The national flag of India is a horizontal rectangular tricolour of Deep saffron, White and Dark green with the Ashok Chakra, a 24-spoke wheel, in navy blue at its centre. It was adopted in its present form during a meeting of the Constituent Assembly held on 22 July 1947, when it became the official flag of the Dominion of India. The flag was subsequently retained as that of the Republic of India. The flag was proposed by Nehru at the Constituent Assembly on 22 July 1947 as a horizontal tricolor of deep saffron, white and dark green in equal proportions, with the Ashoka wheel in blue in the centre of the white band. Jawaharlal Nehru also presented two flags, one in Khadi-silk and the other in Khadi-cotton, to the assembly. The resolution was approved unanimously. It served as the national flag of the Dominion of India between 15 August 1947 and 26 January 1950, and has served as the flag of the Republic of India since then.
