If my demand (to appoint someone else as LOP) is not fulfilled, then the legislature party will break as partys several legislators are with me, Yadav claimed. Asked whether he has the support of two-third of RJD legislature party to avoid disqualification under anti- defection law, Yadav answered in affirmative saying that he has the support of large numbers of party MLAs as no one wants to board the sinking ship…but please, dont ask me the names and numbers at the moment. Asked whether he would attend the two-day RJD meeting scheduled to be held on May 28 and 29 to discuss the poll debacle, the rebel MLA said that he would not participate in the meeting till his demand (Tejashwi resignation) is met. Yadav, who has been seen in close company of Bihar CM Nitish Kumar in the recent past, said Lalu Prasads affection for his family cost the party most and the party (RJD) would not have staged a comeback in the 2015 assembly polls,if RJD would not have stitched an alliance with Kumars JD(U). It was because of Kumar that RJD came to power in 2015 in the state, he said while adding but the party supremo again chose to anoint his both sons as Deputy CM and minister in Nitish Kumar led Grand Alliance government ignoring senior party leaders. When Nitish Kumar parted his ways, RJD chief again foisted his son Tejashwi and wife Rabri Devi as LOP in lower and upper house respectively.
