Sharad Yadav lost the Lok Sabha election from Madhepura constituency last month.
Party legislator Neeraj Kumar, considered close to Nitish Kumar, hinted at the likely stand of the JD-U when he requested the party not to field any candidate as the seats did not belong to the party.
The three seats were vacated after the Lok Sabha elections by BJP leader Rajiv Pratap Rudy, LJP chief Ram Vilas Paswan and Ram Kripal Yadav, who was an RJD MP but quit the party and contested as a Bharatiya Janata Party (BJP) candidate and won.
Rebel JD-U legislators have threatened not to support official party candidates other than Sharad Yadav.
Two days back, Poonam Devi and Gayanu Singh said over 50 party legislators are in touch with them and threatened to support the formation of a new government in the state.
