Miffed BJP ally Upendra Kushwaha quits NDA, to meet Rahul Gandhi

"It is unfortunate that the government's priority is not to work for the poor and oppressed, but to fix political opponents by hook or crook," Kushwaha said in the letter.

The RSLP chief also held a press conference here in which he announced he has quit the National Democratic Alliance. "I have left NDA, other options are open," he said.

Kushwaha also attacked Nitish Kumar, saying the Bihar chief minister was against him.

The RLSP chief is likely to meet Congress president Rahul Gandhi later in the day. The meeting could possibly result in RLSP joining hands with the Mahagathbandhan in Bihar that includes Lalu Prasad's Rashtriya Janata Dal (RJD) and the Congress.

On December 6, Kushwaha had declared a "war" on the ruling alliance. However, he had stopped short of announcing a break-up with the Bharatiya Janata Party (BJP)-led coalition.

Kushwaha had been sulking ever since the BJP and the Janata Dal (United), reportedly, reached an agreement that the two parties would contest 17 seats each in Bihar, where the total number of parliamentary constituencies are 40.

Under the arrangement, it was reported that RLSP was to be given two seats — one less than the number it had fought and won in the 2014 Lok Sabha elections.
