A parliamentary panel on IT headed by Congress leader Shashi Tharoor is likely to question top government officials, including from Home Ministry, next week on allegations related to phone tapping of many using Pegasus spyware, sources said on Wednesday.

An international media consortium has claimed that several Congress leaders including Rahul Gandhi, two union ministers, Trinamool Congress leader Abhishek Banerjee and some 40 journalists were among those whose phone numbers were listed as potential targets for hacking through the Israeli spyware which is usually supplied to government agencies.

The Indian government and Israeli surveillance company NSO Group, which sells Pegasus spyware worldwide, have refuted the reports.

The 32-member Parliamentary Standing Committee on Information and Technology headed by Tharoor is scheduled to meet on July 28. The agenda of the meeting is 'Citizens' data security and privacy', according to the notification issued by Lok Sabha Secretariat.

The panel, which has maximum members from the ruling BJP, has summoned officials from the Ministry of Electronics, Information and Technology and the Ministry of Home Affairs.

Sources in the panel said the Pegasus phone tapping issue will definitely be raised in the meeting and details will be sought from the government officials.

The issue also rocked proceedings in Parliament as opposition parties launched a scathing attack on the government.

Describing the entire snooping incident as a matter of "national security concern", Tharoor had demanded an explanation from the government.

Speaking in Lok Sabha, Union IT and Communications Minister Ashwini Vaishnaw had dismissed the reports as "baseless" and said that the allegations levelled just ahead of the Monsoon session of Parliament were aimed at maligning Indian democracy.
