Tripura Chief Minister Biplab Kumar Deb has submitted his resignation to Governor SN Arya ahead of state polls next year.
Mr Deb made the announcement after meeting the governor at the Raj Bhavan on Saturday.
"Party wants me to work to strengthen the organisation," news agency PTI quoted Biplab Deb as saying.
The resignation follows reports of infighting within the BJP's state unit.
The BJP legislature party in Tripura, say reports, is to meet later today to elect its new leader.
