Comptroller and Auditor General Vinod Rai has deposed before the Public Accounts Committee, PAC in connection with 2G spectrum allocation probe. The PAC, headed by BJP veteran Murli Manohar Joshi, is examining the controversial allocation of 2G radio waves. The CAG report, which presumed loss of 1.76 lakh crore rupees in 2G spectrum allocations, has proved to be quite an ammunition for the Opposition including the BJP and Left parties to target the government. A decision to ask Mr Rai to appear before the powerful parliamentary committee was taken during its last meeting earlier this month. The Committee has already invited views and suggestions on the 2G spectrum allocation. The PAC has already obtained some valuable information from the DoT, Finance Ministry, Telecom Regulatory Authority of India -TRAI and experts in the telecom sector through oral deposition and written submission.
