The BJP has meanwhile criticised Congress leader Mani Shankar Aiyar for comparing Opposition Members of Parliament with animals.

Spokesperson Rajiv Pratap Rudy said, "Mani Shankar Aiyar has made a comment in television interview calling members of parliament as animals. Well we absolutely agree on one thing that parliament should not be obstructed, but does this give right to Mr. Aiyar to call members of parliament as animals," Rudy asked.

"Who is Mani Shankar Aiyar?...Mani Shankar Aiyar  is a member of parliament who has been nominated to Rajya Sabha and not even elected.   He subsequently joins the Congress Party. I believe he has been a foreign diplomat. He served in the Indian Foreign Service for over 25 years," he said.

"I am just amused and shocked what he   must have contributed in his 25 years as Indian Foreign officers, the language, which he uses, the behavior which he exhibits especially in the back drop when the Congress party is all being charged with corruption, 2G scam, coalgate and commonwealth games etc.... I think its shocking," he added.

In a television debate on Parliament deadlock over Foreign Direct Investment (FDI) in multi-brand retail, Aiyar said, "There is a decent and respectable way to express one''s point of view. This behavior of the MPs reminds me of animals screaming in a well."

Rajiv Shukla has apologised on Aiyar's behalf in Parliament today.
