Andy Burnham fears dividing Labour if he pushes ahead with Ed Miliband as Chancellor

Glossary: key terms in British politics

A reference guide to the vocabulary of UK political life — the terms, institutions and conventions that shape how Westminster works.

The Whip

A party official in Parliament responsible for managing MPs' or peers' voting behaviour and parliamentary attendance. The term derives from fox-hunting, where the "whipper-in" kept the hounds in line. Government and opposition parties each have a Chief Whip and a team of junior whips. Instructions to vote are issued in writing and graded by urgency: a one-line whip is advisory, a two-line whip expects attendance, and a three-line whip is a mandatory instruction — defying it risks losing the whip entirely, meaning effective expulsion from the parliamentary party. The whipping system is the mechanism through which party discipline is enforced, and the Chief Whip is one of the most consequential roles in any government.

PMQs

Prime Minister's Questions — a weekly session held in the House of Commons every Wednesday at noon when Parliament is sitting. The Leader of the Opposition asks six questions, backbench MPs from all parties ask further questions, and the Prime Minister is expected to answer without advance notice of the questions. PMQs is the most high-profile moment in the parliamentary week and is watched closely for signs of the PM's authority, the effectiveness of the opposition, and the mood of the governing party. Critics argue it has become theatrical rather than genuinely scrutinising; defenders contend it is one of the few moments when the head of government faces direct, unscripted challenge.

The Lords

The House of Lords — the upper chamber of the UK Parliament. Unlike the elected Commons, the Lords is an unelected body composed of life peers (appointed by successive governments on the advice of the Prime Minister), hereditary peers (a small residual group following the 1999 reforms), and Lords Spiritual (senior Church of England bishops). The Lords can amend and delay legislation but cannot ultimately block a bill that has passed the Commons — the Parliament Acts limit its power of obstruction to one year for most bills. The Lords performs significant scrutiny and revision work on legislation, and its committees produce detailed reports on policy. Its composition and the basis of its legitimacy are subjects of continuing constitutional debate.

Devolution

The transfer of legislative and executive powers from Westminster to devolved institutions in Scotland, Wales and Northern Ireland. The Scottish Parliament, established in 1999, has the broadest powers — including over health, education, justice, some taxation and many other areas. The Welsh Senedd has progressively received more powers and now legislates across most domestic policy areas. The Northern Ireland Assembly operates under the terms of the Good Friday Agreement and has a distinctive power-sharing structure between unionist and nationalist parties. Devolution has not resolved the underlying constitutional tensions: the Scottish independence question remains live, and disputes over the boundaries of devolved competence — particularly in relation to Brexit and EU law — are a recurring source of friction.

First Past the Post

The electoral system used for UK general elections: the candidate with the most votes in each constituency wins the seat, regardless of whether they have achieved an outright majority. Because votes for losing candidates count for nothing in terms of seats, FPTP can produce very large parliamentary majorities on modest national vote shares — and substantial changes in seats from relatively small swings in votes. Critics argue it misrepresents the distribution of opinion in the country; supporters contend it produces strong, stable majority governments and a clear link between MPs and their constituents. The distorting effects were starkly illustrated in 2024, when Labour won a large parliamentary majority while receiving a historically low share of the national vote.

The OBR

The Office for Budget Responsibility — the independent fiscal watchdog established in 2010 to scrutinise the government's economic and fiscal forecasts. Before each Budget and Autumn Statement, the OBR produces official forecasts for economic growth, inflation, borrowing and debt that the Chancellor must use as the basis for fiscal decisions. The OBR's forecasts carry considerable authority and its judgements — particularly on whether the government is on track to meet its fiscal rules — can significantly constrain what a Chancellor is able to announce. When the OBR produces forecasts that show deteriorating public finances, the government faces pressure to raise taxes or cut spending to meet its self-imposed rules.

The Bank of England

The UK's central bank, responsible for monetary policy (setting interest rates), financial stability and prudential regulation of banks. The Bank's Monetary Policy Committee meets eight times a year to set the base rate — the interest rate at which it lends to commercial banks, which flows through to mortgage rates, savings rates and the cost of borrowing across the economy. The MPC's decisions are the most directly consequential economic announcements most British households experience: a rate rise increases mortgage payments for millions of variable-rate borrowers. The Bank operates independently of the government on monetary policy — a separation deliberately designed to prevent governments from manipulating rates for electoral advantage.

