UK Government and Politics: Complete Guide
Last updated: December 2025 | Reading time: 12 minutes | Essential for the Life in the UK Test
Why This Matters: Understanding how the UK government works is crucial for British
citizenship. Questions about Parliament, the Prime Minister, voting rights, and the UK's political system
appear frequently on the Life in the UK Test. This guide covers everything you need to know about British
democracy and governance.
The UK as a Constitutional Monarchy
The United Kingdom is a constitutional monarchy with a parliamentary democracy. This means that while the UK
has a monarch (currently King Charles III), the real power lies with Parliament and the elected government.
Unlike absolute monarchies where the king or queen has supreme power, Britain's monarch must act according
to rules set out in laws and conventions.
The UK doesn't have a single written document as its constitution. Instead, the British constitution is
"unwritten" - it consists of laws passed by Parliament, legal judgments, and traditions built up over
centuries. This flexible system has evolved gradually, allowing Britain to adapt without revolutions or
complete constitutional rewrites.
Key Principle: The UK operates on the principle of "parliamentary sovereignty," meaning
Parliament is the supreme legal authority and can create or end any law. No other body can override
Parliament's legislation.
The Monarch
The British monarchy is one of the oldest institutions in the country, with roots stretching back over a
thousand years. However, the monarch's role today is largely ceremonial and symbolic rather than political.
The Role of the Monarch
The monarch's duties include:
- Opening and dissolving Parliament: The monarch formally opens each session of
Parliament with the King's Speech (or Queen's Speech), though the speech is written by the government
and outlines its legislative plans.
- Royal Assent: All bills passed by Parliament must receive Royal Assent (the monarch's
approval) before becoming law. In practice, this is a formality - no monarch has refused Royal Assent
since 1708.
- Appointing the Prime Minister: The monarch asks the leader of the party with the most
MPs to form a government, but this is based on election results, not personal choice.
- Head of State: The monarch represents the UK at home and abroad, meets with foreign
dignitaries, and undertakes state visits.
- Head of the Church of England: The monarch holds the title "Defender of the Faith and
Supreme Governor of the Church of England."
- Head of the Armed Forces: The monarch is Commander-in-Chief, though military decisions
are made by the government.
- Head of the Commonwealth: The monarch serves as head of the Commonwealth, an
association of 56 independent countries.
Constitutional Role
Although the monarch has these formal powers (known as "royal prerogative"), in practice the monarch must act
on the advice of the Prime Minister and government ministers. The monarch remains politically neutral and
doesn't vote or stand for election. This principle is sometimes summarized as: the monarch "reigns but does
not rule."
The Line of Succession
The throne passes according to rules of succession. Since 2013, succession is determined by order of birth
regardless of gender - previously, male heirs took precedence over older sisters. The monarch must be
Protestant and in communion with the Church of England.
Test Tip: Remember that the monarch's role is ceremonial. Political power rests with
elected representatives. The monarch acts on the advice of the Prime Minister and cannot refuse to sign
bills into law in modern practice.
Parliament
Parliament is the supreme law-making body in the UK. It consists of three parts: the House of Commons, the
House of Lords, and the Monarch. However, when people talk about Parliament, they usually mean the first two
houses.
The House of Commons
The House of Commons is the more powerful of the two houses. It consists of 650 elected Members of Parliament
(MPs), each representing a geographical constituency (area) in the UK.
Key facts about the House of Commons:
- MPs are elected in general elections, which must be held at least every five years
- The political party with the most MPs usually forms the government
- The Commons can overrule the House of Lords on most matters
- All laws involving taxation and public spending must be approved by the Commons
- The Prime Minister and most government ministers are MPs
- The Speaker of the House of Commons chairs debates and keeps order; they must remain politically
impartial
The House of Lords
The House of Lords is the second chamber of Parliament. Unlike the Commons, its members are not elected. The
Lords has over 800 members, including:
- Life Peers: Appointed for their lifetime based on achievement in various fields
(business, science, arts, public service, etc.). They cannot pass their title to their children.
- Hereditary Peers: A small number who inherited their titles. Most hereditary peers lost
their automatic right to sit in the Lords in 1999, but 92 elected hereditary peers remain.
- Bishops: 26 senior bishops of the Church of England (known as "Lords Spiritual").
Role of the House of Lords:
- Reviews and suggests amendments to bills proposed by the Commons
- Scrutinizes government policy and administration
- Debates important issues
- Cannot block laws approved by the Commons for more than one year
- Cannot block or amend "money bills" (laws about taxation or public spending)
The Lords acts as a "revising chamber," using its expertise to improve legislation, but it cannot ultimately
overrule the elected Commons.
