Both Houses of the Parliament were adjourned sine die on Wednesday, a day ahead of its original schedule, marking the end of the Winter Session.

Rajya Sabha Chairman M Venkaiah Naidu adjourned the House sine die soon after laying of the listed papers and reports, saying that he was not happy to share with members that the House functioned "much below its potential".

"I urge all of you to...reflect and introspect if this session could have been different and better. I don't want to speak elaborately on the course of the session that would lead me to make a very critical view," he said.

The chairman stressed that rulings, regulations and procedures have to be followed and said precedents, decency and decorum has to be maintained by members in the House.

He also called on members for "realisation of what has happened is wrong" and said that "we should all work towards a constructive and positive atmosphere for the larger interest of the country".

Naidu wished MPs a Merry Christmas and a prosperous English New Year, and also conveyed his greetings for Makar Sankranti, Pongal and other upcoming festivals.

The Upper House witnessed several disruptions during the session following the suspension of 12 Opposition party members for their "unruly" conduct in the previous session in August.

The Winter Session of Lok Sabha had 18 sittings and witnessed the passage of key legislations such as the Farm Laws Repeal Bill and the Election Laws (Amendment) Bill.

The Lok Sabha session lost 18 hours and 48 minutes to disruption by Opposition members on a range of issues such as price rise and Lakhimpur Kheri violence.

Lok Sabha Speaker Om Birla said the lower house witnessed record productivity of 204 per cent on December 2.

The Winter Session of Parliament had begun on November 29 and was scheduled to go on till December 23.
