On the basis of relationship between the executive and the legislature, government may be classified as Parliamentary and Presidential.

As Leacock put it, “in a Parliamentary System, the tenure of office of the virtual executive is dependent on the will of the legislature; in Presidential government, the tenure of office of the Executive is independent of the will of the legislature.” Under Presidential system the Chief Executive Head who is invariably a President is both the head of the state and head of the Government.

Under Parliamentary System, the two are different. The Head of the state is either a President or a King or a Queen or a Governor General and Head of Government is the Prime Minister.

The head of the state in parliamentary system simply enjoys nominal powers and is just a figurehead or titular head whereas the real and effective powers are enjoyed by the Prime Minister and his cabinet. An elaborate distinction between the two is brought out as follows :

Parliamentary System

1. Intimacy between the Executive and the Legislature:

Under this system there is a close relationship between the Execu­tive and the legislature. The mem­bers of the Executive, i.e., the Prime Minister and his cabinet col­leagues are also the members of the legislature. They in fact enjoy the support of the majority in the legislature.


Thus the Prime Minis­ter and his cabinet can pass, amend or repeal any type of law with the support of subservient majority in the legislature. In this way, the executive and the legislative branches of the Government work in close harmony. The Executive not only runs the administration but also makes law.

2. Responsibility to the legislature:

In this system, the execu­tive is responsible and accountable to the legislature for all its acts of omission and commission. The legislature can remove a cabinet by passing a vote of no-confidence against it whenever it so desires.

Moreover, the legislature exer­cises its control over the executive through interpellation, adjourn­ment motions so on and so forth.

3. Gap between Practice and Theory:


In a Parliamentary System, there is always a gap be­tween law and fact. According to law, all powers of the Government are vested in the Chief Executive head who may be President as in India or Governor General as in Canada or King or Queen as in U.K. In actual fact all his powers are exercised by the Cabinet which is created out of the majority party in the legislature.

The Chief Ex­ecutive head is just an ornamental head or figure head. All real and effective authority is exercised by the Cabinet.

Presidential System

1. Separation between the Executive and the Legislature:

The executive and the legislative branches of the government under the system are separate and inde­pendent of each other. The Execu­tive which generally consists of a President and a cabinet subordi­nate to him runs the administration of the country. It has nothing to do with law-making.

The President or his ministers are neither the mem­bers of the legislature nor do they enjoy any support of a majority in it. Sometimes, the President may belong to one Party and another Party may have a majority in the legislature and both may run at cross purposes. The fact is clear from the working of this system in U.S.A.

2. Presidential Executive is not responsible to the Legisla­ture:


Under this system the Ex­ecutive is independent of the legis­lature and is not responsible to it. The President has a fixed tenure of office and cannot be removed by an adverse vote in the legislature.

The ministers are appointed and dismissed by the President himself and the Legislature cannot touch them. Since none of them is a member of the Legislature, they cannot be subjected to any parlia­mentary criticism.

3. No Gap between Practice and Theory:

Under this system, there is no such gap between law and fact. The Chief Executive head is the President in whom executive authority is vested by the constitution.

He controls effe­ctively his cabinet, which works under him and acts according to his wishes. This fact is clearly il­lustrated in the working of the Presidential System in the U.S.A.
