The British parliament discussed public use of the flag, and based on directives from England, the British Indian government threatened to withdraw funds from municipalities and local governments that did not prevent the display of the "Swaraj" flag. The "Swaraj" flag became the official flag of Congress at the 1931 meeting. However, by then, the flag had already become the symbol of the independence movement. A few days before India gained its independence in August 1947, the Constituent Assembly was formed. To select a flag for independent India, on 23 June 1947, the assembly set up an "ad hoc" committee headed by Rajendra Prasad and including Maulana Abul Kalam Azad, Sarojini Naidu, C. Rajagopalachari, K. M. Munshi and B. R. Ambedkar as its members. On 14 July 1947, the committee recommended that the flag of the Indian National Congress be adopted as the National Flag of India with suitable modifications, so as to make it acceptable to all parties and communities. It was also resolved that the flag should not have any communal undertones. The spinning wheel of the Congress flag was replaced by the "Chakra" (wheel) from the Lion Capital of Ashoka. According to Sarvepalli Radhakrishnan, the "chakra" was chosen as it was representative of "dharma" and law. However, Jawaharlal Nehru explained that the change was more practical in nature, as unlike the flag with the spinning wheel, this design would appear symmetrical. Gandhi was not very pleased by the change, but eventually came around to accepting it. The flag was proposed by Nehru at the Constituent Assembly on 22 July 1947 as a horizontal tricolour of deep saffron, white and dark green in equal proportions, with the Ashoka wheel in blue in the centre of the white band. 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. The design and manufacturing process for the national flag is regulated by three documents issued by the Bureau of Indian Standards (BIS). All of the flags are made out of khadi cloth of silk or cotton. The standards were created in 1968 and were updated in 2008.
