Due to the uproar, the House had to be adjourned for 25 minutes, just five minutes after it met for the day at 11 am.
As soon as the House took up the Question Hour, Jai Prakash Narayan Yadav (RJD) raised the issue of JD(U) leader Nitish Kumar leaving the 'grand alliance' and forming a new government with the BJP.
Shouting from his bench in the front row, he dubbed it as "murder of democracy".
Mr Kumar resigned as Bihar Chief Minister last evening, dumping the 'grand alliance' which also included the RJD and the Congress.
Subsequently, he firmed up an alliance with the BJP and formed a new government with its support this morning. Meanwhile, Congress members trooped into the well of the House, demanding revocation of the suspension of six of its members.
They carried placards which read: "End discrimination, give justice madam Speaker" and "take back suspension (of six party MPs)."
The Congress members were also demanding initiating discussion on "mob lynchings".
Due to the din, Speaker Sumitra Mahajan adjourned the House till 11.30 AM.
However, Speaker Sumitra Mahajan ruled out suspension of the Question Hour, saying she was ready to allow discussion on any issue but only after the Question Hour.
"Please go to your seat. No one refused discussion. I will allow you to speak but only after the Question Hour," she said.
Congress leader in Lok Sabha Mallikarjun Kharge said they first want a discussion on the issue of lynchings by cow vigilantes.
As the opposition members ignored Ms Mahajan's request, she told the protesting members that they were disturbing the proceedings of the House.
"Your are disturbing the House. The whole country must see. Let everyone see," he said.
But she did not adjourn the House and the Question Hour continued amidst the sloganeering by opposition.
