Season 3: Nitish Returns to NDA
And then came one of the most dramatic episodes in Indian politics. Nitish Kumar resigned in January 2024 as CM, jumped back to NDA, and took oath for the ninth time.
The INDIA bloc fell apart in the state as Nitish accused the Congress of trying to dominate the alliance and delaying seat talks. The BJP alliance welcomed him back.
