CBI today questioned former Telecom Minister A Raja for the second consecutive day in connection with the 2G spectrum allocation scam. AIR correspondent quoting official sources reports that Mr. Raja was confronted with some documents recovered by the agency during its raids on Department of Telecom offices in October last year after registering a case against unknown officers of DoT and telecom companies. CBI also quizzed him on the tapped conversation he had with corporate lobbyist Nira Radia about allegedly favouring certain telecom companies. CBI had earlier questioned the Nira Radia and former TRAI Chief Pradip Baijal in this connection. The agency sleuths raided over 30 places in Delhi and Tamil Nadu on the 15th of this month and questioned several people informally. The Supreme Court is closely monitoring the multi agency probe into the allocation of 2G spectrum to certain telecom firms. The apex court has asked CBI and Enforcement Department to submit status reports on their probe by February 10, when the 2G spectrum case will come up for hearing. The Comptroller and Auditor General of India in his report tabled in the Parliament had said that the undervalued spectrum allocation resulted in a huge loss to the exchequer. In a related development, a former associate of Nira Radia has alleged that senior BJP leaders L K Advani, Nitin Gadkari and Ananth Kumar have favoured the corporate lobbyist. Mr. Gadkari has dismissed the allegations saying this is cent per cent lie. Mr. Gadkari said he has not even seen Radia face-to-face.
