Solution:The zonal councils have been set up under the state reorganization Act, 1956 to advice on matters of common interest to each of the five zones into which the territory of India has been divided. Zonal councils are not constitutional bodies rather they are statutory bodies. Originally five zonal Councils were formed as per the States Reorganisation Act, 1956.They are-
Northern Zonal Council
Central Zonal Council
Eastern Zonal Council
Western Zonal Council
Southern Zonal Council
The North Eastern states i.e. (i) Assam (ii) Arunachal Pradesh (iii) Manipur (iv) Tripura (v) Mizoram (vi) Meghalaya and (vii) Nagaland are not included in the zonal council and their special problems are looked after by the North Eastern Council, setup under the North Eastern Council Act, 1971. Chandigarh, although not a state, is included in zonal council. Similarly, Delhi, Dadra & Nagar Haveli and Daman & Diu and Puducherry also have been included in the zonal councils.
