The Bhartiya Janata party on Wednesday gave a new twist in the 2G spectrum case alleging that Home Minister P. Chidambaram as finance minister in 2007 played a role in fixing the price at which the 2G spectrum was allocated. The party demanded his resignation. 
 
The party spokesperson Nirmala Sitharaman said that the Supreme Court had also asked for the transcript of taped conversation between corporate lobbyist Niira Radia and former communications minister A. Raja related to Chidambaram.

She said petitions had also been filed to probe Chidambaram''s role in the scam.

"In fixing price for allocation of 2G spectrum in 2007 at the price of 2001, clearly the then finance minister had a role. This is a very serious issue on which the government needs to explain the role of the then finance minister," she said.

"Despite a lot of questions being raised from various quarters, the prime minister is silent," she added.
