"He (Yadav) is free to take his decision. As far as the party is concerned, it has already taken its decision. The decision was not mine alone and it was taken with the consent of the party. If he keeps a different opinion, then he is free to do so," Nitish told reporters after meeting Prime Minister Narendra Modi.
It was his first visit to the national capital after he dumped grand alliance partners -- the RJD and the Congress -- and sealed a tie-up with the BJP.
Yadav, who is the leader of the party in the Rajya Sabha, is on a tour to Bihar.
Yesterday, he had said he remained with the grand alliance. He also claimed that the real JD(U) is with him and the one with Kumar was 'sarkari' JD(U).
