Kolkata: Matriarch of the Matua community, Binapani Devi, popularly known as 'Boro Ma', passed away at a state-run hospital on Tuesday evening after a prolonged illness, a hospital official said.
Binapani Devi, 100, was on ventilator support at the SSKM Hospital here since Sunday and breathed her last at 8.52 pm.
Prime Minister Narendra Modi, West Bengal Governor Keshari Nath Tripathi and Chief Minister Mamata Banerjee condoled the death of the matriarch of the Matuas, a scheduled caste community and significant political force in the state.
Boro Ma was suffering from high fever, Chronic Obstructive Pulmonary Disease (COPD) and mild diabetes, the official said.
"She was in an 'extremely critical' condition, since last night. Her fever turned to pneumonia. Her lungs were infected. We tried our level best. Age was definitely a factor," he said.
Banerjee, who shared a very cordial relation with Boro Ma described her demise as "a personal loss".
"I have received support from her. It's a big loss to the Matua community. My condolences to her family and my brothers and sisters of the Matua community at this moment of grief," Banerjee told reporters at the SSKM.
"She will be accorded state-funeral with a gun salute. We are proud to have conferred the Banga Bibhusan on her. May her soul rest in peace," the chief minister said.
Banga Bibhusan is the highest civilian award of the West Bengal government.
Matua votes were considered a major factor in the Trinamool Congress' win in the 2011 and 2016 Assembly polls.
