Janata Party president Subramanian Swamy today filed a petition in a Delhi court seeking his inclusion as a public prosecutor in the 2G spectrum case.

In his petition filed before special CBI judge Pradeep Chaddah, Swamy pleaded that the court should take cognisance of his plea.

Swamy submitted that he may be appointed as a public prosecutor in the case and also sought a direction from the court that the CBI should assist him in the investigation.

After hearing Swamy, the court reserved its order for January 7, 2011 on his complaint also seeking prosecution of former Telecom Minister A Raja in the case.

Swamy approached the CBI court following up on the Union government's argument late last month in the Supreme Court that there was no question of granting sanction to prosecute Raja when there was no complaint filed against him in a competent court.

Attorney General G E Vahanvati had contended this while terming Swamy's communication to Prime Minister Manmohan Singh for grant of sanction against Raja as "misconceived and premature".
