The Upper House also saw heated exchanges between the opposition and treasury benches over the issue, with Congress alleging that corporates were running the government and the ruling BJP saying such espionage has been happening in almost all departments for the past 10 years of UPA rule.
Raising the issue during Zero House, Pramod Tiwari (Cong) said the House should rise above party politics and set up a JPC with members of various parties to probe the issue as it concerned matters of national security.
Tiwari also charged the government of being "run" by industrialists and for working for them and asked how the ministers "who cannot protect their own ministries, can run the country".
Countering the charge, Vijay Goel (BJP) expressed surprise that a party like Congress was raising the issue and alleged that such leakage of papers was not only going on but "went on uncontrolled" during the past 10 years of UPA rule.
