"Be assured of our cooperation in the conduct of proceedings."

He, however, added, "Fair and impartial conduct of proceedings, providing just opportunity to members of each party, is essential for credibility of this office."

Kharge also referred to Prime Minister Narendra Modi's statement at the beginning of the Winter Session, and said they would respond later.

"Secondly, PM gave a statement outside (Parliament). He attacked us indirectly as well, we will reply to it here..." he added.

Parliamentary Affairs Minister Kiren Rijiju, meanwhile, slammed the Leader of Opposition for mentioning Dhankhar's resignation on the "solemn occasion."

"This is a very solemn occasion...The Prime Minister has made very dignified remarks as part of the felicitation event...Why did the honourable Leader of Opposition refer to a case which was not necessary to be raised at this moment..." Rijiju said.

"The language you used for the former chairman, the way you insulted him, the motion you served, we still have that copy..." he said.

He was referring to a motion for the removal of the Vice-President submitted by Opposition parties when Dhankhar was in office.

Leader of the House JP Nadda also intervened, urging members to maintain the dignity of the occasion.

He also referred to the loss faced by the opposition alliance, including Congress, in the recent Bihar assembly polls.

"This program is a pious occasion. We should maintain the dignity of the occasion. The issue that the Leader of Opposition raised, if we start discussing this, it is irrelevant...We will also have to mention that you brought a no-confidence motion against him twice. It is an obstacle in a good and congenial environment debate which is going on," Nadda said.

"Talking about what the Prime Minister said outside...The loss of Bihar and Haryana must have given you a lot of pain...But you should express your pain and suffering to a doctor. You should speak to a doctor when the time comes," he added.

Addressing the media on the first day of the Winter Session of Parliament, Prime Minister Modi said the opposition was perturbed by the electoral losses in Bihar and was unable to digest its failure.

"Defeat should not be the ground to create disruption. Victory should not convert into arrogance either," the prime minister said.

Parliament is not a place for drama, it is a place for delivery, he said, adding it should not be used by the Opposition to vent out frustration after defeat in elections.
