A court here will rule today whether or not Home Minister P Chidambaram, who was the finance minister when a former communications minister allocated 122 telecom licences that have now been cancelled by the Supreme Court, should be made a co-accused in the 2G spectrum scam.

CBI Special Judge O P Saini had reserved his order for today following the last hearing on January 21 after Janata Party chief Subramanian Swamy, who has made the plea for making Chidambaram a co-accused, concluded his final arguments.

The SC, while cancelling the 122 licences, left it to the trial court to decide on Swamy's plea. Swamy, while deposing against Chidambaram before Saini, had said that former communications minister A Raja committed irregularities in connivance with Chidambaram in alloting the licences. He said the decision on pegging spectrum prices based on 2001 rates was jointly taken by Raja and Chidambaram.

Swamy has submitted documents, including evidence extracted from a Comptroller and Auditor General report, before the court showing Chidambaram's alleged complicity in the case.u00a0
