Bihar Chief Minister Nitish Kumar has resigned from the state legislative council today, ending his two-decade tenure in one of India's most politically crucial states. Kumar's election to the Rajya Sabha weeks ago triggered the resignation under constitutional rules preventing simultaneous membership in state and national legislatures. Deputy Chief Minister Samrat Choudhary of the BJP emerges as the frontrunner to succeed him, potentially giving the BJP greater control over Bihar's government following the NDA's landslide victory in 2025. JD(U) leaders have proposed Kumar's son Nishant as an alternative successor. BJP national president Nitin Nabin, also elected to the Rajya Sabha, must similarly resign as an MLA to comply with the Prohibition of Simultaneous Membership Rules. The political transition marks a significant shift in Bihar's governance structure and power dynamics.
