On 1 November 1956, under States Reorganisation Act, 1956, Delhi was converted from a state to a Union Territory. This resulted in the dissolution of the Delhi Legislative Assembly. In September 1966, with the passing of The Delhi Administration Act, 1966, the Delhi Metropolitan Council came into being, with 56 elected and five nominated members with the Lt. Governor of Delhi as its head. The Council however had no legislative powers, only an advisory role in the governance of Delhi. This set up functioned until 1990.
