New Delhi, Jan 7 (IANS): Seeking to make Home Minister P. Chidambaram a party to the 2G spectrum case, Janata Party president Subramanian Swamy Saturday submitted the certified copies of documents and concluded his arguments.

Special Central Bureau of Investigation (CBI) Judge O.P. Saini, after hearing Swamy's plea for prosecution of Chidambaram in the 2G case, listed the matter for Jan 21 for final arguments.

"This evidence reveals the connivance, collusion and consent of the then finance minister Chidambaram in the decision taken by the then telecom minister A. Raja on the matter of fixing prices of spectrum licences and the matter of permitting companies who received licences," Swamy said.

Chidambaram was the finance minister in the first United Progressive Alliance (UPA) government when the spectrum saga began.

Swamy sought to make Chidambaram a party in the case, saying the decision on spectrum pricing was taken in 2008 jointly by him and Raja, who has been lodged in the Tihar Jail here since Feb 2. He alleged that Chidambaram and Raja were equally guilty of recommending spectrum prices based on 2001 rates.

Swamy had earlier submitted three documents for seeking the prosecution of Chidambaram. These included evidence extracted from a Comptroller and Auditor General (CAG) report and other sources, and sought some time to bring more documents related to the scam.

Raja is among the 14 people, including corporate honchos, who have been arrested in the scam. Kanimozhi, a DMK Rajya Sabha MP and daughter of former Tamil Nadu chief minister K. Karunanidhi, was also arrested in connection with the case.
