"Met Vice President & gave in writing that we have elected RCP Singh as our leader in Rajya Sabha", state JD-U president Vashishtha Narayan Singh was quoted as telling news agency ANI.
Sharad Yadav is unable to come to terms with the change and he is disagreeing with the Chief Minister Nitish Kumar.
Also, he took a dig at Yadav for calling Nitish Kumar's JD-U "sarkari party" saying: "When he (Yadav) was minister in the NDA government, then it was not a sarkari party but a revolutionary party. All the party legislators, leaders, who are close to the government for personal benefit are with Nitish, but leaders and workers close to the people are with me", Sharad said. The RJD chief said that he was accused of speaking to Sahabuddin, a tainted politician, but at the same time, there is no issue on Chief Minister Nitish Kumar is speaking to Anant Singh, another tainted politician from Bihar.
The cracks in JD (U) have now become so big that it would be impossible to save the structure.
On Thursday, Sharad Yadav had said that he was still with RJD, Congress-led Mahagathbandhan. Senior party MP R.C.P. Singh may be the likely replacement.
Meanwhile, PM Narendra Modi will be meeting Nitish again in August-end to discuss the Bihar package.
Anwar was suspended from the JD (U) parliamentary party for participating in the Opposition meeting called by Congress president Sonia Gandhi.
The JD (U) spokesperson alleged that Sharad Yadav won from Madhepura with the BJP's support in 1999.
He added that this was not personal fight against Nitish Kumar but a fight of principles and to save democracy and brotherhood. Today (Saturday), they removed Sharad Yadav, who was the founding member of JD-U, from the leadership of the parliamentary party.
Speculation swirled over his remarks that the party could suspend him.
The JD (U) is expected to endorse a proposal to join the NDA in its national executive meeting in Patna on August 19.