How Laws Are Made
The process of making a law involves several stages:
- First Reading: The bill is introduced; its title is read out, but there's no debate.
- Second Reading: The main principles of the bill are debated and voted on.
- Committee Stage: A small group of MPs examines the bill in detail, suggesting
amendments.
- Report Stage: The amended bill is reported back to the whole House for further
amendments.
- Third Reading: Final debate and vote on the bill.
- The Other House: The bill goes through similar stages in the other house (if it started
in the Commons, it goes to the Lords, and vice versa).
- Consideration of Amendments: If the second house makes changes, these must be agreed
upon by both houses.
- Royal Assent: Once both houses agree, the monarch gives formal approval, and the bill
becomes an Act of Parliament (law).
Important: Most bills (proposed laws) are introduced by the government, but individual MPs
can also propose laws called "Private Members' Bills." However, these rarely become law without government
support.
The Government
The government runs the country day-to-day and proposes new laws. It's formed by the political party (or
coalition of parties) that can command a majority in the House of Commons.
The Prime Minister
The Prime Minister (PM) is the head of government and the most powerful political figure in the UK. The PM is
the leader of the political party with the most seats in the Commons.
The Prime Minister's responsibilities include:
- Choosing members of the Cabinet
- Leading the government and setting its policy direction
- Representing the UK in international affairs
- Answering to Parliament
- Advising the monarch
The Prime Minister lives and works at 10 Downing Street in London, one of the most famous addresses in the
world.
The Cabinet
The Cabinet consists of about 20 senior government ministers chosen by the Prime Minister. Cabinet members
head major government departments (called "ministries" or "departments") such as:
- Chancellor of the Exchequer (responsible for the economy and financial matters)
- Home Secretary (responsible for immigration, policing, and security)
- Foreign Secretary (responsible for foreign affairs and relations with other countries)
- Education Secretary, Health Secretary, Defence Secretary, etc.
The Cabinet meets regularly to make important decisions about government policy. Traditionally, Cabinet
discussions are confidential, and all members must publicly support decisions once made (this is called
"collective responsibility").
The Civil Service
The civil service consists of politically neutral government employees who implement government policy. Civil
servants must serve whatever party is in power and cannot be politically active. The most senior civil
servant in each department is the Permanent Secretary.
The Opposition
The second-largest party in the House of Commons forms "Her Majesty's Most Loyal Opposition" (or "His
Majesty's" under a king). The Opposition has an important role in scrutinizing the government, proposing
alternatives, and holding ministers accountable.
The leader of the Opposition appoints a "Shadow Cabinet" that mirrors the real Cabinet, with each shadow
minister specializing in critiquing their government counterpart.
Devolution
Devolution means that certain powers have been transferred from the UK Parliament in Westminster to
assemblies in Scotland, Wales, and Northern Ireland. This allows these nations to make their own decisions
on certain matters while remaining part of the UK.
Scotland
The Scottish Parliament was established in 1999 in Edinburgh. It has 129 Members of the Scottish Parliament
(MSPs) elected every five years. The Scottish Government is led by the First Minister.
Powers devolved to Scotland include:
- Education
- Health
- Law and order (Scotland has its own legal system, which predates devolution)
- Environment and agriculture
- Many aspects of transport
- Some taxation powers
Powers reserved to Westminster: Foreign affairs, defense, immigration, and overall economic
policy remain under UK Parliament control.
Wales
The Welsh Parliament (Senedd Cymru) was established in 1999 in Cardiff. It has 60 Members of the Senedd (MS)
elected every five years. The Welsh Government is led by the First Minister.
Wales has powers over education, health, economic development, and local government. The Welsh language has
official status in Wales alongside English.
Northern Ireland
The Northern Ireland Assembly was established in 1998 as part of the Good Friday Agreement (Belfast
Agreement), which helped bring peace after decades of conflict known as "the Troubles."
The Assembly has 90 Members (MLAs) and meets at Stormont in Belfast. Due to Northern Ireland's history, the
government must be formed as a power-sharing executive, with positions divided between unionist and
nationalist parties.
Northern Ireland has its own legal and education systems, different from the rest of the UK. The Assembly has
been suspended several times due to political disagreements.
Remember: While Scotland, Wales, and Northern Ireland have their own
parliaments/assemblies, they remain part of the United Kingdom. Their MPs still sit in the UK Parliament at
Westminster and vote on UK-wide matters.
