New row over 2G report: Has the national auditor's (CAG) office been discredited?

There is a massive row over the Comptroller and Auditor General's 2G report after a former auditor spoke to the media saying he had been forced to sign the report, even though he didn't agree with its findings. The official, RP Singh, has also accused BJP leader Murli Manohar Joshi, the head of Parliament's Public Accounts Committee, of unethical behaviour by getting in touch with the CAG while he was in the process of preparing the PAC report on 2G. The BJP has called this a Congress conspiracy and questioned the timing of RP Singh's allegations.
