1. Weak:

A federal govern­ment is less effective in the spheres of foreign policy and national de­fence as compared to a unitary government. The component units may place impediments in the way of the central government in carry­ing out its treaty obligations with other states.

It is inefficient as compared to a unitary government because of diversity of law and administration obtaining in the country.

2. Clash between National and Local Interests:


There is always a tug-of-war going on be­tween local and national interests. Sometimes one is sacrificed for the sake of the other. This struggle is detrimental to the best interests of the country.

3. Highly Expensive:

A fed­eration is a highly expensive gov­ernment because there is duplica­tion of all political institutions.
