Amid reports of strained ties between the Bharatiya Janata Paty (BJP) and Janata Dal (United) in Bihar, the opposition parties have targetted the ruling alliance saying, the situation had once again proved that the electorate had been cheated.

"Though it is an internal issue of these two parties, it cannot be denied that they came together to betray people of Bihar. This is why the public has to bear the brunt of political strain between these two parties," RJD spokesperson Manoj Jha told ANI.

Congress leader Tariq Anwar outlined JD (U)'s missing representation from the Union Cabinet to assert that everything doesn't seem right between the two parties.

"Nitish Kumar is teaching BJP a lesson. He refused its offer of giving one cabinet birth in Central cabinet to?JD (U) and later expanded the Bihar cabinet by completely sidelining the BJP legislators. This makes it evident that not everything is right between two alliance partners and in coming times Nitish Kumar can create problems for BJP. He has already hinted that he has other options", said Anwar.

Previously, RLSP leader Upendra Kushwaha had taken a dig at the JD (U)-BJP alliance, saying the saffron party must now be ready for a "second betrayal" at the hands of Nitish Kumar.

However,?JD (U) has refuted claims of having a strained relationship with BJP.

The?JD (U) on May 30 decided not to be a part of Prime Minister Modi's new cabinet, rejecting BJP's offer a single ministerial berth.

"BJP wanted only one person from the?JD (U) in the Cabinet. It would have been just symbolic participation. We informed them that we do not need the Cabinet berth," Chief Minister Kumar had said.

The?JD (U) chief, who later attended Modi's swearing-in ceremony on May 30, had said, "It is not a big issue. We are in the NDA and are not upset at all. We are working together. There is no confusion."

On Sunday, it was reported that BJP leaders skipped the yearly "iftar" hosted by JD (U). Similarly, no JD (U) leader was seen at the "iftar" hosted by Deputy Chief Minister Sushil Modi.

The "iftar" parties in Bihar have gained traction this year after?JD (U) refused to be a part of Union Cabinet. However, Nitish Kumar has repeatedly denied any misunderstanding between the NDA allies.

In the recently held Lok Sabha polls, PM Narendra Modi-led NDA made a clean sweep in the state, winning 39 of the 40 seats at stake.
