The BJP on Saturday attacked the UPA government over filing a chargesheet against the NDA regime in the 2G case and said it has done so to "hide its own corruption" in the case.

"Whenever UPA government gets embroiled in corruption, it attacks BJP and its opponents. This chargesheet is a result of this backlash. When we raised the Commonwealth scam, then this happened. When we raised the coal scam, the BJP state governments were attacked.

"To hide their own corruption in the 2G case, they have filed a charge-sheet against the NDA regime. We condemn this and will take whatever appropriate steps are required in this regard in the court as the matter is now in the court," BJP chief spokesperson Ravi Shankar Prasad said.

The BJP leader said the party will prove that this is a "motivated" action on the part of the government and claimed that it will prove this as per law and it will not hold any ground.

BJP asserted that the Atal-government has a lot of contribution to make in bringing about a Telecom revolution in the country and will fight this charge-sheet in court.

Three telecom companies, including Bharti Airtel and Vodafone India, were on Friday chargesheeted by the CBI in connection with alleged irregularities in the allocation of additional spectrum during the NDA regime which had resulted in a loss of Rs. 846 crore to the exchequer.
