System Overview

Origin and Definition

The Westminster system, also known as the Westminster model, is a parliamentary system of government characterized by specific legislative procedures. It originated in England and is named after the Palace of Westminster, the seat of the Parliament of the United Kingdom. Its defining features include an executive branch composed of legislators, responsible to the legislature, the presence of parliamentary opposition, and a distinct ceremonial head of state separate from the head of government.

Global Diffusion

This model was widely adopted by former colonies of the British Empire upon achieving self-government, beginning with the Province of Canada in 1848 and several Australian colonies between 1855 and 1890. While some nations, like the United States and Cyprus, adopted different systems, many continue to utilize or have adapted the Westminster framework. Examples include Canada, Australia, New Zealand, India, and Israel, though some have since transitioned to presidential or hybrid models.

Contrasting Systems

The Westminster system is often contrasted with the presidential system, which originated in the United States, and the semi-presidential system, exemplified by France. Key distinctions lie in the relationship between the executive and legislative branches, the fusion or separation of powers, and the role of the head of state.

Core Characteristics

Head of State

A sovereign or head of state serves as the nominal or legal holder of executive power. This figure typically performs ceremonial duties and possesses reserve powers, but day-to-day executive functions are handled by the head of government. Examples include monarchs (like King Charles III) or presidents in many Commonwealth realms and republics.

Head of Government

The head of government, commonly known as a Prime Minister, Premier, or Chief Minister, is appointed by the head of state. Constitutional convention dictates that this individual must command the support of a majority of elected members of parliament. Typically, this is the leader of the largest political party or coalition in the legislature.

Executive and Cabinet

The executive branch is led by the head of government and usually comprises members of the legislature. Senior members form the Cabinet, which operates under the principle of cabinet collective responsibility. This means all ministers publicly support government policy, regardless of private reservations.

Civil Service and Opposition

An independent, non-partisan civil service supports the government by advising on and implementing policy. Simultaneously, a parliamentary opposition, often led by a Leader of the Opposition, plays a crucial adversarial role, scrutinizing government actions and presenting alternative policies.

Legislature and Confidence

Legislatures are often bicameral (with an upper and lower house) but can be unicameral. The lower house, representing the people, holds significant power, including the ability to dismiss the government by withholding supply or passing a motion of no confidence. Parliaments can also be dissolved, leading to snap elections.

System Operation

Executive Authority Dynamics

While the head of state is the theoretical source of executive power, actual authority resides with the head of government and the cabinet. The prime minister's influence is paramount; cabinet members serve at their pleasure, and reshuffling is a key tool of political control. The head of state typically acts on the advice of the prime minister, even for actions like dissolving parliament.

Consultation and Advice

Heads of state often meet with their heads of government to stay informed and offer counsel. In the UK, the sovereign holds weekly meetings with the prime minister. In India, the prime minister is constitutionally bound to regular sessions with the president. This consultative role allows the head of state to "reign but not rule," influencing policy through advice, though direct intervention is rare and often controversial.

Reserve Powers and Conventions

Reserve powers, though seldom used, can be significant. Historical examples like the 1975 Australian constitutional crisis highlight their potential impact. The Lascelles Principles offer guidance for such situations, but the unwritten nature of many Westminster conventions means their application can be subject to interpretation and debate, especially during political crises.

Typical Structure

Structural Components

The Westminster model typically features a bicameral legislature, though unicameral systems exist. The lower house is elected to represent the populace and initiate legislation, while the upper house often scrutinizes and approves laws. The head of state is usually a monarch or ceremonial president, with the head of government (Prime Minister) leading the executive, which is formed from and responsible to the legislature.

Type Bicameral (unicameral in some circumstances) Elected or appointed upper house to approve and/or scrutinise laws.
  • Senate, Legislative Council, House of Lords
Elected lower house to represent the people and (normally) initiate legislation.
  • House of Commons, House of Representatives, Legislative Assembly
Leadership Head of state Monarch (sometimes represented by a vice-regal representative, such as a governor or governor-general) or ceremonial president.
Head of government

Usually the leader of the largest party in the lower house (legislature if unicameral).

  • Prime minister in a sovereign state/country
  • Premier/chief minister in provinces, states, or territories.
  • Other titles include first minister, chief executive, president of the council of ministers.
Presiding officers of legislative chambers Speaker (or president) of the upper house
Speaker of the lower house
General Government

Formed by the largest party/coalition in the lower house (legislature if unicameral), and led by the head of government.

