Senior JD (U) leader Sharad Yadav is not happy with the decision of party president Nitish Kumar to form the government with the support of BJP.
Sources say Sharad said it will send a wrong message among people of Bihar.
The senior leader also refused to talk with media when reporters thronged to take his reaction to comment on Bihar political tussle and NDA-JD(U) tie up.
On Wednesday, Citing irreconcilable differences with the senior ally over corruption charges against Tejashwi, son of Lalu Prasad, Kumar announced his resignation after meeting Governor Keshari Nath Tripathi, hours after the RJD supremo rejected outright the demand for his son's ouster.
Later, the BJP had handed over to Bihar Governor Keshri Nath Tripathi the letter extending support to Nitish Kumar for forming the next government.
