Singh was admitted to New Delhi’s All India Institute of Medical Sciences late Thursday after his health deteriorated due to a “sudden loss of consciousness at home,” the hospital said in a statement.
“Resuscitative measures were started immediately at home. He was brought to the Medical Emergency” at 8:06 pm, the hospital said, but “despite all efforts, he could not be revived and was declared dead at 9:51 pm.”
Singh was being treated for “age-related medical conditions,” the statement said, the AP reported.
A mild-mannered technocrat, Singh became one of India’s longest-serving prime ministers for 10 years and leader of the Congress Party in the Parliament’s Upper House, earning a reputation as a man of great personal integrity. He was chosen to fill the role in 2004 by Sonia Gandhi, the widow of assassinated Prime Minister Rajiv Gandhi.
Prime Minister Modi, who succeeded Singh in 2014, called him one of India’s “most distinguished leaders” who rose from humble origins and left “a strong imprint on our economic policy over the years.”
