House of Lords in the context of "Senate of Canada"

The constitution of the United Kingdom comprises the written and unwritten arrangements that establish the United Kingdom of Great Britain and Northern Ireland as a political body. Unlike in most countries, no official attempt has been made to codify such arrangements into a single document, thus it is known as an uncodified constitution. This enables the constitution to be easily changed as no provisions are formally entrenched.

The Supreme Court of the United Kingdom and its predecessor, the Appellate Committee of the House of Lords, have recognised and affirmed constitutional principles such as parliamentary sovereignty, the rule of law, democracy, and upholding international law. It also recognises that some Acts of Parliament have special constitutional status. These include the Magna Carta, which in 1215 required the King to call a "common counsel" (now called Parliament) to represent the people, to hold courts in a fixed place, to guarantee fair trials, to guarantee free movement of people, to free the church from the state, and to guarantee rights of "common" people to use the land. After the Glorious Revolution, the Bill of Rights 1689 and the Claim of Right Act 1689 cemented Parliament's position as the supreme law-making body, and said that the "election of members of Parliament ought to be free". The Treaty of Union in 1706 and the Acts of Union 1707 united the Kingdoms of England, Wales and Scotland, the Acts of Union 1800 joined Ireland, but the Irish Free State separated after the Anglo-Irish Treaty in 1922, leaving Northern Ireland within the UK. After struggles for universal suffrage, the UK guaranteed every adult citizen over 21 years the equal right to vote in the Representation of the People (Equal Franchise) Act 1928. After World War II, the UK became a founding member of the Council of Europe to uphold human rights, and the United Nations to guarantee international peace and security. The UK was a member of the European Union, joining its predecessor in 1973, but left in 2020. The UK is also a founding member of the International Labour Organization and the World Trade Organization to participate in regulating the global economy.

The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body of the United Kingdom, and may also legislate for the Crown Dependencies and the British Overseas Territories. Since 1999, varying degree of powers have been devolved to the devolved national parliaments of Northern Ireland, Scotland, and Wales. Each devolved parliament has different devolved powers, with Scotland being the most powerful amongst the three devolved parliaments. The central UK Parliament retains the power to legislate in reserved matters, including broadcasting, defence, and currency.

It meets at the Palace of Westminster in London. Parliament possesses legislative supremacy and thereby holds ultimate power over all other political bodies in the United Kingdom and the Overseas Territories. While Parliament is bicameral, it has three parts: the sovereign, the House of Lords, and the House of Commons. The three parts acting together to legislate may be described as the King-in-Parliament. The Crown normally acts on the advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation.

The Palace of Westminster is the meeting place of the Parliament of the United Kingdom and is located in London, England. It is commonly called the Houses of Parliament after the House of Commons and the House of Lords, the two legislative chambers which occupy the building. The palace is one of the centres of political life in the United Kingdom; "Westminster" has become a metonym for the UK Parliament and the British Government, and the Westminster system of government commemorates the name of the palace. The Elizabeth Tower of the palace, nicknamed Big Ben, is a landmark of London and the United Kingdom in general. The palace has been a Grade I listed building since 1970 and part of a UNESCO World Heritage Site since 1987.

The building was originally constructed in the eleventh century as a royal palace and was the primary residence of the kings of England until 1512, when a fire destroyed the royal apartments. The monarch moved to the adjacent Palace of Whitehall, but the remainder of the palace continued to serve as the home of the Parliament of England, which had met there since the 13th century. In 1834 a second, larger fire destroyed the majority of the palace, but the twelfth century Westminster Hall was saved and incorporated into the replacement building.

The House of Commons is the lower house of the Parliament of the United Kingdom. Like the upper house, the House of Lords, it meets in the Palace of Westminster in London, England. The House of Commons is an elected body consisting of 650 members known as members of Parliament (MPs), who are elected to represent constituencies by the first-past-the-post system and hold their seats until Parliament is dissolved.

The House of Commons of England began to evolve in the 13th and 14th centuries. In 1707 it became the House of Commons of Great Britain after the political union with Scotland, and from 1801 it also became the House of Commons for Ireland after the political union of Great Britain and Ireland. In 1922, the body became the House of Commons of the United Kingdom of Great Britain and Northern Ireland after the independence of the Irish Free State. Under the Parliament Acts 1911 and 1949, the Lords' power to reject legislation was reduced to a delaying power. The government is solely responsible to the House of Commons and the prime minister stays in office only as long as they retain the confidence of a majority of the Commons.

