January 28 (Reuters) - A prominent regional figure severed ties with Prime Minister Narendra Modi's Bharatiya Janata Party (BJP) on Sunday, months ahead of the country's general elections, and was expected to ally with the BJP once more.

The chief minister of the northern state of Bihar, Nitish Kumar, submitted his resignation to the state governor, according to sources in the local media.

Kumar disclosed to the news agency ANI that there were issues inside the alliance.

"I have instructed the governor to dissolve the state government and I have resigned as chief minister today." Not everything was fine, which is why this problem arose, according to Kumar.

The loss of Kumar hurts the opposition parties in India, who resolved to put aside their differences in order to unite under the name "INDIA" in order to challenge the BJP in the country's May general elections.

The main opposition Congress party is one of the 28 opposition parties that Kumar played a key role in putting together.

The BJP was afraid of the coalition, according to Congress leader Jairam Ramesh, and this "political drama had been created" to deflect.

The chief minister of West Bengal and leader of the Trinamool Congress party, Mamata Banerjee, declared last week that the alliance will fight Bengal on its own, causing significant instability already.

Likewise, the Aam Aadmi Party (AAP), which governs the northern state of Punjab and the national capital region of Delhi, declared that it will not form an alliance with the Congress party in Punjab.
