Patna: JD(U) leader Nitish Kumar on Wednesday took oath as Bihar chief minister for the eighth time in a ceremony at Raj Bhawan.
RJD'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 BJP-led NDA and joined hands with the RJD to form a Mahagathbandhan' government.
Besides JD(U) and RJD, the Congress is expected to be represented in the new cabinet. Left parties CPI(ML)Liberation, CPI and CPI(M) have expressed their intention to support the new government from outside.
Kumar had on Tuesday quit the BJP, stripping the party of power, before resigning and staking claim to form a new government, armed with the support of the Mahagathbandhan' (Grand Alliance).
The 71-year-old JD(U) leader first took oath as chief minister in 2000, when he headed an NDA government that lasted only a week. He was back in 2005, this time with his coalition having won an absolute majority in the assembly polls.
The NDA won a landslide victory under his leadership in the assembly polls five years later. Kumar stepped down in 2014, owning moral responsibility for the drubbing of JD(U) in the Lok Sabha polls, but returned less than a year later when he was sworn in for the fourth time.
In 2015, Kumar was back as CM, with the Grand Alliance then comprising the JD(U), RJD and Congress winning a comfortable majority. He resigned in July 2017, citing irreconcilable differences with the RJD, and got sworn in again less than 24 hours later, when he formed a new government with the BJP.
Kumar was sworn in for the seventh time in November 2020, when the NDA retained power, though his own party saw a major fall in its tally for which it blamed a conspiracy by the BJP.
