New Delhi, Sep 28: CBI and former Telecom Minister A Raja strongly opposed any further investigation in the alleged role of Union Home Minister P Chidambaram in the 2G scam.

Senior counsel  of CBI K K Venugopal straight forward refused to investigate the role of former finance minister Mr P Chidambaram and also slammed the Government and contended that CBI is an autonomous agency and Government cannot make any statement or give any undertaking on behalf of the CBI.

At the same time Senior Counsel of Araja Sushil Kumar opposed the plea for CBI probe into the role of Mr Chidambaram saying that the trial proceedings against his client are getting delayed and the bail application of his client is stuck up as charges are not being framed in the case.

Earlier Senior Counsel P P Rao appearing for the Government had told the Apex Court during the last hearing that CBI will look into the note of Union Finance Ministry sent to PMO saying "The 2G scam could have been prevented had Mr Chidambaram insisted on the sale of Spectrum through auction.

" Mr Subramanian Swamy who has filed an application for CBI probe into the role of Union Home Minisrer Mr P  Chidambaram, who was the Finance Minister at that time had produced a note dated March 25, 2011 submitted by Deputy Director in the Department of Economic Affairs along with a document which shows that Mr P Chidambaram had allowed the sale of 2G Spectrum at 2001 rates on 'first cum first serve' basis.

The exchequer got only Rs 1650 crore and the companies that were given licenses made hundreds of crores as profit  by selling the stakes to foreign partners.

Mr Prashant Bhushan, Counsel for Centre for Public Interest Litigation will start his arguments today before a bench comprising Justices G S Singhvi and A K Ganguly pleading for setting up of an SIT for probing the role of Mr Chidambaram.