  • Executive ministers are chosen (normally) from members of the government party or coalition, by the head of government. They may be from either house in bicameral systems.
  • A Cabinet is formed from the most senior ministers, but may include some civil servants.
  • In parliaments without political parties, ministers are either chosen by the prime minister or elected by members at large.
  • Government sits in and is responsible to the legislature, to which it reports and is accountable (in particular, to the lower house, if bicameral).
Opposition Led by the leader of the opposition. A shadow cabinet is formed out of the elected members of the largest party or coalition in the legislature not in government, chosen by the party leader (the leader of the opposition).
Public service Politically independent and available to the people of the state, that will work for various government organisations (health, housing, education, defence).
Armed forces Defensive organisation of the state/country.

Electoral Systems & Officials

Electoral Framework

Electoral systems are often defined by legislation, such as Representation of the People Acts. While first-past-the-post is common, many Westminster systems utilize proportional representation or parallel voting. The composition of the legislature can vary, with some countries having fully elected upper houses (like Australia) or unicameral systems.

Ministerial Roles

Key officials include ministers, parliamentary secretaries, and under-secretaries. Government departments are managed by permanent secretaries or principal secretaries. The Speaker presides over legislative chambers, often with symbolic duties and the power to maintain order.

Legislative Powers

The lower house holds the power to dismiss the government through votes of no confidence or by blocking essential legislation like the budget. Parliamentary privilege protects legislators' speech and actions within the chamber, ensuring free debate.

Role of the Head of State

Ceremonial Functions

The head of state formally appoints the head of government, typically the individual who commands the confidence of the lower or sole legislative house. This appointment process, known as "kissing hands" in the UK, is largely symbolic. The head of state also formally dissolves parliament for elections, usually acting on the prime minister's advice.

Reserve Powers

While not actively governing, heads of state may possess significant reserve powers. These powers, though rarely exercised, can be crucial in constitutional crises. Their application is often guided by convention, such as the Lascelles Principles, and can be controversial, as seen in Australia's 1975 constitutional crisis.

Representation Abroad

In Commonwealth realms, governors-general represent the monarch, performing similar functions. In republics, presidents may serve a similar ceremonial role. The head of state's actions are often shielded from public scrutiny due to their non-elected status, providing a buffer during political turbulence.

Cabinet Government

Collective Responsibility

Cabinet government, as described by Walter Bagehot, is the "efficient" part of government. Cabinet ministers are collectively responsible for policy, making decisions by consensus. All members must publicly support government decisions, even if they privately disagree. This principle ensures government unity and stability.

Prime Ministerial Power

The Prime Minister holds significant constitutional power, primarily through the ability to appoint and dismiss cabinet ministers. Cabinet reshuffles are a potent tool for managing the government and asserting authority. The opposition often mirrors the government's structure with a "Shadow Cabinet" of its own senior members.

Legislative Structures

Bicameral vs. Unicameral

Most Westminster systems feature a bicameral parliament, with an elected lower house and an appointed or elected upper house. However, some countries, like New Zealand and several Canadian provinces, have unicameral legislatures. The powers and composition of upper houses vary significantly, with some, like the Australian Senate, wielding substantial influence.

"Washminster" Hybrid

Australia presents a unique "Washminster" hybrid, blending Westminster traditions with elements of the US presidential system. Its powerful, fully elected Senate can block legislation and withhold supply, a power largely lost by the UK's House of Lords. This structure allows the Senate to significantly influence governance, sometimes leading to constitutional crises.

Ceremonial Aspects

Westminster parliaments often incorporate elaborate ceremonies. The layout of chambers, with government and opposition benches facing each other, reflects historical church seating. Ceremonies like the State Opening of Parliament and the presentation of the mace, along with the Speaker's traditional attire, contribute to the system's distinct parliamentary culture.

Current Adoptions

Global Presence

The Westminster system, in various forms, is utilized across numerous countries. These include monarchies like the United Kingdom, Canada, Australia, and Japan, as well as republics such as India, Ireland, and Singapore. Many nations have adapted the model to suit their specific political and historical contexts, incorporating elements like proportional representation or modified executive powers.

Historical Adoptions

System Evolution

Several nations have transitioned away from the Westminster model or significantly reformed their systems. South Africa, for instance, moved from a Westminster system to a presidential one. Nigeria also shifted towards a presidential system after initial adoption. These changes reflect evolving political landscapes and attempts to address specific governance challenges.

Notable Departures

Countries like Rhodesia (now Zimbabwe) and Burma (now Myanmar) operated under Westminster-style governments before political upheavals led to different systems. Ceylon (now Sri Lanka) also transitioned to an executive presidential system. These historical shifts illustrate the adaptability and sometimes the limitations of the Westminster model in diverse contexts.

  • Union of South Africa (1910–1961), Republic of South Africa (1961–1984)
  • Dominion of Newfoundland (1907–1934)
  • Rhodesia (1965–1979)
