Former Telecom minister A Raja is likely to be questioned by the CBI in Delhi in the next couple of days in connection with the 2G spectrum allocation scam. Talking to reporters at Chennai state guest house before leaving for Delhi, Raja said, he will be in the capital for two-threedays and will cooperate with the investigating agency. The former telecom minister, who was on Monday issued summons along with corporate lobbyist Niira Radia to appear before the agency, said he has informed CBI that he will be in the national capital for two-three days. Raja had yesterday said that he was waiting for the dates from the CBI fopr appearing before it. The Supreme Court has asked CBI and the Enforcement Directorate to submit status reports on their investigations into the 2G scam to it by February 10, when the 2G spectrum case will come up for hearing. The Comptroller and Auditor General of India (CAG) in its report to Parliament had said that the allocation of 2G spectrum at undervalued prices had resulted in the loss of 1.76 lakh crore rupees to the exchequer. 47-year-old Raja was forced to resign as Telecom minister in the wake of the government auditor's report. Radia was questioned by the CBI yesterday at her South Delhi farmhouse for four hours. Radia hit the spotlight after her taped telephonic conversations with various influential people including industrialists, politicians and journalists became public. Supreme Court is closely monitoring the multi-agency probe in the allocation of 2G spectrum to certain telecom firms.
