These are lists of incumbents, including heads of states or of subnational entities.
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 United Kingdom is a constitutional monarchy which, by legislation and convention, operates as a unitary parliamentary democracy. A hereditary monarch, currently King Charles III, serves as head of state while the Prime Minister of the United Kingdom, currently Sir Keir Starmer since 2024, serves as the elected head of government.
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.
Devolution is the statutory delegation of powers from the central government of a sovereign state to govern at a subnational level, such as a regional or local level. It is a form of administrative decentralization. Devolved territories have the power to make legislation relevant to the area, thus granting them a higher level of autonomy.
The Leader of the Opposition is a title traditionally held by the leader of the largest political party not in government, typical in countries utilizing the parliamentary system form of government. The leader of the opposition is typically seen as an alternative prime minister, premier, first minister, or chief minister to the incumbent; in the Westminster system, they head a rival alternative government known as the shadow cabinet or opposition front bench. The same term is also used to refer to the leader of the largest political party that is not in government in subnational state, provincial, and other regional and local legislatures.
The administrative geography of the United Kingdom is complex, multi-layered and non-uniform. The United Kingdom, a sovereign state to the northwest of continental Europe, consists of England, Northern Ireland, Scotland and Wales. For local government in the United Kingdom, England, Northern Ireland, Scotland and Wales each have their own system of administrative and geographic demarcation. Consequently, there is "no common stratum of administrative unit encompassing the United Kingdom".
The Taoiseach is the head of government of the Republic of Ireland, whose territory covers the island of Ireland, save Northern Ireland, which is a self-governing part of the United Kingdom.
A deputy prime minister or vice prime minister is, in some countries, a government minister who can take the position of acting prime minister when the prime minister is temporarily absent. The position is often likened to that of a vice president, as both positions are "number two" offices, but there are some differences.
A minister-president or minister president is the head of government in a number of European countries or subnational governments with a parliamentary or semi-presidential system of government where they preside over the council of ministers. It is an alternative term for prime minister, premier, chief minister, or first minister and very similar to the title of president of the council of ministers.
The premier of Yukon is the first minister and head of government for the Canadian territory of Yukon. The post is the territory's head of government, although its powers are considerably more limited than that of a provincial premier. The office was established in 1978 when most authority was devolved from the appointed commissioner to the leader of the party that had the confidence of the Yukon Legislative Assembly; for the year immediately prior to this, that leader was one of the members serving with the commissioner's Executive Committee.
The commissioner of Yukon is the representative of the Government of Canada in the Canadian federal territory of Yukon. The commissioner is appointed by the federal government and, in contrast to the governor general of Canada or the lieutenant governors of the Canadian provinces, is not a viceroy and therefore not a direct representative of the Canadian monarch in the territory eo ipso.
A member of the Legislative Assembly (MLA) is a representative elected to sit in a legislative assembly. The term most commonly refers to members of the legislature of a federated state or an autonomous region, but is also used for several national legislatures.
Chief executive is a term used for a head of government that allows its holder to perform various functions. The term can also apply to heads of state as well, though it is less common. The term may refer to the title of the position, but many constituencies place this power in a position with a different title.
The Ministry of Justice (MoJ) is a ministerial department of the Government of the United Kingdom. It is headed by the Secretary of State for Justice and Lord Chancellor. Its stated priorities are to reduce re-offending and protect the public, to provide access to justice, to increase confidence in the justice system, and to uphold people's civil liberties. The Secretary of State is the minister responsible to Parliament for the judiciary, the court system, prisons, and probation in England and Wales, with some additional UK-wide responsibilities, e.g., the UK Supreme Court and judicial appointments by the Crown. The department is also responsible for areas of constitutional policy not transferred in 2010 to the Deputy Prime Minister, human rights law, and information rights law across the UK.
A term of office, electoral term, or parliamentary term is the length of time a person serves in a particular elected office. In many jurisdictions there is a defined limit on how long terms of office may be before the officeholder must be subject to re-election. Some jurisdictions exercise term limits, setting a maximum number of terms an individual may hold in a particular office.
A dominion was any of several largely self-governing countries of the British Empire, once known collectively as the British Commonwealth of Nations. Progressing from colonies, their degrees of colonial self-governance increased unevenly over the late 19th century through the 1930s. Vestiges of empire lasted in some dominions well into the late 20th century. With the evolution of the British Empire following the 1945 conclusion of the Second World War into the modern Commonwealth of Nations, finalised in 1949, the dominions became independent states, either as Commonwealth republics or Commonwealth realms.
In the United Kingdom, devolution is the Parliament of the United Kingdom's statutory granting of a greater level of self-government to the Scottish Parliament, the Senedd, the Northern Ireland Assembly and the London Assembly and to their associated executive bodies: the Scottish Government, the Welsh Government, the Northern Ireland Executive and in England, the Greater London Authority and combined authorities.
In the United Kingdom, intergovernmental relations refers to the relationship, cooperation, and engagement between the central UK Government and the devolved administrations of the Scottish Government, Welsh Government and Northern Ireland Executive.
