In a searing attack in parliament on the government's currency ban, Congress leader Anand Sharma questioned Prime Minister Narendra Modi's comments at a public rally alleging a threat to his life. "Today you have to say who is threatening you, who wants to kill you, answer parliament, we cannot tolerate it. The entire house condemns it if there is a risk to the PM's life," Mr Sharma said, starting a discussion in the Rajya Sabha on the notes ban and its impact.
