Lalu Prasad Yadav’s party in Bihar is set to lose out on a state assembly election that could lead to the resignation of chief minister Nitish Kumar.
The JD(U) is set for a rout in the state assembly polls, in which Lalu has been the ruling party for a decade.
The JD(S) is the largest party in the Bihar Assembly.
The BJP is expected to get at least 10% of the vote, with the JD(B) and Congress expected to come third.
This would put the JD government on the back foot, which could see the party’s leaders resign in protest over the JD-B alliance.
The alliance between the two parties comes as the two political rivals are locked in a heated war over a new water supply scheme for the northern part of the state, a move that would help ease the pressure on the state government.
The two parties are expected to seek votes from their supporters in the northern state of Bihar, where Lalu is expected go on a three-day state visit this month.
The opposition Congress on Sunday claimed the government had been “failing” the northern and western parts of the country, with its water plan “the worst-ever”.
The party had earlier said that the government should have gone on a one-day visit in May this year.
