party state, candidates for the post are nominated by the Central Committee of the Communist Party of Vietnam. The officeholder is generally considered to hold the second-highest position in the political system, practically after the General Secretary of the Communist Party of Vietnam. As head of state, the President represents Vietnam both domestically and internationally, and maintains the regular and coordinated operation and stability of the national government and safeguards the independence and territorial integrity of the country.

A minister is a politician who heads a ministry, making and implementing decisions on policies in conjunction with the other ministers. In some jurisdictions the head of government is also a minister and is designated the 'prime minister', 'premier', 'chief minister', 'chancellor' or other title.
A permanent secretary is the most senior civil servant of a department or ministry charged with running the department or ministry's day-to-day activities. Permanent secretaries are the non-political civil service chief executives of government departments or ministries, who generally hold their position for a number of years at a ministry as distinct from the changing political secretaries of state to whom they report and provide advice. The role originated in the civil service of the United Kingdom and has been adopted in several Commonwealth countries as well as other countries influenced by the Westminster system.
The government of the People's Republic of China is based on a system of people's congress within the parameters of a unitary communist state, in which the ruling Chinese Communist Party (CCP) enacts its policies through people's congresses. This system is based on the principle of unified state power, in which the legislature, the National People's Congress (NPC), is constitutionally enshrined as "the highest state organ of power." As China's political system has no separation of powers, there is only one branch of government which is represented by the legislature. The CCP through the NPC enacts unified leadership, which requires that all state organs, from the Supreme People's Court to the President of China, are elected by, answerable to, and have no separate powers than those granted to them by the NPC. By law, all elections at all levels must adhere to the leadership of the CCP. The CCP controls appointments in all state bodies through a two-thirds majority in the NPC. The remaining seats are held by nominally independent delegates and eight minor political parties, which are non-oppositional and support the CCP. All government bodies and state-owned enterprises have internal CCP committees that lead the decision-making in these institutions.

In a governmental system, a party leader acts as the official representative of their political party, either to a legislature or to the electorate.

A cabinet in governing is a group of people with the constitutional or legal task to rule a country or state, or advise a head of state, usually from the executive branch. Their members are known as ministers and secretaries and they are often appointed by either heads of state or government. Cabinets are typically the body responsible for the day-to-day management of the government and response to sudden events, whereas the legislative and judicial branches work in a measured pace, in sessions according to lengthy procedures.
