BJP leader Manoj Tiwari responded to Delhi Chief Minister Arvind Kejriwal's comment on NRC. Tiwari said Kejriwal has lost mental stability and is not fit for the post of chief minister. “People who have migrated from other states are considered as foreigners by you (Delhi CM)? You want to chase them out from Delhi,you're one among them. If this is his intention then I think he has lost his mental stability. How does an IRS officer not know what NRC is? the BJP leader said. Chief Minister Arvind Kejriwal on Wednesday said that BJP leader Manoj Tiwari, who has been demanding National Register of Citizens (NRC) in the national capital, will have to leave Delhi if such a list was compiled.Kejriwal made the statement while responding to a question on the BJP's Delhi chief Tiwari saying that illegal migrants were responsible for the increase in crime in Delhi. “If NRC was implemented in Delhi, Tiwari will have to leave first,” the Chief Minister said.
