Zonal Councils are statutory bodies established under Part III of the States Reorganisation Act, 1956, for the purpose of promoting inter-state cooperation and coordination. There are five Zonal Councils in India: Northern, Central, Eastern, Western, and Southern. The Act specifies the composition of these councils. The Union Home Minister is designated as the Chairman of each of the five Zonal Councils. The Chief Ministers of the states included in each zone serve as members, and one of them is appointed as the Vice-Chairman for a period of one year on a rotational basis.
