NEW DELHI (TIP): The Congress on Thursday seized on the low yields of the 2G spectrum auction to attack the federal auditor’s Rs 1.76 lakh crore revenue loss projection, setting the stage for another round of bitter feuding with the opposition. After the Supreme Court-ordered 2G auction yielded just Rs 9,407 crore, information and broadcasting minister Manish Tewari hit out at the comptroller and auditor general, saying, “Mr CAG, where is the 1.76 lakh crore? I think it is time for some serious introspection.” He also attacked the main opposition BJP, saying, “It is high time the BJP and some of the other opposition parties, which had made this their holy grail and swansong of politics over the last two years, publicly apologize.”