Elections and Voting
Who Can Vote?
To vote in UK elections, you must:
- Be 18 or over on election day (you can register to vote when you're 16)
- Be a British citizen, qualifying Commonwealth citizen, or citizen of the Republic of Ireland
- Be registered to vote
- Not be legally excluded from voting (e.g., members of the House of Lords cannot vote in general
elections, and prisoners serving sentences cannot vote)
Types of Elections
General Elections: Elect MPs to the House of Commons. Must be held at least every five
years. The Prime Minister can ask the monarch to dissolve Parliament and call an early election, though this
now requires a vote in the Commons.
Local Elections: Elect councillors to local government (councils). These are usually held in
May.
Elections to Devolved Parliaments/Assemblies: Scotland, Wales, and Northern Ireland hold
their own elections every five years.
The Electoral System
UK general elections use the "first past the post" system. The UK is divided into 650 constituencies, and
voters choose one MP for their constituency. The candidate with the most votes wins, even if they don't have
an absolute majority. This system usually produces a single party with a majority in Parliament, leading to
stable government, but critics say it's unfair to smaller parties.
Scottish Parliament, Welsh Parliament, and London Assembly elections use different systems involving
proportional representation.
Political Parties
Major UK political parties include:
- Conservative Party: Center-right; traditionally supports free markets, low taxation,
and strong defense.
- Labour Party: Center-left; traditionally supports workers' rights, public services, and
social equality.
- Liberal Democrats: Centrist; supports civil liberties and electoral reform.
- Scottish National Party (SNP): Supports Scottish independence.
- Green Party: Focuses on environmental issues.
- Various Northern Ireland parties: Including the Democratic Unionist Party (DUP) and
Sinn Féin.
The Legal System
The UK actually has three separate legal systems: one for England and Wales, one for Scotland, and one for
Northern Ireland. They have significant differences, though all are ultimately subject to UK Parliament.
The Courts
Different courts handle different types of cases:
- Magistrates' Courts: Handle minor criminal cases in England and Wales
- Crown Courts: Handle serious criminal cases with a jury
- County Courts: Handle civil disputes (disagreements between individuals or
organizations)
- High Court: Handles more complex civil cases
- Court of Appeal: Hears appeals from lower courts
- Supreme Court: The highest court in the UK (established in 2009), handling appeals on
the most important cases
The Jury System
In Crown Courts, cases are heard by a jury of 12 ordinary citizens (randomly selected from the electoral
register) who decide whether the accused is guilty or not guilty. The judge manages the trial and determines
sentencing if there's a conviction. Serving on a jury is a civic duty - if called, you must attend unless
you have a valid reason for exemption.
The Police
The police maintain law and order. The UK has a tradition of "policing by consent" - police have authority
because the public gives it to them, not through force. Most British police officers don't routinely carry
guns (though specialist armed units exist).
Important Rights: Everyone in the UK, including visitors, is innocent until proven guilty
in a court of law. You have the right to a fair trial, the right to legal representation, and protection
against discrimination.
Local Government
Local authorities (councils) provide many essential services in their area:
- Education (schools)
- Social services (help for children, elderly, and vulnerable people)
- Rubbish collection and recycling
- Roads and transport
- Libraries
- Planning permission for buildings and developments
- Parks and leisure facilities
Local councils are funded partly by "council tax" (a local property tax paid by residents) and partly by
grants from central government. Councillors are elected by local residents every four years in most areas.
Rights and Responsibilities of Citizens
Fundamental Rights
As a UK citizen or resident, you have many rights protected by law:
- Freedom of speech and expression (within the law - you can't incite violence or hatred)
- Freedom of religion and belief
- Freedom of assembly (the right to hold peaceful protests and demonstrations)
- Right to a fair trial
- Right to privacy
- Right to education
- Right to vote (if you're a British, Commonwealth, or Irish citizen)
- Protection from discrimination based on race, religion, gender, disability, age, or sexual orientation
The Human Rights Act 1998 incorporated the European Convention on Human Rights into UK law, providing
additional protections.
Responsibilities
Along with rights come responsibilities:
- Obey the law
- Pay taxes (income tax, council tax, etc.)
- Serve on a jury if called
- Help others and contribute to your community
- Respect others' rights and treat people with fairness
- Protect the environment
Test Success Tip: Government and democracy questions are common on the test. Make sure you
understand: the difference between the House of Commons and House of Lords, the role of the Prime Minister,
how laws are made, who can vote, and what devolution means. Remember that the UK has an unwritten
constitution and that Parliament is supreme.
