With Special CBI Judge O P Saini having taken the wind out of its campaign against Home Minister P Chidambaram, a disheartened BJP on Saturday harped on his “political accountability” in the 2G spectrum scam. Party spokesperson Ravi Shankar Prasad, who was extremely combative in attacking the government just two days ago following the Supreme Court’s order cancelling 122 telecom licences, said that the party would continue to seek “accountability” of Chidambaram and the government in the case.
