Congress on Friday hit back at BJP leader and former finance minister Yashwant Sinha for endorsing Murli Manohar Joshi's draft for admission as the parliamentary accounts committee (PAC) report on the 2G scam. Congress termed Sinha's stand "biased" and said that he had "lost all moral rights" to continue as a member of the joint parliamentary committee on the scam.

The ruling party contended that the draft had not been put to vote within the PAC and therefore, any unilateral submission was questionable. Party spokesperson Abhishek Manu Singhvi said, " This is a serious matter. BJP believes in bending parliamentary rules according to its convenience. How can Yashwant Sinha comment pending the publication of findings of different probes?"

Sinha had also demanded that home minister (then finance minister) P Chidambaram's in the 2G scam role be probed. The Congress retaliated by saying that while Chidambaram's credentials could not be questioned, telecom ministers of the NDA governmnet Pramod Mahajan and Arun Shourie were being probed.

"This is a premediated attack on the government. Sinha is just carrying out gross politicisation of the issue," Singhvi said.

"His statements reflect an utter alck of knowledege of the issue," the Congress spokesperson added.

Singhvi stepped up his attack and stated that BJP's truth would be out the day the 2G probe findings were published. "BJP bends parliamentary rules according to its convenience. Looks like the party is committed to the violation of constitutional ethics," he said.
