Chairman Hamid Ansari asked members to sit down and let the Question Hour be taken up. But they were unrelenting.

PJ Kurien, who was in the chair, tried to take up the short notice question on whether companies may lose Rs 6,000 crore every year due to cut in spot sales of coal.
As YS Chowdhury (TDP), in whose name the question was listed, did not put it, coal minister Sriprakash Jaiswal laid his reply in the din and no supplementary question was asked.
All the while, members from BJP and AIADMK shouted slogans demanding the Prime Minister's resignation and some members from DMK and the Left displayed placards saying, "Stop Training the Sri Lankan Army."
In the din, the government moved the All India Institute of Medical Sciences (Amendment) Bill 2012, which however could not be passed due to uproar by the BJP.
Kurien asked members to go to their seats saying the bill had to be passed as it was very important.
However, as members remained unrelenting, he adjourned the House till 2pm.
