BJP leader Murli Manohar Joshi, who is the Chairman of the Public Accounts Committee (PAC), has written to the Lok Sabha speaker Meira Kumar, stating that it was improper for Kapil Sibal to have criticized the 2G report prepared by the government's auditor. Mr Sibal, after being appointed Telecom Minister, had described the report of the Comptroller and Auditor General (CAG) as "erroneous".
