The National Democratic Alliance is scheduled to hold a joint legislature party meeting in Patna on Sunday over Bihar election results.
Janata Dal-United chief Nitish Kumar is expected to be elected as the leader at Sunday's meeting.
On Friday, the Bihar Chief Minister had tendered his resignation to state Governor Phagu Chauhan.
This comes as the constituents of the NDA, which secured a majority in the recently concluded Bihar Assembly Elections.
The Bharatiya Janata Party had won 74 seats, JD-U 43, while eight seats were won by other NDA constituents.
