Opposition parties staged a walkout from the Rajya Sabha after their notices for discussions were rejected. The opposition MPs raised slogans after the deputy chairman of the House, Harivansh, said a dozen notices under Rule 267 had been rejected. Union minister J P Nadda termed the walkout \”irresponsible behaviour\” and suggested that the opposition MPs, including Congress chief Kharge, should go for a refresher course. He also termed the practice of opposition MPs giving notices despite elaborate ruling by the chair a \”vicious design to demean the institution of Parliament\” \”The government under Prime Minister Narendra Modi is ready to discuss anything under this roof. But there are certain rules and regulations for debates in the House,\” he said. The MPs will get an opportunity to raise their issues during the debate on the Union Budget over the next 10 days, he said, adding that the government is ready for that discussion. The walkout was led by the Congress, which demanded discussions over the alleged lapse by the Election Commission in issuing multiple ‘duplicate’ voter ID cards across states.
