Accused in the 2G spectrum case and former telecom minister A Raja on Monday began the cross-examination of key witness and former official AK Srivastava in a special court in New Delhi.
Raja's counsel and senior advocate Sushil Kumar asked former department of telecommunications (DoT) official Srivastava various question related to his work and the spectrum allocation during his tenure.
Testifying as a Central Bureau of Investigation (CBI) witness in the case, Srivastava earlier told the court about the investigation conducted by the probe agency in DoT.
According to the government auditor, Raja was biased while distributing second generation (2G) mobile airwaves and operating licences to telecom firms, causing a loss of up to Rs. 1.76 lakh crore in revenue to the treasury.
