This detailed analysis explores the expert opinions on the Prime Minister and explains how executive power has developed in a parliamentary democracy. The views of constitutional experts and political scientists show that the Prime Minister is not simply one minister among many; the office carries an exceptional and unique authority. This topic is especially important for students preparing for competitive exams, because it explains why the Prime Minister often becomes the central face of the government and the main decision-making force within the Council of Ministers.
🎯 In this chapter, you will understand:
- Why political thinkers describe the Prime Minister as the most important leader in a parliamentary system.
- How the idea of the Prime Minister changed from primus inter pares to a powerful head of government.
- What famous scholars such as Lord Morley, Jennings, and H.J. Laski said about the Prime Minister’s authority.
- How the shift from cabinet government to Prime Ministerial government affects India and other Westminster-style democracies.
💡 Why this topic matters: The Prime Minister leads the government, guides the Council of Ministers, and often represents the country before Parliament and the public. Understanding expert opinions helps students see how much influence one constitutional office can hold in a democratic system.
🧠 Core Idea: In theory, a parliamentary government is run collectively by the Cabinet, but in practice the Prime Minister often becomes its central leader. Scholars use powerful images—such as a keystone, the sun, a captain, and a steersman—to explain this special position.
Expert Opinions on the Role and Authority of the Prime Minister
The role of the Prime Minister is often studied through the ideas of distinguished political philosophers and constitutional experts. In the story of modern governance, the observations made by eminent political scientists and constitutional experts about the Prime Minister’s role in Britain are not merely old historical notes. They remain highly relevant in the Indian parliamentary context because India also follows the broad Westminster framework of parliamentary democracy. Under this system, the executive is drawn from the legislature, remains responsible to it, and works through a Cabinet headed by the Prime Minister.
These expert views help us understand the “engine of the state” and the person who sits at its controls. A government may contain many ministers, departments, advisers, and officials, but the Prime Minister usually provides political direction, coordinates major decisions, and gives the administration a common purpose. For this reason, scholars have repeatedly tried to describe the Prime Minister’s real position through simple but powerful comparisons.
Views of Distinguished Thinkers and Political Philosophers
A variety of metaphors have been used by scholars to describe the immense importance of the Prime Ministerial office. These comparisons are useful because they turn a complex constitutional relationship into an easy picture. Some thinkers present the Prime Minister as the strongest member of a team; others describe the office as the centre around which the entire government moves.
- (i) Experts examine the relationship between the leader and the Cabinet.
- (ii) Their analysis focuses on the shift from collective responsibility to individual dominance.
- (iii) The Indian model mirrors many British observations because both systems share the Westminster framework.
Lord Morley and Herbert Morrison on Primus Inter Pares
The early understanding of the Prime Minister began with the Latin idea of primus inter pares, meaning first among equals. This phrase suggests that the Prime Minister is equal to other Cabinet ministers in formal status but stands first because of leadership, seniority, and political importance. Lord Morley famously described the Prime Minister as the ‘keystone of the cabinet arch’. Just as a keystone holds an arch together, the Prime Minister holds the Cabinet together; if that central stone is removed, the whole structure may weaken or fall.
Lord Morley also remarked that the head of the Cabinet occupies a position of exceptional and unique authority. This means that although the Prime Minister works with colleagues, the office carries a special weight that other ministers do not normally possess. Herbert Morrison accepted the technical phrase ‘primus inter pares’, but he argued that it was too modest a description of the influence actually exercised by the Prime Minister. In other words, calling the Prime Minister merely “first among equals” may hide the reality that the Prime Minister often guides, coordinates, and influences the work of the entire government.
- (i) Lord Morley emphasized the foundational necessity of the Prime Minister for Cabinet stability.
- (ii) Herbert Morrison argued that the phrase “first among equals” understates the Prime Minister’s actual influence.
Jennings and H.J. Laski on the Centrality of Power
As the office of Prime Minister evolved, scholars began using even stronger images. Jennings moved beyond the idea of “equals” and compared the Prime Minister to the sun around which all planets revolve. This comparison means that other ministers, departments, and political activities often move around the Prime Minister’s leadership. Jennings also described the Prime Minister as the keystone of the constitution and observed that “all roads in the constitution lead to the Prime Minister.” This shows that many important constitutional and political processes ultimately pass through the office of the Prime Minister.
H.J. Laski concentrated on the close relationship between the Prime Minister and the Cabinet. He said that the Prime Minister is “central to its formation, central to its life, and central to its death.” This means that the Prime Minister plays a major role when the government is formed, while it is functioning, and when it comes to an end. Laski therefore portrayed the Prime Minister as the pivot around which the entire governmental machinery revolves. A pivot is the central point on which something turns; in the same way, the Prime Minister often becomes the central point of government activity.
