The Supreme Court has directed the CBI to go ahead with the probe into the 2G spectrum scam without being influenced by anybody's statement. Earlier, the Communication and IT Minister, Mr. Kapil Sibal had described as utterly erroneous the estimated loss of 1.76 lakh crore rupees to the exchequer on account of allocation of 2G spectrum to telecom operators. The Apex Court said Sibal's statement undermining the CAG report on the scam was unfortunate. The CAG had estimated a loss of upto 1.76 lakh crore rupees to the exchequer in allocation of 2G spectrum during the tenure of former Telecom Minister A Raja but Mr. Sibal had said that there was no loss at all. Meanwhile, Chairman Public Accounts Committee Dr Murli Manohar Joshi has requested the Lok Sabha Speaker Mrs. Meera Kumar to ensure that the authority of PAC and CAG is not impinged upon by ministers. Referring Kapil Sibal's statement about CAG report, Dr.Joshi said the Telecom Ministry was given ample time to give response CAG's findings. He questioned the timing of the statement when the report has already been tabled in parliament. In his letter Dr. Joshi said the Speaker should ensure that no such impropriety recurs.
