Patna / New Delhi, May 18 (ANI): Nitish Kumar's resignation from the post of Bihar's chief minister has triggered speculation over who among the JD (U) legislators would be the next chief minister of the state. Kumar has not recommended dissolution of the assembly, this leaving a window for formation of a new government, if any other party cobbles up majority in the 243-member house. The JD-U legislators will meet on Sunday evening to elect their new leader. A senior JD-U leader Narendra Singh, who is believed to have been leading a quiet rebellion within the party against Kumar for breaking 17-year old alliance with the Bharatiya Janata Party (BJP), refuted speculation that he could be the new chief minister.
