Telecom Minister Kapil Sibal's comments that there was no loss in coal block allocation as there was no mining today drew severe criticism from BJP which alleged he has not learnt lessons from similar theory he had propounded in the 2G spectrum case.

"The comments of Kapil Sibal that there is no loss as there was no mining of coal shows once again that he has not learnt any lesson. He had to suffer public ridicule on his zero-loss theory in the 2G spectrum case," Deputy Leader of BJP in Rajya Sabha Ravi Shankar Prasad told PTI.

BJP maintained that while the base price for 2G spectrum was fixed at Rs 1,658 crore it has been determined at Rs 14,000 crore at the re-auction done recently.

"This new base price of Rs 14,000 crore was determined by his own government's EGOM headed by Union Minister P Chidambaram and that too under adverse market conditions prevailing in 2012," Prasad said.

BJP said a coal mine going to a company adds to its net worth and maket value.

"They have not paid a single Rupee for it and have not mined it in the last 4-5 years and government has lost huge opportunity cost," Prasad said.

BJP alleged these comments from Sibal show the government does not want a debate on the coal allotment issue.

"If this is the kind of debate Congress wants, it reinforces once again that the government is not serious about debate and runs away from accountability," Prasad said.

On Sibal's comments that BJP's ideology was used to kill Mahatma Gandhi, BJP said the Telecom Minister has entered politics late in life and should study recent history to know the truth.

"This comment of Kapil Sibal is not only regrettable, irresponsible but also condemnable. So many commissions have after extensive inquiries held this charge to be completely baseless," Prasad said.

Taking jibes at Sibal, he said "Sibal is comparatively new to politics. He came into politics only in 1990s and therefore he needs to study the political history of India a little more."

Sibal had alleged the "ideology" used to assassinate Gandhi is being used now to "kill" Indian democracy.

"BJP does not think about the nation. It wants to come to power before 2014. It just believes in the ideology of disruption and killing of democracy," Sibal had said.