Manifesto commitment

A specific policy promise made by a political party in its general election manifesto — the document setting out what a party intends to do if it wins power. Manifesto commitments carry particular political weight in the UK system because the Lords is expected by convention (the Salisbury Convention) not to block legislation implementing measures that were in the governing party's manifesto. Breaking a manifesto commitment is a significant political embarrassment — opposition parties and media scrutinise compliance closely. Not all manifesto commitments are equally binding: some are aspirational, some are costed, some are conditional on economic circumstances, and governments regularly find reasons why commitments cannot be honoured in the form originally promised.

The Treasury

The UK government's economics and finance ministry, formally HM Treasury. Headed by the Chancellor of the Exchequer, the Treasury controls public spending allocations across government, tax policy, debt management and the overall framework of fiscal rules. Its power over other departments — which must negotiate with the Treasury for their budgets in spending reviews — makes it the most powerful ministry in Whitehall after the Cabinet Office. The Treasury's influence extends beyond its formal remit: it tends to impose a cautious, fiscal-conservative discipline across government that can conflict with more expansionary departmental ambitions. The relationship between the Prime Minister and the Chancellor is one of the most consequential in any government.

Select committees

Parliamentary committees of backbench MPs that scrutinise the work of government departments and public bodies. Each major government department has a corresponding select committee — the Treasury Committee, the Health Committee, the Foreign Affairs Committee, and so on. Select committees can call ministers and officials to give evidence, demand documents, publish reports and draw public attention to government failures or policy problems. They cannot force the government to change policy, but their reports and hearings carry genuine weight and can create significant political pressure. Select committee chairs — elected by MPs — have become increasingly prominent political figures in their own right, particularly when they are willing to challenge their own party's government.

The Autumn Statement

A major fiscal event held in autumn (sometimes called the Autumn Budget) in which the Chancellor of the Exchequer updates Parliament on the state of the public finances and announces changes to taxation and spending. Alongside the Spring Budget, the Autumn Statement is one of the two primary fiscal events of the year. The OBR publishes updated forecasts at the same time, and the Chancellor's announcements must be set against those forecasts. The name has varied — it has been called the Autumn Statement, the Autumn Budget and the Pre-Budget Report at different points — reflecting different governments' preferences for how to frame the event. For most households, it is the moment when tax changes and spending decisions with direct personal consequences are announced.

Confidence and supply

An arrangement in which a smaller party agrees to support a minority government in votes of confidence and budget votes — sufficient to keep it in office — without formally joining a coalition. The smaller party maintains its independence and does not take ministerial positions, but commits not to bring down the government on key votes. This is a more limited arrangement than a full coalition: the two parties do not share collective Cabinet responsibility and can disagree publicly on other issues. The DUP's support for Theresa May's minority government from 2017 to 2019 is the most recent British example. Confidence and supply arrangements are inherently fragile and typically reflect the arithmetic of a hung parliament rather than ideological agreement.

The civil service

The permanent, politically neutral bureaucracy that staffs UK government departments and carries out the day-to-day work of government. Civil servants serve successive governments of different parties, providing institutional continuity and policy expertise. Senior civil servants — permanent secretaries and director generals — advise ministers on policy, manage the implementation of decisions and ensure legal and procedural compliance. The civil service is formally neutral, but its culture tends toward caution and institutional conservatism that can frustrate governments wanting rapid change. The relationship between ministers and their departments has been a source of tension in every recent government, with ministers and officials sometimes publicly blaming each other when policies fail.

Ping-pong

The informal term for the process of legislative amendment between the two Houses of Parliament. When the House of Lords amends a bill passed by the Commons, it returns to the Commons for consideration of those amendments. The Commons may accept the Lords' changes, reject them, or propose alternatives. The bill then goes back to the Lords, which can accept the Commons position or insist on its amendments. This exchange — the bill passing back and forth between the chambers — continues until agreement is reached or the government invokes the Parliament Acts to override Lords opposition. The term captures the rapid back-and-forth character of the process in its final stages, which can produce rapid and sometimes messy legislative outcomes in the closing days of a parliamentary session.

The Lobby

The group of political journalists who are accredited to the Houses of Parliament and receive exclusive briefings from government and party press operations. Lobby journalists attend twice-daily briefings from the Prime Minister's official spokesperson and receive other briefings from party spin doctors and ministerial advisers, often on a non-attributable basis. The Lobby system gives political journalists access to information in return for accepting the ground rules set by their sources — a trade-off that critics argue compromises independence. Coverage sourced to "a government source" or "a senior Conservative" typically originates in Lobby briefings. Understanding the Lobby system helps explain why political coverage often reflects the internal spin operations of parties rather than independent reporting of what is actually happening.
