Former Telecom Minister Arun Shourie will appear before the CBI next week in connection with the agency's probe into possible criminal aspects in the telecom policy since 2001. The CBI approached Shourie last week asking him to appear before the agency in connection with the Preliminary Enquiry registered by the agency following a direction from the Supreme Court.Officials said in New Delhi that the Enquiry is registered against unknown persons with an aim to ascertaining as to whether the first-come-first-serve basis provision passed by the then Cabinet led by Atal Bihari Vajpayee was followed or not. The CBI is likely to go into the minutes of the meetings held by successive Telecom Ministers which included late Pramod Mahajan, Shourie and Dayanidhi Maran. According to the CBI, nearly 50 licences were given out on the first-come-first-serve basis and Bharti, Vodafone and Idea are among the beneficiaries of the policy. The Supreme Court had on December 16 last year directed the agency to widen its investigation to cover the grant of licences by both the NDA and the UPA regimes between 2001-2007 and submit a report. Meanwhile, CBI is continuously grilling former telecom Minister A Raja and Shahid Balwa, DB Realty managing director and promoter of Swan Telecom Limited in connection with 2G Scam. Both of them who are in CBI custody till Monday were questioned together on licences allotted to the companies by showing favours. Our correspondent quoting CBI sources reports the agency has got some specific leads in the case.
