New Delhi, June 24 (PTI): Playing the Dalit card, Jitan Ram Manjhi today sought the community's vote in the upcoming Assembly polls while referring to his "insult" by chief minister Nitish Kumar.

Manjhi, who belongs to the community, said all 22 Dalit castes in the state should join hands if they wanted to benefit politically and accused his mentor-turned-adversary Nitish of dividing them by coining a separate Mahadalit category for "political reasons".

Addressing a convention of his newly launched Hindustani Awam Morcha Secular, he dubbed the alliance between Nitish and his one-time rival Lalu Prasad as an "unholy alliance" and said it must be rooted out.

Though Manjhi remained silent on his alliance with BJP in his speech, a political resolution passed by the convention praised the development work of the Narendra Modi government.

"I urge the scheduled castes and tribes to come together. They are 16 per cent of the population. They must break the caste barrier and forge ahead together for political benefits. "I came from a deprived community and poor family. Nitish Kumar made me chief minister thinking I would be a rubber stamp. When I began applying my mind, he forced me out. It was an insult," he said referring to his forced removal from the chief minister's chair.

Bihar has a small SC/ST population and Nitish had succeeded in weaning away a big chunk of the SC community in previous elections by showering them with additional sops by clubbing them together as Mahadalit.

He left out only one caste, Dushadh (Paswan), which has been a traditional supporter of LJP chief Ram Vilas Paswan. Manjhi during his tenure brought Paswans under the Mahadalit category as well.
