The week started with a discussion on 250th session of the Rajya Sabha with members making 83 suggestions for better functioning of the House during the special debate on the 'Role of Rajya Sabha in Indian Polity and Way Forward'.
As directed by Chairman Naidu, the Rajya Sabha Secretariat compiled the suggestions made by him, the prime minister and 28 members of the House during the special discussion.
Several members suggested changing the composition of the Rajya Sabha for truly reflecting the federal nature of the polity either by ensuring equal representation in the House for all the states as in the case of the US Senate or providing for representation for states and union territories that are not represented in the House now, the statement said.
Many also called for increasing the sittings of the House with some members suggesting a minimum of 100 sittings every year as against the present 60 to 70 sittings per year, it added.
