Prashant Kishor today predicted that opposition unity against the BJP in 2024 would "never work" as it would be unstable and ideologically disparate. The ace election strategist also questioned the benefits of Rahul Gandhi's Bharat Jodo Yatra. Opposition unity, he said, is a facade and wouldn't be possible just by bringing parties or leaders together. "If you want to challenge the BJP, you have to understand its strengths - Hindutva, nationalism and welfarism. It is a three-level pillar. If you can't breach at least two of these levels, then you can't challenge the BJP," Prashant Kishor said in an exclusive interview to NDTV.
