Here is your 10-point cheat-sheet to this story:
Tejashwi Yadav, 28, has been named in a corruption case along with father Lalu Prasad Yadav. The case accuses Lalu Yadav of venality during his term as Railway Minister at the centre to acquire a sweetheart deal for three acres of land in Patna, jointly owned by Tejashwi, his mother Rabri Devi and his siblings. The Central Bureau of Investigation (CBI) last week raided the residence of Lalu, also named in the case, and other properties in five cities.
Lalu Yadav's party, the Rashtriya Janata Dal or RJD, has indicated that it is under no pressure as it has the most seats in the Bihar assembly - 80 of 234. "Tejashwi will not resign at any cost. The RJD has 80 legislators. We will do what we want," party leader Bhai Virender said in Patna.
Nitish Kumar's party retaliated by asking the RJD to shrug off the "arrogance". "The RJD, which is showing the arrogance of 80 MLAs, should not forget that it was reduced to 22 MLAs in 2010 state poll," said Sanjay Singh of the JD-U.
The JD-U has 71 MLAs and the third alliance partner Congress 27, while the BJP, which is the main opposition party in the House, has 53 legislators and has already volunteered external support - siding with Nitish Kumar in a vote to keep him in office - if Lalu Yadav's party RJD withdraws support.
Lalu Yadav, however, has indicated that he will do what it takes to keep the Bihar alliance intact."I will not allow the maha-gathbandhan (alliance) to suffer" he told ndtv.com on Thursday evening, signaling that his son Tejashwi may eventually yield the resignation sought by Nitish Kumar.
Dismissing the charges against his son as "flimsy", Lalu Yadav told ndtv.com that his son's resignation will encourage the CBI and other agencies to frame other ministers. "It is the people of Bihar who voted for Tejashwi, and when our party has met and decided he should not resign, who are these people who have neither elected nor selected him to ask for his removal?" Mr Yadav has alleged that the CBI raids are blatant persecution by PM Narendra Modi of political opponents.
Sources in the RJD say that furious negotiations between their camp and that of the Chief Minister are underway to decide the modalities of Tejashwi Yadav's exit. What the Yadavs reportedly want is enough time for Tejashwi to present his case.
Any breakthrough, however, is likely to be about as effective as a Band-Aid for a gaping wound, said JD-U sources who believe the Chief Minister is determined that it is time to end his association with the Yadavs, whose increasing stack of corruption charges is turning into a multi-car pile-up.
Lalu Yadav was barred in 2013 from holding public office after he was convicted in another corruption case that goes back to the 90s when he was Bihar Chief Minister. His children are now ensnared in a number of cases that include alleged money-laundering.
Any crack in the JDU-RJD alliance could rearrange the government in Bihar as well as national political partnerships. Nitish Kumar has been accused by his allies, which include the Congress, of being open to propositioning by their rival, the BJP. Mr Kumar stood staunchly behind the PM's sudden ban on high-denomination notes in November and also supported the BJP's candidate for President, breaking rank with opposition parties.
