Authorities in India have declared a seven-day mourning period to honor Manmohan Singh as politicians and public paid tributes to the country’s former prime minister widely regarded as the architect of India’s economic reform program.

India’s former prime minister Manmohan Singh, who steered the country through sweeping reforms and paved the way for its emergence as a global economic powerhouse, has died. He was 92.

His financial reforms helped transform India into an emerging power. But his legacy was shadowed by allegations of corruption during his second term.