H.J. Laski’s Life and Death Cycle of the Cabinet
Laski’s statement can be understood in three simple stages. First, the Prime Minister is central to the formation of the Cabinet because the Prime Minister helps choose ministers and shapes the team that will run the government. Second, the Prime Minister is central to the Cabinet’s life because the Prime Minister coordinates policies, resolves differences, and provides leadership during day-to-day governance. Third, the Prime Minister is central to the Cabinet’s death because the resignation, removal, or death of the Prime Minister can lead to the end or major restructuring of the ministry.
- (i) H.J. Laski focused on the Prime Minister–Cabinet relationship.
- (ii) He portrayed the Prime Minister as the pivot of the entire governmental machinery.
Nautical Metaphors: Captains and Steersmen
The nautical perspective presents the Prime Minister as the main navigator of the nation’s journey. Scholars such as Munro and Ramsay Muir used maritime imagery to explain executive leadership. A ship needs many sailors and officers, but it also needs a captain or steersman to choose the direction and keep it steady during difficult conditions. Similarly, a government has many institutions and ministers, but the Prime Minister often provides the overall direction.
- (a) Munro: Described the Prime Minister as “the captain of the ship of the state”. This image highlights leadership, command, and responsibility for the overall direction of government.
- (b) Ramsay Muir: Portrayed the Prime Minister as “the steersman at the wheel of the ship of the state”. This image stresses guidance and control over the course of national policy.
- (c) Sir William Vernon Harcourt: Used celestial imagery and called the Prime Minister ‘inter stellas luna minores’, meaning a moon among lesser stars. The comparison suggests that the Prime Minister shines more brightly than other political figures.
- (d) H.R.G. Greaves: Noted that while the Government masters the country, the Prime Minister is the master of the Government. This means that the Prime Minister holds a leading position within the government itself.
The Emergence of Prime Ministerial Government
A major change in political science is the recognition that the British parliamentary system has gradually become more centralized. Earlier, the Cabinet was often seen as a team of ministers making decisions together under the principle of collective responsibility. Over time, however, many scholars observed that the Prime Minister became more dominant than the other members of the Cabinet. This development is commonly described as the movement from cabinet government to Prime Ministerial government.
In a cabinet system, ministers are expected to discuss policies, share responsibility, and present a united position before Parliament. But when the Prime Minister becomes exceptionally powerful, the Prime Minister may set the main agenda, control important appointments, guide major policies, and become the main spokesperson of the government. This does not mean that the Cabinet disappears; rather, it means that the Prime Minister’s leadership becomes more visible and influential than the collective character of the Cabinet.

- The Prime Minister provides political leadership to the Council of Ministers and coordinates major government decisions.
R.H. Crossman and Humphrey Berkeley’s Critiques
According to R.H. Crossman, the period after the war marked the complete transformation of cabinet government into Prime Ministerial government. This view suggests that the collective nature of the Cabinet has been overshadowed by the super-ministerial powers of one individual. Crossman’s argument does not say that Cabinet government is unimportant; instead, it highlights that the Prime Minister has become the dominant force within the executive.
Humphrey Berkeley went further and argued that Parliament is no longer sovereign in practice. He suggested that parliamentary democracy at Westminster has effectively collapsed under the weight of executive dominance. His criticism points to a concern that a very strong Prime Minister and a disciplined party system may reduce the practical ability of Parliament to independently question and control the government. This analysis is often considered relevant to the Indian parliamentary setup as well, where the Prime Minister may act as the main face of the administration and the central coordinator of government policy.
- (i) Humphrey Berkeley argued that Parliament is no longer sovereign in practice.
- (ii) He suggested that parliamentary democracy at Westminster has effectively collapsed under executive dominance.
- (iii) This analysis applies equally well to the Indian parliamentary setup, where the Prime Minister often acts as the sole face of the administration.
Summary of the Prime Minister’s Constitutional Significance
The transition from a first among equals to a Prime Ministerial government shows the dynamic nature of parliamentary democracy. In the beginning, the Prime Minister was viewed mainly as the senior member of a collective Cabinet. Later, scholars began to describe the office as the central force that holds the government together and gives it direction. For students, understanding these expert opinions from Lord Morley, Jennings, and Laski is vital for mastering the nuances of executive authority.
These ideas remain a keystone of modern political science because they explain how leadership, Cabinet responsibility, and constitutional practice work together. They are also essential for understanding the Indian constitutional reality, where the Prime Minister heads the Council of Ministers and plays a leading role in the functioning of the Union executive.
- The Prime Minister is the head of the Council of Ministers and the central leader of the government.
Key Features of Prime Ministerial Government
Prime Ministerial government does not remove the Cabinet, but it gives the Prime Minister a special position within it. The Prime Minister may influence the selection of ministers, guide the government’s agenda, coordinate important policies, and become the main representative of the administration. This is why scholars often use strong images to describe the office.
- Leadership: The Prime Minister provides direction to the Cabinet and the government.
- Coordination: The Prime Minister helps different ministers and departments work together.
- Central authority: The Prime Minister often becomes the main political face of the administration.
- Constitutional importance: The Prime Minister’s position is central to the working of a parliamentary executive.
