. However, uncodified conventions, practices, and precedents continue to play a significant role in most countries, as many constitutions do not specify important elements of procedure.

Sometimes these conventions, reserve powers, and other influences collide in times of crisis and in such times the weaknesses of the unwritten aspects of the Westminster system, as well as the strengths of the Westminster system's flexibility, are put to the test.

Executive authority within a Westminster system is de jure exercised by the cabinet as a whole, along with more junior ministers, however, in effect, the head of government dominates the executive as the head of government is ultimately the person from whom the

Thus the cabinet is strongly subordinate to the prime minister as they can be replaced at any time, or can be moved ("demoted") to a different portfolio in a cabinet reshuffle for "underperforming". In the United Kingdom, the sovereign theoretically holds executive authority, even though the

in order to attain such a wish. However, the sovereign, in modern times, has virtually always followed the advice of their prime minister without their own agency.

, where the respective prime ministers have the full legal power to implement executive decisions, and presidential (in Israel) or imperial (in Japan) approval is not required; the prime ministers of these nations are fully the ''de jure'' source of executive authority, and not the head of state. The head of state will often hold meetings with the head of government and cabinet, as a means of keeping abreast of governmental policy and as a means of advising, consulting and warning ministers in their actions. Such a practice takes place in the United Kingdom and India. In the UK, the sovereign holds confidential weekly meetings with the prime minister to discuss governmental policy and to offer his or her opinions and advice on issues of the day. In India, the prime minister is constitutionally bound to hold regular sessions with the president, in a similar manner to the aforementioned British practice. In essence, the head of state, as the theoretical executive authority, "reigns but does not rule". This phrase means that the head of state's role in government is generally ceremonial and as a result does not directly institute executive powers. The reserve powers of the head of state are sufficient to ensure compliance with some of their wishes. However, the extent of such powers varies from one country to another and is often a matter of controversy. Such an executive arrangement first emerged in the United Kingdom. Historically, the British sovereign held and directly exercised all executive authority.
George I of Great Britain George I (George Louis; ; 28 May 1660 – 11 June 1727) was King of Great Britain and King of Ireland, Ireland from 1 August 1714 and ruler of the Electorate of Hanover within the Holy Roman Empire from 23 January 1698 until his death in 1727. ...

Although the dissolution of the legislature and the call for new elections is formally performed by the head of state, the head of state, by convention, acts according to the wishes of the head of government. A president, monarch, or governor-general might possess clearly significant reserve powers. Examples of the use of such powers include the Australian constitutional crisis of 1975 and the Canadian King–Byng affair in 1926. The Lascelles Principles were an attempt to create a convention to cover similar situations, but have not been tested in practice. Because of differences in their written constitutions, the formal powers of monarchs, governors-general, and presidents vary greatly from one country to another. However, as sovereigns and governors-general are not elected, and some presidents may not be directly elected by the people, they are often shielded from any public disapproval stemming from unilateral or controversial use of their powers. In many

The English Constitution ''The English Constitution'' is a book by Walter Bagehot. First serialised in ''The Fortnightly Review'' between 15 May 1865 and 1 January 1867, and later published in book form in 1867, it explores the constitution of the United Kingdom—spec ...
'', Walter Bagehot emphasised the divide of the constitution into two components, the Dignified (that part which is symbolic) and the Efficient (the way things actually work and get done), and called the Efficient " Cabinet Government". Members of the Cabinet are collectively seen as responsible for government policy, a policy termed cabinet collective responsibility. All Cabinet decisions are made by consensus, a vote is rarely taken in a Cabinet meeting. All ministers, whether senior and in the Cabinet, or junior ministers, must support the policy of the government publicly regardless of any private reservations. When a Cabinet reshuffle is imminent, a lot of time is taken up in the conversations of politicians and in the news media, speculating on who will, or will not, be moved in and out of the Cabinet by the Prime Minister, because the appointment of ministers to the Cabinet, and threat of dismissal from the Cabinet, is the single most powerful constitutional power which a Prime Minister has in the political control of the Government in the Westminster system. The Official Opposition and other major political parties not in the Government, will mirror the governmental organisation with their own Shadow cabinet made up of Shadow Ministers.