Whilst the House of Lords of the United Kingdom is the upper chamber of Parliament and has government ministers, for many centuries it had a judicial function. It functioned as a court of first instance for the trials of peers and for impeachments, and as a court of last resort in the United Kingdom and prior, the Kingdom of Great Britain and the Kingdom of England.

Appeals were technically not to the House of Lords, but rather to the King-in-Parliament. The Appellate Jurisdiction Act 1876 devolved the appellate functions of the House to an Appellate Committee, composed of Lords of Appeal in Ordinary (informally referred to as Law Lords). They were then appointed by the Lord Chancellor in the same manner as other judges.

The Parliament of England was the legislature of the Kingdom of England from the 13th century until 1707 when it was replaced by the Parliament of Great Britain. Parliament evolved from the great council of bishops and peers that advised the English monarch. Great councils were first called Parliaments during the reign of Henry III (r. 1216–1272). By this time, the king required Parliament's consent to levy taxation.

Originally a unicameral body, a bicameral Parliament emerged when its membership was divided into the House of Lords and House of Commons, which included knights of the shire and burgesses. During Henry IV's reign, the role of Parliament expanded beyond the determination of taxation policy to include the right to petition, which essentially enabled English citizens to petition the body to address complaints in their local towns and counties. By this time, citizens were given the power to vote to elect their representatives—the burgesses—to the House of Commons.

Nobility is a social class found in many societies that have an aristocracy. It is normally appointed by and ranked immediately below royalty. Nobility has often been an estate of the realm with many exclusive functions and characteristics. The characteristics associated with nobility may constitute substantial advantages over or relative to non-nobles or simply formal functions (e.g., precedence), and vary by country and by era. Membership in the nobility, including rights and responsibilities, is typically hereditary and patrilineal.

Membership in the nobility has historically been granted by a monarch or government, and acquisition of sufficient power, wealth, ownerships, or royal favour has occasionally enabled commoners to ascend into the nobility.

His Majesty's Government, abbreviated to HM Government or otherwise UK Government, is the central executive authority of the United Kingdom of Great Britain and Northern Ireland. The government is led by the prime minister (Keir Starmer since 5 July 2024) who selects all the other ministers. The government is currently supported by the Labour party, which has had a majority in the House of Commons since 2024. The prime minister and his most senior ministers belong to the supreme decision-making committee, known as the Cabinet.

Ministers of the Crown are responsible to the House in which they sit; they make statements in that House and take questions from members of that House. For most senior ministers this is usually the elected House of Commons rather than the House of Lords. The government is dependent on Parliament to make primary legislation, and general elections are held at least once every five years to elect a new House of Commons, unless the prime minister advises the monarch to dissolve Parliament, in which case an election may be held sooner. After an election, the monarch selects as prime minister the leader of the party most likely to command the confidence of the House of Commons, usually by possessing a majority of MPs.

David William Donald Cameron, Baron Cameron of Chipping Norton (born 9 October 1966), is a British politician who served as Prime Minister of the United Kingdom from 2010 to 2016. Until 2015, he led the first coalition government in the UK since 1945 and resigned after a referendum supported the country's leaving the European Union. After his premiership, he served as Foreign Secretary in the government of prime minister Rishi Sunak from 2023 to 2024. Cameron was Leader of the Conservative Party from 2005 to 2016 and served as Leader of the Opposition from 2005 to 2010. He was Member of Parliament (MP) for Witney from 2001 to 2016, and has been a member of the House of Lords since November 2023. Cameron identifies as a one-nation conservative and has been associated with both economically liberal and socially liberal policies.

Born in London to an upper-middle-class family, Cameron was educated at Eton College and Brasenose College, Oxford. After becoming an MP in 2001, he served in the opposition Shadow Cabinet under Conservative leader Michael Howard, and succeeded Howard in 2005. Following the 2010 general election, negotiations led to Cameron becoming prime minister as the head of a coalition government with the Liberal Democrats.
