The Centre on Monday stating national security reason told the Supreme Court it does not wish to file a detailed affidavit clarifying whether Pegasus spyware was used or not as it responded to a batch of petitions seeking independent probe into the alleged Pegasus snooping.

Solicitor General Tushar Mehta, representing the Centre, submitted before a bench headed by Chief Justice N.V. Ramana that the government will disclose all details in connection with the Pegasus case before a panel of domain experts but not on an affidavit for national security reasons.
