JD-U spokesperson Rajiv Ranjan confirmed the removal of Sharad Yadav to IANS.
In a tweet Saturday morning, Shah spoke about their meeting on Friday and that he invited Nitish to join BJP's national coalition.
After allying with the BJP in Bihar, Nitish Kumar had been invited to join the NDA.
Acknowledging Mr Yadav's seniority in the party, the JD (U) leader said, "Sharadji is one of the founding members of the party, but it pains us that the path chosen by him leads to our rival, the Rashtriya Janata Dal".
On Saturday morning the representatives of JD (U) wrote a letter to Vice-President Venkaiah Naidu saying that instead of Sharad Yadav, RCP Singh will be the leader of the parliamentary party in the Rajya Sabha and Naidu gave his approval for the change in leader. They have reposed their faith in the chief minister and JD (U) president Nitish Kumar.
"There is no question of leaving the party JD (U)".
"First, Nitish took the decision to go with the BJP without calling the national executive". The decision of the public was against the BJP-led NDA alliance. He had also said that he will stand by his choice and support the RJD joining hands with the Congress through the mahagathbandhan.
He added that this was not a personal fight against Nitish Kumar but a fight of principles and to save democracy and brotherhood. Last night, the JD (U) had sacked Arun Shrivastav, considered a close confidante of Yadav, from the post of party general secretary for "unauthorisedly" writing to the Returning Officer of Gujarat Assembly appointing an election agent for the crucial Rajya Sabha election there.
"Yesterday (Friday) they suspended me from the parliamentary party". Till now, he used to sit in the front benches, sharing the space with other top leaders of other parties.
The party is going to have a committee meeting on August 19 that will take the final decision, Singh said.
