Congress today attacked Union Minister V K Singh in the Lok Sabha seeking action against him for his dog analogy and staged a walkout. The Trinamool Congress and the Left too staged a walkout on the issue with the Left seeking action against the minister, who was present in the House. <br/><br/>TMC demanded a regret from him. As soon as the House met for the day, Congress sought to raise the issue but Speaker Sumitra Mahajan said she has disallowed all notices for suspension of Question Hour. Congress members trooped into the Well shouting slogans against the government. Leader of Congress in the Lok Sabha Mallikarjun Kharge said the government during the debate on intolerance did not touch upon the remarks made by General Singh about dalits. <br/><br/>Later, the Congress again raised the issue after the Question Hour. As the Speaker denied permission to raise the issue, Congress members staged a walkout. Parliamentary Affairs Minister M Venkaiah Naidu said General V K Singh did not make such comments about dalits and there is no reason for the opposition to raise the issue again and again.
