The United Kingdom is a sovereign state located off the north-western coast of continental Europe. With a total area of approximately 244,376 square kilometres (94,354 sq mi), the UK occupies the major part of the British Isles archipelago and includes the island of Great Britain, the north-eastern one-sixth of the island of Ireland and many smaller surrounding islands. It is the world's 7th largest island country. The mainland areas lie between latitudes 49°N and 59°N, and longitudes 8°W to 2°E. The Royal Observatory, Greenwich, in south-east London, is the defining point of the Prime Meridian.
The politics of the United Kingdom functions within a constitutional monarchy where executive power is delegated by legislation and social conventions to a unitary parliamentary democracy. From this a hereditary monarch, currently King Charles III, serves as head of state while the Prime Minister of the United Kingdom, currently Rishi Sunak since 2022, serves as the elected head of government.
A unitary authority is a local authority responsible for all local government functions within its area or performing additional functions that elsewhere are usually performed by a higher level of sub-national government or the national government.
The legislatures of the United Kingdom are derived from a number of different sources. The Parliament of the United Kingdom is the supreme legislative body for the United Kingdom and the British overseas territories with Scotland, Wales and Northern Ireland each having their own devolved legislatures. Each of the three major jurisdictions of the United Kingdom has its own laws and legal system.
The United Kingdom has three distinctly different legal systems, each of which derives from a particular geographical area for a variety of historical reasons: English law, Scots law, Northern Ireland law, and, since 2007, calls for a fourth type, that of purely Welsh law as a result of Welsh devolution, with further calls for a Welsh justice system.
There has not been a government of England since 1707 when the Kingdom of England ceased to exist as a sovereign state, as it merged with the Kingdom of Scotland to form the Kingdom of Great Britain. The Kingdom of Great Britain continued from 1707 until 1801 when it merged with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland, which itself became the United Kingdom of Great Britain and Northern Ireland (UK) in 1922 upon independence for most of the island of Ireland.
The subdivisions of England constitute a hierarchy of administrative divisions and non-administrative ceremonial areas.
Politics of England forms the major part of the wider politics of the United Kingdom, with England being more populous than all the other countries of the United Kingdom put together. As England is also by far the largest in terms of area and GDP, its relationship to the UK is somewhat different from that of Scotland, Wales or Northern Ireland. The English capital London is also the capital of the UK, and English is the dominant language of the UK. Dicey and Morris (p26) list the separate states in the British Islands. "England, Scotland, Northern Ireland, the Isle of Man, Jersey, Guernsey, Alderney, and Sark.... is a separate country in the sense of the conflict of laws, though not one of them is a State known to public international law." But this may be varied by statute.
In the United Kingdom (UK), each of the electoral areas or divisions called constituencies elects one member to the House of Commons.
The counties of the United Kingdom are subnational divisions of the United Kingdom, used for the purposes of administrative, geographical and political demarcation. The older term, shire is historically equivalent to county. By the Middle Ages, county had become established as the unit of local government, at least in England. By the early 17th century, all of England, Wales, Scotland, and Ireland had been separated into counties. In Scotland shire was the only term used until after the Act of Union 1707.
The Lieutenancies Act 1997 is an Act of Parliament in the United Kingdom that defines areas that lord-lieutenants are appointed to in Great Britain. It came into force on 1 July 1997.
The wards and electoral divisions in the United Kingdom are electoral districts at sub-national level, represented by one or more councillors. The ward is the primary unit of English electoral geography for civil parishes and borough and district councils, the electoral ward is the unit used by Welsh principal councils, while the electoral division is the unit used by English county councils and some unitary authorities. Each ward/division has an average electorate of about 5,500 people, but ward population counts can vary substantially. As of 2021 there are 8,694 electoral wards/divisions in the UK. An average area of wards in the United Kingdom is 27 km2.
Since 1922, the United Kingdom has been made up of four countries: England, Scotland, Wales and Northern Ireland. The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom. Some statistical summaries, such as those for the twelve NUTS 1 regions of the UK, refer to Northern Ireland, Scotland, and Wales as "regions". With regard to Northern Ireland, Scotland and Wales particularly, the descriptive name one uses "can be controversial, with the choice often revealing one's political preferences".
The House of Commons Act 1949 was an Act of the Parliament of the United Kingdom that provided for the periodic review of the number and boundaries of parliamentary constituencies.
The regions of England, formerly known as the government office regions, are the highest tier of sub-national division in England. They were established in 1994 and follow the 1974–96 county borders. They are a continuation of the former 1940s standard regions which followed the 1889–1974 administrative county borders. Between 1994 and 2011, all nine regions had partly devolved functions; they no longer fulfil this role, continuing to be used for limited statistical purposes.

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, the Alternative Vote referendum also known as the UK-wide referendum on the Parliamentary voting system was a referendum that took place on 5 May 2011, on whether to change the system for electing the House of Commons, the lower house of the national Parliament at Westminster. In the result of a Yes vote, future United Kingdom general elections would have used the "Alternative Vote" (AV); in the event of a No vote, the voting system would remain the same, with the UK continuing to use the "First Past the Post" (FPTP) voting system. The votes cast in the referendum were first counted in each of 440 districts or electoral divisions across the country, which were then combined and declared at a regional level.
