Manipur chief minister N Biren Singh resigned on Sunday amid violence in the north-eastern state.

“It has been an honour to serve the people of Manipur so far,” Singh said in his resignation letter, which was handed over by him to state governor Ajay Kumar Bhalla at the Raj Bhavan.

He was accompanied by state BJP president A Sharda, BJP’s North East Manipur in-charge Sambit Patra, along with at least 19 MLAs.

“I am extremely grateful to the Central government for timely actions, interventions, developmental work and implementation of various projects for safeguarding the interest of every single Manipuri,” Singh’s resignation letter read.

The resignation comes a day after Singh asserted that his government had been making all efforts to restore peace in the strife-torn state.
