NEW DELHI, July 26 (Xinhua) -- Chief Minister of India's eastern state of Bihar Nitish Kumar resigned from his post Wednesday, citing irreconcilable differences with the alliance partner, officials said.
The differences in the ruling coalition triggered over charges of corruption against state's deputy Chief Minister Tejashwi Prasad Yadav.
Yadav is son of Lalu Prasad Yadav, the head of Rashtriya Janata Dal (RJD).
"In the present circumstances it was becoming impossible for me to continue and work," Kumar told media outside governor's office in Patna, the capital city of Bihar, after submitting his resignation.
Governor Keshri Nath Tripathi has accepted Kumar's resignation.
Kumar decided to tender his resignation during party legislators' meeting on Wednesday.
The cracks in the coalition cropped up after India's premier investigating agency, Central Bureau of Investigation (CBI), lodged case against Yadav in land graft case. The agency has also filed case against Lalu Prasad Yadav and his wife Rabri Devi. Both senior Yadav and his wife have served as chief minister of the state.
Kumar's resignation has triggered political crisis in the state with no party having a majority in the 243-member Assembly (lawmaking body). Kumar's Janta Dal (United) has 71 seats, while RJD headed by Tejashwi's father Lalu Prasad, has 80 seats. The rightwing Bhartiya Janta Party (BJP), which is the opposition has 53 seats.
JDU and RJD combine branded as a game-changing Maha-gathbandhan (grand alliance) had stalled the BJP's emergence in Bihar. However, the alliance survived for only two years.
The senior Yadav has accused Kumar of hobnobbing with BJP and said his resignation was preplanned.
Meanwhile, Indian Prime Minister Narendra Modi congratulated Kumar for joining the fight against corruption, saying that 1.25 billion people of the country were welcoming and supporting honesty.
Analysts said BJP is likely to support Kumar in the new government formation.
