In March 1981, in a seven-page affidavit, Manickam alleged that his relatives had paid Rs. 10.75 lakh to the relatives of M. G. Ramachandran, chief minister of Tamil Nadu, as bribe for liquor distribution license, but they did not get the license. So, Manickam demanded the money back. This became a political sensation of the time, being used for political purposes by the opposition parties, DMK and the Congress, and resulted into three inquiry commissions.^[14][15][16]
