Single executive form:
When the right of taking the final decision on some issues of the executive is vested in an individual, it in called single executive. In Presidential executive, the focal point of administration is the President. For example, in the USA, all the powers of the federal government are vested in President.
So, the President is the single executive. In Parliamentary form of administration, as in England and India, the powers of the executive are in hands of the council of ministers, which is formed of many individuals, but because of the principles of collective responsibility, the council of ministers acts as one unit, so this form of executive also falls in the category of single executive.
Collective executive:
Where the powers of the executive remains in the hands of more than one person, it is called collective executive. For example, in Switzerland, the powers of the executive is in the hands of a federal committee consisting of 7 members. The senior – most member of the committee acts as a collective executive.
