New Delhi, Jan 22 (Agencies): In sign of increasing trouble for former Union Telecom Minister A Raja, a Delhi court on Saturday summoned Comptroller and Auditor General (CAG) Vinod Rai and Director CAG to appear as witnesses on a complaint by Janata Party chief Subramanian Swamy seeking the former's prosecution in the 2G spectrum allocation scam.

Special CBI Judge Pradip Chaddah last evening sought presence of the top auditor and the official, R P Singh, in the court on February 5 to depose as witnesses.

The order came on a private complaint by Swamy seeking registration of a criminal case against Raja for his alleged role in the scam, which, according to the CAG, caused a presumptive loss of 1.76 lakh crore to the exchequer.

The court had on January 7 held as "maintainable" the private complaint filed by Swamy on December 15 last year.

He had made a three-fold prayer which included that his complaint be taken cognizance of and Raja be summoned to take the case to its logical conclusion.

As per the second prayer, Swamy wanted the court to appoint him "as a deemed public prosecutor under the provisions of the Prevention of Corruption Act."

As per his third prayer, Swamy wanted the court's directions to agencies like the CBI and Enforcement Directorate (ED) to assist him in conducting prosecution and
in the further investigation into the scam.

Quoting from the CAG report, Swamy had alleged that Raja committed fraud by adopting the first-come-first-served basis in allocating Spectrum to ineligible companies.

The court had on the day of previous hearing said that first of all Swamy will have to depose as a complainant in the case and then only his plea, seeking appointment as a deemed
public prosecutor, could be decided.
