New Delhi/Mumbai (JPN/Bureau): The CBI probing 2G spectrum scam has asked former Telecom Minister Arun Shourie to appear before it on February 21. Shourie, who held the telecom portfolio between January 2003 and May 2004 in the NDA regime, has given consent for his appearance.

The agency will take his statement in connection with its probe into possible criminal aspects in the telecom policy since 2001.

The Central Bureau of Investigation approached Shourie last week asking him to appear before it in connection with the Preliminary Enquiry (PE) registered by the agency following a direction from the Supreme Court.

The PE was registered against "unknown persons" with an aim to ascertaining as to whether or not the "first-come-first-serve basis" provision passed by the then Cabinet led by Atal Bihari Vajpayee was followed, officials in New Delhi said.

Shourie said that he would be handing over some documents to the CBI during his appearance before the agency on February 21.

Earlier, Shourie had stated that he was aware of the scam and had even arranged meeting between CBI Director Ashwini Kumar and the person who had given him information related to it.

BJP spokesperson Ravi Shankar Prasad said the party had nothing to hide and is open for enquiry.

Prasad however said he differed with Shourie's comments that he had informed top BJP leaders like Arun Jaitley and Sushma Swaraj about the 2G scam in 2007 but they had kept quiet.

"We raised this issue in the Parliament and outside. What the BJP has done over this issue is for everybody to see. I disagree with Shourie's comments," he told reporters in Mumbai.

The CBI was 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 were 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.

The apex court had made it clear that the emphasis of the investigation would be to determine the loss of money to the public exchequer and said a progress report on the probe has to be filed by the CBI and Enforcement Directorate in a sealed cover.

Holding that prima facie "serious irregularities" have been found in issuance of 122 licences, the court had delivered a seven-point direction to the CBI and ED saying it was satisfied that allegations need a thorough and impartial investigation.
