New Delhi: Rajya Sabha proceedings were adjourned in pre-lunch session on Wednesday without transacting any business following an uproar over BJP MP Sushmita Dev's alleged derogatory remarks against CPM's John Brittas. Amid a ruckus, Chairman C P Radhakrishnan, who ruled that he would call the concerned MPs to his chamber to discuss the issue, adjourned the proceedings till 2 pm. Brittas had had earlier moved a privilege motion against Dev for addressing him as "lungiwala" during proceedings in the Upper House on Monday. Meanwhile, some Opposition MPs led by those from Congress demanded the Leader of the Opposition Mallikarjun Kharge to be allowed to speak. As the two sides indulged in a slugging match, the Chairman adjourned the proceedings till 2 pm.
