πŸ›οΈ Parliament Basics

πŸ’‘ What is Parliament?

Parliament is the UK's supreme law-making body. It consists of the House of Commons, House of Lords, and the Crown (represented by the monarch). Together, they create laws, scrutinize government, and represent the people's interests.

Parliament's Three Main Functions

  • Making Laws: Creating, amending, and repealing legislation that governs the UK
  • Scrutinizing Government: Holding ministers accountable for their actions and policies
  • Representing Citizens: Voicing the concerns and interests of constituents across the UK

Key Principles

Parliamentary Sovereignty

Parliament has the ultimate legal authority in the UK. It can make or unmake any law, and no person or body can override or set aside Parliament's legislation.

Democratic Accountability

MPs are directly elected by the people and must answer to their constituents. The government must maintain the confidence of Parliament to remain in power.

Separation of Powers

While Parliament makes laws, the judiciary interprets them, and the executive (government) implements them. This separation prevents any one branch from having too much power.

πŸ—οΈ Parliament Structure

The Three Parts of Parliament

House of Commons

  • 650 elected Members of Parliament (MPs)
  • Directly elected by voters
  • 5-year maximum terms
  • Primary legislative chamber
  • Controls government finances
  • Can bring down governments

House of Lords

  • Around 800 unelected members
  • Life peers, hereditary peers, bishops
  • Appointed for life
  • Revising chamber
  • Scrutinizes legislation
  • Cannot block most government business

πŸ‘‘ The Crown

The monarch is the third component of Parliament. In practice, the Crown's role is ceremonial:

  • Royal Assent: All bills must receive Royal Assent to become law (now automatic)
  • State Opening: The monarch opens each Parliamentary session
  • Dissolution: Parliament is dissolved in the Crown's name before elections
  • Formalities: Various ceremonial functions throughout the Parliamentary year

Physical Layout

"The physical layout of Parliament isn't just historicβ€”it shapes how politics works. The adversarial seating in the Commons, with government and opposition facing each other, reflects the combative nature of British politics."

Composition and Elections

650 Constituencies

The UK is divided into 650 constituencies, each electing one MP:

  • England: 543 constituencies
  • Scotland: 59 constituencies
  • Wales: 40 constituencies
  • Northern Ireland: 18 constituencies

First Past the Post

MPs are elected using the First Past the Post system:

  • The candidate with the most votes wins
  • No need for an absolute majority (50%+)
  • Winner takes all - other votes don't count
  • Can produce results where vote share doesn't match seat share

Key Roles in the Commons

The Speaker

  • Neutral Chair: Maintains order during debates and votes
  • Procedural Authority: Interprets rules and decides on parliamentary procedure
  • MPs' Champion: Protects parliamentary rights and privileges
  • Elected Position: Chosen by MPs, traditionally serves until retirement

Government Front Bench

  • Prime Minister: Head of government, leads the executive
  • Cabinet Ministers: Heads of government departments
  • Junior Ministers: Support cabinet ministers in their departments
  • Parliamentary Private Secretaries: Links between ministers and backbenchers

Opposition Front Bench

  • Leader of the Opposition: Heads the largest non-government party
  • Shadow Cabinet: Opposition spokespeople for different policy areas
  • Shadow Ministers: Track and critique specific government departments
  • Opposition Whips: Organize opposition MPs and coordinate tactics

πŸ‘‘ House of Lords

Composition

Life Peers (~700)

Appointed by the monarch on advice of the Prime Minister:

  • Experts in various fields
  • Former politicians
  • Distinguished public servants
  • Serve until death

Hereditary Peers (~90)

Inherited titles, severely limited since 1999:

  • 92 hereditary peers allowed to sit
  • Elected by other hereditary peers
  • Replaced when they die or retire
  • Controversial anachronism

Lords Spiritual (~26)

Senior bishops of the Church of England:

  • Archbishops of Canterbury and York
  • Bishop of London
  • 21 other senior bishops
  • Automatic seats by virtue of church position

Powers and Limitations

What Lords Can Do

  • Scrutinize and amend legislation
  • Delay bills for up to one year
  • Hold government accountable through questions
  • Conduct detailed committee investigations
  • Initiate their own legislation

What Lords Cannot Do

  • Permanently block Commons legislation
  • Amend or delay financial bills
  • Vote on matters of confidence
  • Force a general election
  • Ignore the "Salisbury Convention"

The Salisbury Convention

πŸ“œ Constitutional Convention

The Lords will not oppose legislation that was in the government's election manifesto. This ensures that the elected government can implement its promised policies, even though the Lords is unelected.

πŸ‘₯ MP Roles & Responsibilities

What MPs Actually Do

πŸ›οΈ Parliamentary Work

  • Voting: Supporting or opposing legislation and government motions

Types of MPs

Government Ministers

MPs who also serve in the executive branch:

Party Whips

"Whips are the enforcers of party discipline. They ensure MPs vote the party line and maintain party unity. The 'whip' system can sometimes conflict with MPs' independent judgment or constituency interests."
Parliamentary Practice Analysis

The Whipping System:

  • One-line whip: Information only, no pressure to attend
  • Two-line whip: Expected to attend and vote with party
  • Three-line whip: Must attend, serious consequences for rebellion
  • Free vote: MPs can vote according to conscience

βš–οΈ How Laws Are Made

The Legislative Process

πŸ“‹ From Idea to Law

Turning an idea into law is a complex process involving multiple stages of scrutiny, debate, and approval. Understanding this process helps you see where citizen input can be most effective.

Types of Bills

Government Bills

Introduced by government ministers:

  • Most likely to become law
  • Have government support and time
  • Usually based on manifesto commitments
  • Drafted by civil servants

Private Members' Bills

Introduced by individual MPs or Lords:

  • Limited parliamentary time
  • Often fail due to lack of time or government opposition
  • Can raise awareness of issues
  • Occasionally become law with government support

Private Bills

Affect specific organizations or areas:

  • Usually for local authorities or companies
  • Different procedure from public bills
  • Less common than other types
  • Often technical or administrative

The Bill's Journey

Stage 1: First Reading

  • Bill introduced and title read out
  • No debate or vote
  • Sets date for Second Reading
  • Bill published for public and MP scrutiny

Stage 2: Second Reading

  • Debate on general principles
  • Minister explains purpose and benefits
  • Opposition response and backbench contributions
  • Vote determines if bill proceeds

Stage 3: Committee Stage

  • Line-by-line examination
  • Amendments proposed and voted on
  • Expert evidence often taken
  • Can substantially change the bill

Stage 4: Report Stage

  • Further amendments considered
  • All MPs can participate
  • Chance to reverse committee decisions
  • Government often introduces own amendments

Stage 5: Third Reading

  • Final debate on amended bill
  • Usually brief
  • No major amendments allowed
  • Final Commons vote

Stage 6: House of Lords

  • Similar process in Lords
  • Can propose amendments
  • Back to Commons if amended
  • "Ping-pong" until agreement reached

Stage 7: Royal Assent

  • Formal approval by the Crown
  • Now automatic (last refusal in 1708)
  • Bill becomes an Act of Parliament
  • Law comes into effect