Bicameral and unicameral parliaments

In a Westminster system, some members of parliament are elected by popular vote, while others are appointed. Nearly all Westminster-based parliaments have a

. Secretaries had remained to be chosen by the Chief Executive not from the Legislative Council, and their appointments need not be approved by the Legislative Council. Although essentially more presidential than parliamentary, the Legislative Council had inherited many elements of the Westminster system, including parliamentary powers, privileges and immunity, and the right to conduct inquiries, amongst others. Minutes are known as Hansards, and the theme colour of the meeting chamber is red as in other upper houses. Government secretaries and other officials are seated on the right hand side of the President in the chamber. The Chief Executive may dissolve the Legislative Council under certain conditions, and is obliged to resign, e.g., when a re-elected Legislative Council passes again a bill that he or she had refused to sign.

, which must be willing to pass all its legislation. Although government is formed in the lower house, the House of Representatives, the support of the Senate is necessary in order to govern. The Australian Senate is unusual in that it maintains an ability to withhold supply from the government of the day – a power similar to that held in the UK until 1911 by the House of Lords, which has since then been impossible, in the Westminster system. A government that has lost supply is severely restricted in its abilities to act; unless a solution can be negotiated and supply can be restored, such an occurrence would normally trigger a federal election. Since the

). This is controversial because it conflicts with the Westminster tradition of government by a party with the confidence of the lower house (not an upper house like the Senate). Some political scientists have held that the Australian system of government was consciously devised as a blend or hybrid of the Westminster and the United States systems of government, especially since the Australian Senate is a powerful upper house like the US Senate; this notion is expressed in the nickname "the Washminster mutation". The ability of upper houses to block supply also features in the parliaments of most Australian states. The Australian system has also been referred to as a semi-parliamentary system.


Ceremonies

The Westminster system has a very distinct appearance when functioning, with many British customs incorporated into day-to-day government function. A Westminster-style parliament is usually a long, rectangular room, with two rows of seats and desks on either side. Many chambers connect the opposing rows, either with a perpendicular row of seats and desks at the furthermost point from the Speaker's Chair at the opposite end of the chamber (e.g. UK House of Lords or Israel Knesset) or the rows of chairs and desks are rounded at the end, opposite to the Speaker's Chair (e.g. Australian chambers, Ireland, South Africa, India). The chairs in which both the government and opposition sit, are positioned so that the two rows are facing each other. This arrangement is said to have derived from an early Parliament which was held in a church

. Traditionally, the opposition parties will sit in one row of seats, and the government party will sit in the other. In some countries, the mace will face the government’s side whilst lying on the table of the House. In most majority governments, the number of government-party MPs is so large that it must use the "opposition" seats as well. In the lower house at Westminster (the UK's House of Commons) there are lines on the floor in front of the government and opposition benches that members may cross only when exiting the chamber. At one end of the room sits a large chair, for the Speaker of the House. The speaker usually wears black robes, and in some countries, a wig. Robed parliamentary

often sit at narrow tables between the two rows of seats, as well. These narrow tables in the centre of the chamber, is usually where ministers or members of the house come to speak. A newly elected Speaker is symbolically dragged to the Chair upon being elected. Other ceremonies sometimes associated with the Westminster system include an annual Speech from the Throne (or equivalent thereof) in which the head of state gives a special address (written by the government) to parliament about what kind of policies to expect in the coming year, and lengthy

ceremonies that often involve the presentation of a large ceremonial mace. Some legislatures retain Westminster's colour-coded chambers, with the upper houses associated with the colour red (after the House of Lords) and the lower with green (after the House of Commons). This is the case in India, Australia, Canada, New Zealand, and Barbados.


Current countries

Countries that use variations on the theme of the Westminster system, as of 2023, include the following:


Former countries

The Westminster system was adopted by a number of countries which subsequently evolved or reformed their system of government departing from the original model. In some cases, certain aspects of the Westminster system were retained or codified in their constitutions. For instance
