Accusing him of "belittling" Parliament and "misinforming" people on the issue at a time when the House is in session, Congress members attacked Modi for "contradicting" his own Commerce Minister Nirmala Sitharaman on the matter.
The House saw two adjournments on the issue during Question Hour as Congress created uproar saying there were inconsistencies in government statements on WTO though Finance Minister Arun Jaitley asserted there was no contradiction.
Attacking Modi for his remarks, Congress member and former Commerce Minister Anand Sharma said, "We cannot allow a situation that Prime Minister of the country will try to belittle and misinform when the House is in session."
"The charge against us is made by none other than the Prime Minister of India. It has to be clarified because it misleads the country...It is the Prime Minister of India who has contradicted his own Minister. He should come to the House and explain," he said.
"The Prime Minister has made disparaging remarks against the previous government," he said, adding that the Commerce Minister has stated that the Government has not deviated from the previous government's stand.
"He must explain. He is contradicting the Minister," he said, as the treasury benches reacted saying he cannot cast aspersions on the Prime Minister.
