New Delhi, Dec 22 : Rajya Sabha Chairman M.

The Rajya Sabha was adjourned sine die on Wednesday, a day ahead of the schedule. Naidu expressed his concern and unhappiness over the functioning of the House. In his brief valedictory remarks, Naidu urged the MPs to collectively reflect and individually introspect on the way the session has gone by. He observed; "The winter session of the august House concludes today. I am not happy to share with you that the House functioned much below its potential. I urged all of you to collectively and individually reflect and introspect if this session could have been different and better. I don't want to speak elaborately on the course of this session as it would lead me to take a very critical view. Statistics regarding various aspects of functioning of the House during this session will be released to the media for wider dissemination." The Rajya Sabha clocked productivity of 47.90 per cent during the 18 sittings of the winter session that concluded Wednesday.
