Uttar Pradesh MLA from Bulandshahr Virendra Singh Sirohi passed away early on Monday at a hospital in Delhi after a prolonged illness.
He was 73.
Uttar Pradesh Chief Minister Yogi Adityanath condoled the demise of Sirohi, describing it as an "irreparable loss to the society".
The BJP leader and former state minister was suffering from liver ailments and was hospitalised a fortnight ago, his son Digvijay Sirohi said.
"He was suffering from liver ailments and breathed his last around 3.30 am today," his son told PTI.
He said the body was brought to his home in Bulandshahr for last rights.
"I am distressed to hear the news of the demise of Virendra Singh Sirohi, MLA Bulandshahr Sadar. His departure is an irreparable loss to the society. I pray to Lord Ram to give him a place at his feet and provide support to the bereaved family to bear this painful sorrow," Adityanath tweeted.
Sirohi, representing Bulandshahr Sadar, was a three-time MLA.
He was first elected as MLA for the 13th UP Assembly in 1996, then in 2007 and last in 2017. He also served as Revenue Minister from 1997 till 2002 in the Mayawati-led state government.
