This is a graphical timeline of prime ministers of Great Britain and the United Kingdom from when the first prime minister of Great Britain in the modern sense, Robert Walpole, took office in 1721, until the present day.
From 1801 until 1922, British prime ministers also held the office for the whole of Ireland.
This timeline shows most of the early life, the political career and death of each prime minister of the United Kingdom from 1846. The first prime minister was Robert Walpole in the early 18th century ( Dickinson 1973 ).
Unlike countries where the leader is elected directly to the highest political office of a separate executive, the prime minister must first establish a political career in the UK Parliament and typically serves many years in the House of Commons before becoming prime minister, and in some cases for many years afterwards.
Since the Marquess of Salisbury in 1895, all time in parliamentary service before being prime minister has been in the House of Commons, apart from Sir Alec Douglas-Home's period as a member of the Government while in the House of Lords (1951–63; though he was previously the elected member for Lanark, 1931–1945). After becoming prime minister, Douglas-Home returned to the Commons by winning a by-election on the recess death of MP Gilmour Leburn.
Uniquely, Cameron's brief parliamentary activity as Foreign Secretary from November 2023 to July 2024 was served while a member of the House of Lords.
The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet, and selects its ministers. As modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, they sit as members of Parliament.
The chancellor of the exchequer, often abbreviated to chancellor, is a senior minister of the Crown within the Government of the United Kingdom, and head of Treasury. As one of the four Great Offices of State, the chancellor is a high-ranking member of the British Cabinet.
The Liberal Unionist Party was a British political party that was formed in 1886 by a faction that broke away from the Liberal Party. Led by Lord Hartington and Joseph Chamberlain, the party established a political alliance with the Conservative Party in opposition to Irish Home Rule. The two parties formed the ten-year-long coalition Unionist Government 1895–1905 but kept separate political funds and their own party organisations until a complete merger between the Liberal Unionist and the Conservative parties was agreed to in May 1912.
The Cabinet of the United Kingdom is the senior decision-making body of the Government of the United Kingdom. A committee of the Privy Council, it is chaired by the Prime Minister and its members include Secretaries of State and senior Ministers of State. Members of the Cabinet are appointed by the Prime Minister and are by convention chosen from members of the two houses of the Parliament of the United Kingdom, the House of Commons and the House of Lords.
John Russell, 1st Earl Russell, known as Lord John Russell before 1861, was a British Whig and Liberal statesman who served as Prime Minister of the United Kingdom from 1846 to 1852 and again from 1865 to 1866.
Sir Joseph Austen Chamberlain was a British statesman, son of Joseph Chamberlain and older half-brother of Prime Minister Neville Chamberlain. He served as a Member of Parliament (MP) for 45 years, as Chancellor of the Exchequer (twice) and was briefly Conservative Party leader before serving as Foreign Secretary.
The 1900 United Kingdom general election was held between 26 September and 24 October 1900, following the dissolution of Parliament on 25 September. Also referred to as the Khaki Election, it was held at a time when it was widely believed that the Second Boer War had effectively been won.
A parliamentary private secretary (PPS) is a member of Parliament (MP) in the United Kingdom who acts as an unpaid assistant to a government minister or a shadow minister. They are selected from backbench MPs as the "eyes and ears" of the minister in the House of Commons.
In the United Kingdom there are at least six Lords Commissioners of His Majesty's Treasury, serving as a commission for the ancient office of Treasurer of the Exchequer. The board consists of the First Lord of the Treasury, the Second Lord of the Treasury, and four or more junior lords acting as whips in the House of Commons to whom this title is usually applied.
The third Gladstone ministry was one of the shortest-lived ministries in British history. It was led by William Ewart Gladstone of the Liberal Party upon his reappointment as Prime Minister of the United Kingdom by Queen Victoria. It lasted five months until July 1886.
The article lists the records of prime ministers of the United Kingdom since 1721.
The Conservative Party is the oldest political party in the United Kingdom and arguably the world. The current party was first organised in the 1830s and the name "Conservative" was officially adopted, but the party is still often referred to as the Tory party. The Tories had been a coalition that often formed the government from 1760 until the Reform Act 1832. Modernising reformers said the traditionalistic party of "Throne, Altar and Cottage" was obsolete, but in the face of an expanding electorate from the 1830s to 1860s, it held its strength among royalists, devout Anglicans and landlords and their tenants.
The leader of the Conservative Party is the highest position within the United Kingdom's Conservative Party. The current holder of the position is Kemi Badenoch, who was elected to the position on 2 November 2024, following her victory against Robert Jenrick in the party's leadership election.
The Members' Lobby is a hallway in the Palace of Westminster used by members of the House of Commons, the lower house of the Parliament of the United Kingdom. Members of Parliament may congregate here for discussions while not dealing with other business.
The position of Prime Minister of the United Kingdom was not created as a result of a single action; it evolved slowly and organically over three hundred years due to numerous Acts of Parliament, political developments, and accidents of history.
