Faced with repeated disruptions in the House and a strong admonition from Lok Sabha Speaker Somnath Chatterjee over the suspected “leakage” of the Justice R S Pathak panel report on the Iraq oil scam, the government today said ‘‘firm action would be taken against those responsible for the reported leakage.’’

Pinning down the government on the leakage of the report indicting former External Affairs Minister K. Natwar Singh and his son Jagat Singh, the BJP was on the offensive today in both Houses of Parliament.

While the Speaker sought ‘‘an explanation from the government’’ on how the contents of report appeared in the media before it was tabled in the House, the opposition (that is, BJP aided by Samajwadi Party) levelled corruption charges against Congress president Sonia Gandhi with Leader of the Opposition L K Advani providing the slogan of the day: ‘‘Congress ka lafra hai, Natwar Singh to bakra hai.’’

Opposition members strongly contended that the Congress party, which has been named along with Natwar Singh as a non-contractual beneficiary, could not be let off the hook without strictures.

The agency which will probe the leak will be “decided in a day or two,” said Parliamentary Affairs Minister Priya Ranjan Dasmunsi. He said that a TV channel (CNN-IBN) began broadcasting on the report ‘‘even before the sealed envelope had reached the Prime Minister’s Office.”

“The PM himself is yet to see (that is read) the report,’’ Dasmunsi said. As per procedure the PMO sent the ‘‘sealed envelope’’ to Finance Minister P. Chidambaram. And, Chidambaram, in turn, said, he’s ‘‘yet to open the envelope’’.
