The Rajamannar Committee was set up in 1969 by the Tamil Nadu government to secure the utmost autonomy for the states. The committee submitted its report in 1971. The important recommendations of the committee are as follows:

• Planning Commission should be disbanded and its place taken by a statutory body;

• Articles 356, 357, and 365 (dealing with President’s Rule) should be totally omitted; 

• The provision that the state ministry holds office at the pleasure of the governor should be omitted,etc.

The Sarkaria Commission was set up in 1983. It submitted its report in 1988.  The Commission made 247 recommendations to improve centre-state relations, which are
