Bihar Chief Minister Nitish Kumar has stirred political uncertainty in the state amid speculations about his potential move to join the BJP-led NDA alliance. This marks his fourth such move in the past decade and the second during his current term. Reports suggest that Nitish Kumar's Janata Dal (United) might exit the ruling coalition with ally Rashtriya Janata Dal (RJD) to join the BJP-led NDA, paving the way for him to become Bihar's chief minister once again.
