Former Union home minister Buta Singh, who remained in public service for a long time and served under four prime ministers, died at the All India Institute of Medical Sciences on Saturday morning. He was 86.
The senior Congress leader was in a coma since October last year, when he was admitted to AIIMS after he suffered a brain haemorrhage.
His family said Singh died around 7.10 am.
He will be cremated at the Lodhi Road crematorium later in the day.
Singh was an eight-time former MP and also served as the governor of Bihar.
President Ram Nath Kovind, Vice President M Venkaiah Naidu, Prime Minister Narendra Modi and former prime minister Manmohan Singh condoled his demise.
“In the passing of Shri Buta Singh, the country has lost one of the longest serving parliamentarians with rich administrative experience. He championed the cause of the oppressed and marginalized. Condolences to his family and supporters,” Kovind said in a tweet.
