Westminster System - Operation

Operation

The pattern of executive functions within a Westminster System is quite complex. In essence, the head of state, usually a monarch or president, is a ceremonial figurehead who is the theoretical, nominal or de jure source of executive power within the system. In practice, such a figure does not actively exercise executive powers, even though executive authority may be exercised in his/her name.

The head of government, usually called the prime minister or premier, will ideally have the support of a majority in the responsible house, and must in any case be able to ensure the existence of no absolute majority against the government. If the parliament passes a resolution of no confidence, or refuses to pass an important bill such as the budget, then the government must either resign so that a different government can be appointed or seek a parliamentary dissolution so that new general elections may be held in order to re-confirm or deny the government's mandate.

Executive authority within a Westminster System is essentially exercised by the Cabinet, along with more junior ministers, although the head of government usually has the dominant role within the ministry. In the United Kingdom, the sovereign theoretically holds executive authority, even though the Prime Minister of the United Kingdom and the Cabinet effectively implement executive powers. In a parliamentary republic like India, the President is the de jure executive, even though executive powers are essentially instituted by the Prime Minister of India and the Council of Ministers.

As an example, the Prime Minister and Cabinet (as the de facto executive body in the system) generally must seek the permission of the head of state when carrying out executive functions. If, for instance the British Prime Minister wished to dissolve parliament in order for a general election to take place, the Prime Minister is constitutionally bound to request permission from the sovereign in order to attain such a wish. This power (along with others such as appointing ministers in the government, appointing diplomats, declaring war, and signing treaties, for example) are known as the Royal Prerogative, which in modern times are exercised by the sovereign solely on the advice of the Prime Minister. Since the British sovereign is a constitutional monarch, he or she abides by the advice of his or her ministers, except when executing reserve powers in times of crisis.

This custom also occurs in other Westminster Systems in the world, in consequence from the influence of British colonial rule. In Commonwealth Realms such as Canada, Australia or New Zealand, the Prime Minister is obligated to seek permission from the Governor-General when implementing executive decisions, in a manner similar to the British practice. An analogous scenario also exists in Commonwealth Republics, such as India or Trinidad and Tobago, where there is a President.

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 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 (reigned 1714 to 1727) was the first British monarch to delegate some executive powers to a Prime Minister and a cabinet of the ministers, largely because he was also the monarch of Hanover in Germany and did not speak English fluently. Over time, arrangement continued to exercise executive authority on the sovereign's behalf. Such a concept was reinforced in The English Constitution (1876) by Walter Bagehot, who emphasised the "dignified" and "efficient" aspects of government. In this sense Bagehot was stating that the sovereign should be a focal point for the nation, while the PM and cabinet actually undertook executive decisions.
