New Delhi: The political slugfest between Congress and BJP over the two parliamentary committees – PAC and JPC - probing the 2G spectrum scam fails to die down.

The ruling Congress on Friday launched a scathing attack on senior BJP leader Yashwant Sinha, who was a member of the Public Accounts Committee and has now been made a member of the Joint Parliamentary Committee.

Congress spokesman Abhisek Manu Singhvi said on Friday that Sinha has no right to be on the JPC as he has breached the Parliamentary norms and precedence.

Congress has taken on Sinha after his tirade against Union Home Minister P Chidambaram for his decisions in the capacity of finance minister when the 2G spectrum scam was perpetrated.

Terming Sinha’s remarks and charges against Chidambaram as defamatory, Singhvi said that the person (in reference to Sinha) whose role should be inquired is probing the scam.

Questioning the role of Pramod Mahajan and Arun Shourie – both minster of telecom in NDA government, Singhvi said, “Sinha forgot the actions of his erstwhile telecom ministers Pramod Mahajan and Arun Shourie.”

Notably, the second meeting of the JPC is slated on May 18. Congress has made it clear that it would not give a free hand to the Opposition in the committee.

Sources said congress is planning to make a formal complaint against Sinha with Lok Sabha Speaker Meira Kumar asking her to remove the BJP leader from the JPC.

Congress is also planning to rake up the statements made by the BJP leader in a party convention terming it as a breach of the parliamentary committee’s privileges and precedence.
