New Delhi, Dec 20: The Rajya Sabha saw repeated disruptions on Wednesday and was adjourned till 2 p.m. amid sloganeering by Congress members demanding an apology from Prime Minister Narendra Modi for his remarks against his predecessor Manmohan Singh. The Congress members want Modi to apologize for alleging at an election rally in Gujarat that Manmohan Singh and others at a dinner meeting discussed the Gujarat Assembly election with Pakistani diplomats. As soon as the House met, the Congress members were on their feet. Many had given notice under Rule 267 to suspend all listed business and discuss the issue. However, Chairman M. Venkaiah Naidu rejected all the notices and asked the members to continue with Zero Hour submissions. The Congress MPs then trooped near the Chair's podium shouting slogans. Naidu adjourned the House till noon after his repeated requests to maintain order failed to bring peace. As soon as the Hosue met again for the Question Hour, the Congress members again shouted slogans, demanding an apology from Modi. The Chair then adjourned the House till 2 p.m.
