Chief Minister Jitan Ram Manjhi, however, said the ruling party may decide on the issue today itself.
"It is true that talks about an alliance between JD(U) and RJD have been generating a buzz of late, but it has to be decided at the leadership level of the two parties and not through the media or discussion in public," state unit JD(U) president Bashistha Narayan Singh said.
"Seat-sharing formula can be worked out later," he said.
Meanwhile, Chief Minister Jitan Ram Manjhi said he will not say on his own about the likelihood of an alliance between RJD and JD(U) as the decision in this regard has to be taken by the party leadership.
A crucial meeting of the party will be held this evening during which the decision on alliance with RJD may be taken, Manjhi said.
