As per the sources, crack appeared between both the parties over seat sharing in the coming assembly polls. The JD-U wants more number of seats on the basis of its performance in the 2010 assembly polls, while the RJD cites its improved showing in the 2014 general elections.  

A close aide of RJD president Lalu Prasad said, “Bihar Chief Minister Nitish Kumar is in illusion over its political clout. He enjoys only 1.5 percent vote share in the state. Nitish also lost support among Mahadalits due to unceremonious exit of former chief minister Jitan Ram Manjhi. At the same time, Lalu Prasad enjoys huge support among the Muslim community.”

Interestingly, Lalu Prasad has been dominating Bihar politics riding on the strong Muslim-Yadav combination which accounts for around 30 percent of total populations in the state.

Earlier, Samajwadi Party general secretary Ram Gopal Yadav had said both the RJD and JDU should go to assembly polls as alliance partners as merger is not possible before the  elections due to technicalities.
