Lok Sabha has been adjourned till 12 noon following opposition protest during Question Hour. When the Lok Sabha assembled for the day, Lok Sabha Speaker Om Birla expressed concern over the behaviour of the opposition members, who reached near the treasury benches yesterday, shouting slogans. He said the behaviour of the opposition members was not appropriate and it is against the dignity and decorum of the House. Mr Birla emphasised that maintaining the decorum of the House is the collective responsibility of all the members. He added that if the dignity of the House is not maintained, then it will be difficult for any Speaker to conduct the smooth proceedings of the House.
