"It was an alliance of faith for five years and I am deeply hurt with its disintegration", Sharad told mediapersons at Patna airport.
On Thursday, Sharad told reporters that he would undertake a yatra (journey) across the state to speak to the voters.
Hundreds of his supporters, including some JD-U leaders, welcomed Yadav as he came out of the airport, shouting slogans in his support. The fall of the Grand Alliance government was seen as a huge blow for opposition unity, and many in Bihar feel that Nitish Kumar betrayed the popular mandate, which overwhelmingly backed the Grand Alliance over the saffron coalition in 2015.
Another major step that Sharad is taking towards parting with the party is just 10 days ahead of the JD (U) party meet he is set out on a three-day public interaction programme to know the reactions of people on the break up in the grand alliance starting from Thursday. will visit at least 28 places, including Darbhanga, Supaul, Saharasa, Muzaffarpur and Madhepura.
On the other hand, the Rashtriya Janata Dal (RJD) has been extending outside support to Sharad Yadav. There is also speculation that Mr Yadav was looking at joining the RJD to redeem his secular image, which he considers to be dented by his party's switching sides to the NDA in Bihar.
"I was one of those who asked the people to vote for the Grand Alliance".
Sharad Yadav, the second-in-command of the party, is now leading a group of rebel leaders unhappy with Nitish Kumar's sudden breakaway from Mahaghatbandhan, an alliance of JD (U), RJD and the Congress, reported the Hindustan Times. "I still back the mahagathbandhan and stand with it". Neeraj Kumar said that party's Muzaffarpur district unit has send a proposal to initiate disciplinary action against Ramai Ram. First, at some stage, they all went rogue against their own party leadership.
Sharad Yadav wants to be expelled from the JD (U) because that will mean he does not lose his Rajya Sabha membership, which will happen if he resigns.
RJD MLA from Sonepur Ramanuj Prasad shared platform with Yadav at the function. "Nitish ji should answer to people how he is running government with such tainted people", Tejashwi said.Coming down heavily on the CM for breaking Mahagathbandhan, he said, "Aisa koi saga nahi, jise Nitish ne thaga nahi".
The national executive meeting of the JD (U) is scheduled on 19 August and a decision might be taken on Yadav before that. "This is his personal tour", JD (U) spokesperson Niraj Kumar said.
