Minister of State for Defence Ajay Bhatt, while replying to a question in Rajya Sabha on Monday, said, “Ministry of Defence has not had any transaction with NSO Group Technologies.” Reacting to the development, Chidambaram tweeted, “MoD has ‘absolved’ itself of any deal with the NSO Group, Israel. Assuming, MoD is correct, that takes out one Ministry/Department.What about the remaining half a dozen usual suspects?” “Only the PM can answer on behalf of ALL ministries/departments. Why is he silent?” the former home minister said.
