New Delhi: Ratan Tata and Nira Radia were on Monday quizzed in connection with the 2G spectrum scam by Public Accounts Committee (PAC) whose chief Murli Manohar Joshi said the panel found the industrialist candid and the corporate lobbyist "evasive" in their responses.

Several revelations were made by Ratan Tata and Nira Radia before the Parliament panel in the three-hour-long questioning session. Tata accepted that he wanted A Raja for the post of Telecom Minister as he was facing problems from the then Telecom Minister, Dayanidhi Maran.

Tata also agreed that he had sent a letter regarding appointment of Raja to DMK patriarch M Karunandhi with the help of lobbyist Nira Radia. However, he declined to comment on being asked whether he wrote a letter to the former Prime Minister, Atal Bihari Vajpayee, in 2001.

He also accepted that he gave Rs 1600 crore to Unitech Wireless which he received later with interest. Tata also accepted that the voice recorded in the tape with Nira Radia was his own.

Initially, Nira Radia tried to divert the topic but later she succumbed to pressure when the panel threatened her of reprimanding and contempt of court. She also accused the agencies by saying that the tapes were doctored but accepted that in some tapes it was her voice.

The PAC chief said that industrialists Anil Ambani, Atul Jham (Atilasat), S Virk (Unitech, Managing Director), Amit Das (S Tel, CEO) will be questioned on April 5. Joshi, however, expressed happiness over the presentation made by Ratan Tata.

"I must say Ratan Tata was very candid. He answered clearly and very openly. He informed the committee that he was apprehensive of facing it, but his was a professional discussion," Joshi added.
