Sai (77), a former two-time Lok Sabha MP and three-time MLA, had served as the party's state president in both Chhattisgarh and undivided Madhya Pradesh in the past.

In his resignation letter, Sai said his colleagues were hatching conspiracies and levelling false allegations to tarnish his image, which had left him deeply hurt.

"I am resigning from the primary membership of the BJP and all posts. Whatever responsibilities the party gave me I discharged them with full dedication. I express my gratitude to the party for it," he said.

Chhattisgarh Congress communication wing chief Sushil Anand Shukla said a "knowledgeable, polite and tolerant leader" like Sai leaving the party was a sign that the BJP was humiliating and neglecting tribal leaders.

"If he has left the party it means BJP is neglecting this very big class (tribals), which Sai could not tolerate,” Shukla said.
