The Planning Commission of India, established in 1950, has been replaced by the new National Institution for Transforming India (NITI Aayog). NITI Aayog will serve as a think tank and advisory body to the government, unlike the Planning Commission which formulated five-year plans and allocated resources. The new body includes leaders from India's 29 states and 7 union territories and will have a CEO and experts who report directly to Prime Minister Narendra Modi as chairman. Critics argue this marks a power shift from the Planning Commission model to greater state involvement in a cooperative federalism approach.
