Chairman M Venkaiah Naidu repeatedly reminded members of their conduct and asked them to returned to their seats. However, his pleas went unheeded, forcing him to adjourn the proceedings till 1200 hours.
No sooner had the listed papers been tabled, Congress members were up on their feet demanding an explanation from the Prime Minister on his remarks against Singh.
Naidu disallowed them.
At this point, Congress members rushed to the Well of the House shouting slogans.
Naidu asked them not to create obstruction and allow other members to raise important issues.
"This is not the way," he said. "This is Parliament. This is Rajya Sabha. Wrong message is going."
Stating that he did not appreciate their behaviour, Naidu said, "Please dont exceed limit. Please go to your seat."
With his pleas going unheeded, Naidu adjourned the proceedings till noon.
