India’s former Prime Minister Manmohan Singh, widely regarded as the architect of India’s economic reform program and a landmark nuclear deal with the United States, has died. He was 92. The hospital said Singh was admitted to New Delhi’s All India Institute of Medical Sciences late Thursday after his health deteriorated due to “sudden loss of consciousness at home.". He was “being treated for age-related medical conditions,” the statement added. A mild-mannered technocrat, Singh became one of India’s longest-serving prime ministers for 10 years and earned a reputation as a man of great personal integrity. But his sterling image was tainted by allegations of corruption against his ministers.
