Janata Dal-United leader Nitish Kumar on Wednesday took oath as Bihar chief minister for the eight time in a ceremony at Raj Bhawan.
Rashtriya Janata Dal's Tejashwi Yadav was administered the oath of office as deputy chief minister.
The no-frills ceremony comes a day after Kumar snapped ties with the Bharatiya Janata Party-led National Democratic Alliance and joined hands with the RJD to form a 'mahagathbandhan' government.
