After the flop 2G spectrum auction that yielded only Rs.9,407 crore, Government and the Congress on Thursday (November 15) questioned the Comptroller and Auditor General's estimated loss of Rs.1.76 lakh crore in the spectrum allocation of 2001, drawing fire from the opposition. Information and Broadcasting minister Manish Tewari led the government attack by asking CAG Vinod Rai as to why the spectrum auction had not yielded anything close to the loss it had estimated.
