Former Bihar CM Nitish Kumar was elected as leader of the JD-U legislature party.
Four Janata Dal-United legislators were disqualified on Saturday from the Bihar assembly under the anti-defection law for anti-party activities, including cross voting in Rajya Sabha election.
The BJP on Thursday lent its support to the chief minister even as both houses of Bihar legislature recognised JD-U as their principal opposition party.
Bihar Chief Minister Jitan Ram Manjhi appears to be on the way out in the wake of his defiance as the Janata Dal-United is all set to replace him with his mentor Nitish Kumar at a meeting of the legislature party on Saturday.
