However, Yadav has rubbished the repeated barbs of a breakup, asserting that all is well with Nitish Kumar.
"Mahagathbandhan is intact and Nitish never asked for resignation from Tejashwi," he said while addressing a press conference in Patna.
Backing his tainted son and Bihar Deputy Chief Minister Tejashwi Yadav, the former chief minister said, the latter won't resign from his post.
Recently, the tension between the 'Grand Alliance' of Congress and RJD had grown as Nitish Kumar was facing increasing pressure to oust Deputy Chief Minister Tejashwi Yadav from the cabinet after charges of corruption were proved against him.
The CBI registered a corruption case against Lalu Yadav, his wife Rabri Devi and son Tejashwi Yadav on allegations of awarding the tender for development, maintenance and operation of hotels in Ranchi and Puri in 2006.
The RJD supremo, however, has refuted the allegations against him and called it a political conspiracy hatched by the BJP.
Meanwhile, the BJP is mounting pressure on Nitish Kumar to oust Tejashwi Yadav from the party.
Senior BJP leader Sushil Kumar Modi said, "Nitish Kumar has no defence so he must immediately suspend Tejaswi Yadav. JD (U) is asking for a response since there has been enough delay in the matter. There is a strong case against Lalu Yadav's son. He has to clarify on the anonymous assets."
Modi also warned that they will not let the House function if an adequate response did not come from the Rashtriya Janata Dal (RJD) supremo.
