The Shiv Sena on Wednesday slammed the central government over the Pegasus scandal, saying that such an attack couldn't have happened without the Centre's approval. In the editorial of Shiv Sena's mouthpiece Saamana, the Sena demanded that the issue should be probed by a Joint Parliamentary Committee (JPC). Otherwise, it said, the Supreme Court should take suo motu cognizance and appoint an independent committee.
