Prashant Kishor NDTV Interview: Election strategist-turned-politician Prashant Kishor has doubled down on his charge that Nitish Kumar is not mentally and physically fit to continue as the Chief Minister, even as the JDU leader appears ready to govern Bihar for five more years. "I have no hesitation to say that Nitish Kumar ji is not mentally and physically well," Kishor remarked while speaking to NDTV Editor-in-Chief Rahul Kanwal. Nitish Kumar, 74, will take oath as the chief minister of Bihar for the 10th time tomorrow. Kishor's Jan Suraaj Party (JSP) ran an unsuccessful solo contest in the recent Bihar elections and failed to open its account in debut. But the JSP chief remained defiant and repeated his charge, asserting that he would not take his words back. Asked about such an attack on an elderly man's health, he shot back, "How do you know? I don't have any lens to establish this." "It's not about being older or younger. If you are a chief minister who doesn't appear mentally and physically fit, I would say so. Whether it backfires or not, I am not taking my words back," said Kishor.
