He also said that it was Singh who had made a PowerPoint presentation before PAC on CAG's report on 2G issue. "He never raised the issue then," Joshi said.
He was asked to react on the statement of Gandhi that BJP stood exposed by the revelations made by Singh. Joshi is the chairman of PAC.
"Yes, certainly I think so," said Gandhi when reporters here asked whether BJP had been 'exposed' by Singh's comments.
Giving a twist to the 2G allocation row, Singh said a report prepared by him contained no losses on account of 2G spectrum allocation and questioned CAG's estimates of presumptive loss of Rs. 1.76 lakh crore.
"After completing the audit of Ministry of Telecom, which was under my direct charge, I prepared a draft audit report covering each and every aspect... My report did not contain any loss figure," he had said on Friday.
Responding to the charges, Joshi said, "Singh's allegations on 2G report are an attempt to malign CAG and PAC by vested interests including the government."
