Responding to Maoist plot to kill Prime Minister Narendra Modi, BJP MP Subramanian Swamy said the Union Home Minister and NIA should take up the probe. The cops seized a letter from a residence in Pune on Thursday from one of the five accused linked to the banned outfit. The letter mentioned about carrying out Rajiv Gandhi-type operation to kill Narendra Modi. It also stated that the BJP winning more states apart from 15 states will be a threat to Maoists’ existence. Subramanian Swamy said that he suspected Rajiv Gandhi’s assassination was an inside job.
