The Lok Sabha and the Rajya Sabha saw Congress members waving copies of an article in a news magazine with the headline: 'Sweet deals are made of gas' and raising slogans against Modi from the aisle, with some even threatening to troop into the Well.

The article spoke of a "dubious" company registered in Barbados enjoying a windfall of Rs 20,000 crore at the cost of Gujarat tax-payers in the wake of an agreement inked under Modi's watch.

The Lok Sabha was adjourned till 1230 hours and the Rajya Sabha till 1400 hours.

BJP members were on their feet protesting against the Congress action but were dissuaded by their leaders including L K Advani who asked them not to raise counter-slogans and maintain restraint.

The Congress had yesterday demanded an answer from Modi over a report alleging that his government gave a foreign company stake in a gas exploration project virtually for nothing.

It said the Barbados-based company did not pay a single penny for the 10 per cent stake given to it by the Gujarat government.

Noting that the story in the news magazine raised certain questions, which Gujarat government and especially the chief minister must answer, the Congress had asked, "Who is the beneficiary?"

Allegations against Modi baseless: BJP

BJP on Tuesday said the allegations levelled against Gujarat Chief Minister Narendra Modi on a gas deal are “factually baseless, motivated and mischievous” and regretted that Parliament is being disrupted on the issue.

“The repeated adjournment initiated by Congress in both Houses on the Gujarat gas deal is factually baseless and motivated. The Gujarat State Petroleum Corporation has already circulated the Carried Interest Agreement with GeoGlobal Resources in 2010 itself,” BJP chief spokesperson Ravi Shankar Prasad said.

He further maintained that GSPC has also written five letters to ministry of Petroleum and Natural Gas requesting modification of the production sharing contract which has not been done for last more than two years.

“Therefore, the Union Ministry of Petroleum is at fault and there has been no production till date from the gas block nor even a single farthing paid. These allegations against Modi and GSPC are completely baseless and mischievous,” Prasad said.

Meanwhile, Tapan Ray, Managing Director of GSPC, has written a letter to the editor of Tehelka magazine -- which carried the story -- denying all allegations against it as baseless and without complete appraisal of facts.

Congress members had displayed copies of the magazine in the House and raised slogans against Modi. They demanded a CBI inquiry into the matter.

The news report alleges that the Gujarat government's deal has led to a windfall gain of Rs 20,000 crore to GeoGlobal Resources which was given a 10 per cent stake in a gas exploration project allegedly for nothing.
