The party rejected the Prime Minister's contention that opposition was trying to destabilise the government, saying it did not have the numbers to do so but the "collapse" was taking place due to its own contradictions.
At a press conference held to take on the UPA government after Singh's statement yesterday, Leader of Opposition in Lok Sabha Sushma Swaraj and her Rajya Sabha counterpart Arun Jaitley made a scathing attack on the Prime Minister, alleging that the files clearly show he had "full knowledge" and was not in the dark about the 2-G Spectrum allocation scam.
Demanding the resignation of Chidambaram, the BJP leaders said "the last word has not been said on 2G" and the "2G saga is continuing".
"The March 25 note of the Finance Ministry accessed through RTI shows clearly para by para that the then Finance Minister (P Chidambaram) not only had the knowledge but it had his approval as well," Swaraj said.
"So the wrongdoings committed by Raja have also been committed by Chidambaram," she added.
She alleged that UPA was following a "unique coalition dharma" where when a coalition partner is guilty he is trapped while when a Congress leader is guilty he is saved.
"The Prime Minister should save his house instead of blaming the opposition... He should not heap all the blame for this on the opposition and give a clean chit to his ministers," Swaraj said.
