Mahatma Gandhi [SEP] Father of the Nation
Indians widely describe Gandhi as the father of the nation. Origin of this title is traced back to a radio address (on Singapore radio) on 6 July 1944 by Subhash Chandra Bose where Bose addressed Gandhi as "The Father of the Nation". On 28 April 1947, Sarojini Naidu during a conference also referred Gandhi as "Father of the Nation". However, in response to an RTI application in 2012, the Government of India stated that the Constitution of India did not permit any titles except ones acquired through education or military service.
