BJP MPs Jagat Prakash Nadda, Dharmendra Pradhan and Bhupendra Yadav have sent the privilege notice against Aiyar under Rule 188 of the Rules of Procedure and Conduct of Rajya Sabha to the RS Secretary General.
Aiyar, a Rajya Sabha MP, had during a television debate on logjam in Parliament on FDI in retail, reportedly made the controversial remarks.
"The use of such derogatory and defamatory words is unacceptable and constitutes contempt of this House. Therefore, we feel obliged to raise this question of privilege against him," the notice stated.
The BJP MPs claimed Aiyar had in the televised debate in Bhupendra Yadav's presence referred to MPs shouting slogans in the Well of the House as "animals".
Stating that Aiyar has used and reiterated the word 'Jaanwar' (animal) for MPs, the notice sent by the MPs read "the said offending word has been subsequently used by him several times in the course of the interview and he has justified using the said word on live television."
Earlier members in Rajya Sabha belonging to various parties today raised strong objections to Aiyar's reported comments and demanded an apology.
An apparently embarrassed Minister of State for Parliamentary Affairs Rajiv Shukla tendered an immediate apology on behalf of Aiyar and informed the House that he will talk to him in this regard and ask him to apologise.
