The former Finance Minister said it was certainly unbecoming of anyone to say such "harsh and ugly" words against Singh."This is an insult of the House…we have never seen such arrogance. We condemn the Prime Minister’s remarks."Replying to a debate on the Motion of Thanks to the President’s Address in the Rajya Sabha, Modi tore into Congress and took on Singh who had described demonetisation as "organised loot" and "legalised plunder", saying "the art of bathing in a bathroom with a raincoat on" is known only to the former Prime Minister as there is "no blot on him" despite "all the scams". He said Manmohan Singh occupied various positions and one must learn from him how to take a shower wearing a rain coat.The Congress also dubbed Modi as "arrogant" and charged him with bringing the debate to "the lowest level". He also insulted the former late Prime Minister Indira Gandhi. He has dragged the debate to the lowest level.. We are very very disappointed and angry (with) what the Prime Minister said.

This provoked an angry reaction from Congress members who staged a walkout in the midst of the reply by the Prime Minister.""It was in extremely poor taste. It is unbecoming of a Prime Minister to use such language against a former PM.Targeting Modi, senior Congress leader Anand Sharma said, "He is behaving in an arrogant and insulting manner against the opposition.New Delhi: Hitting back at Narendra Modi, Congress on Wednesday said the words used by him in the China shower sliding bar Factory Rajya Sabha against former Prime Minister Manmohan Singh were "extremely poor" in taste and "unbecoming of a Prime Minister" and demanded that he apologise to the House. He should apologise to the House for this," he said. We expressed our protest by walking out (from the House)," senior Congress leader P Chidambaram said.Accusing Modi of "arrogance", another Congress leader, Kapil Sibal, said that the Prime Minister has "insulted" the House with his remarks and he must apologise."Within minutes of his speech, he attacked the former Prime Minister in the most unacceptable manner. The Prime Minister should think that there is a stature to the post he holds and he does not know what words should be used…We will not tolerate this.
