In recent months, some BJP allies have complained about party's handling of its allies.

Highlights JD(U) told BJP it needs to up its handling of "considerable resentment"

Nitish Kumar has been demanding centre to give special status for Bihar

Rashtriya Lok Samata Party asked BJP to give up its big brother attitude

Shiv Sena's Uddhav Thackeray took frequent swipes at the BJP for its approach towards its NDA allies. But he wasn't among the only one in the NDA to deliver a sharp message to the BJP. Just hours into the BJP's electoral losses in Thursday's by-elections, there were some discordant noises from Bihar as well. Chief Minister Nitish Kumar's Janata Dal United, which revived its alliance with the BJP after dumping the Rashtriya Janata Dal, or RJD, and the Congress less than a year back, was among those to speak out.Mr Kumar's JDU told the BJP that it needed to up its handling of the "considerable resentment" against the government across the country over a number of issues "the latest of these being the spiralling petrol and diesel prices". It also wanted the BJP to stop taking its alliance partners for granted."The NDA is a large coalition and we hope that (BJP president) Amit Shah, as the leader of the biggest partner, will take the initiative to communicate better with alliance partners," Mr KC Tyagi, the senior JDU leader and spokesman said after his party lost another prestige battle to the RJD run by Tejashwi Yadav.For a party that has rarely given its senior partner in the alliance advice, this was one of the strongest remarks to have come from Mr Kumar's party despite its "unhappiness" at the central government refusing to keep its promises to Bihar. One of them was the assurance that the BJP would accord Bihar special category status, which would let it access huge central funds and give tax breaks to industries.Another BJP ally from Bihar, the Rashtriya Lok Samata Party, or RLSP, was a lot more outspoken. It asked the BJP to give up its big brother attitude towards alliance and work on coordination within the NDA."It is no secret that discontent has been brewing among some sections of the NDA for quite some time... Mostly, it has been because of the big brotherly attitude shown by the BJP," the party headed by Union Minister Upendra Kushwaha, said in a statement."We hope that better sense will prevail over the BJP high command and they will sit together to formulate policies that can help strengthen the alliance in the state", it said.In recent months, some other BJP allies too have complained about the BJP's handling of its allies. In March, the Andhra Pradesh Chief Minister N Chandrababu Naidu's Telugu Desam Party had walked out of the NDA. And the BJP ally Shiv Sena has increasingly turned into the BJP's sharpest critic.

BJP lawmaker and journalist Chandan Mitra told NDTV that there was need for corrective steps because if there was a rift in the family, the "entire edifice of your political support could collapse"."There are rumblings in the BJP-JDU alliance and Mr Kumar has, rather late in life, started flip flopping lately.... And is leaping before he looks," he said, suggesting that Mr Kumar appeared to be out of his depths in the NDA alliance.
