He leaves behind a legacy: Congress mourns former PM Manmohan Singh's death

In a statement, the Indin Congress said: "He leaves behind a legacy of economic reforms, political stability, and dedication to uplift the lives of every Indian."

"His tenure first as a technocrat and then as India’s Prime Minister will be remembered for economic prosperity with focus on social welfare, and strengthening of India’s position on the world map," the grand old party said.

"Known for his quiet but resilient leadership, he was a man of principle who made tough decisions with care, concern and a steadfast commitment to nothing but the country’s welfare above all else," the party said.

Congress Chief Mallikarjun Kharge said India lost a 'visionary statesman' with Singh's demise.

"With the passing of the Former Prime Minister, India has lost a visionary statesman, a leader of unimpeachable integrity, and an economist of unparalleled stature. His policy of Economic Liberalisation and Rights-based welfare paradigm profoundly transformed the lives of crores of Indians, virtually creating a Middle Class in India and lifting crores out of poverty," Kharge said.

Rahul Gandhi says Manmohan Singh was his mentor

Party leaders and MP Rahul Gandhi said Singh led India with immense wisdom and integrity.

"His humility and deep understanding of economics inspired the nation. My heartfelt condolences to Mrs. Kaur and the family," he said.

Rahul Gandhi said: "I have lost a mentor and guide. Millions of us who admired him will remember him with the utmost pride."

Priyanka Gandhi Vadra said: "Few people in politics inspire the kind of respect that Sardar Manmohan Singh ji did."

"His honesty will always be an inspiration for us and he will forever stand tall among those who truly love this country as someone who remained steadfast in his commitment to serve the nation despite being subjected to unfair and deeply personal attacks by his opponents," she said.

"He was genuinely egalitarian, wise, strong-willed and courageous until the end. A uniquely dignified and gentle man in the rough world of politics," Vadra said. 

Former Prime Minister Manmohan Singh, who is regarded as the architect of the country's economic reforms programme as the finance minister in the early 1990s, died at New Delhi's All India Institute of Medical Sciences (AIIMS) on Thursday. He was 92.

India's two-time prime minister and Congress leader was brought to the hospital's emergency department, around 8 PM after his health deteriorated. He was administered CPR (cardiopulmonary resuscitation), but efforts to revive him remained unsuccessful, an AIIMS statement said.

Manmohan Singh rose to prominence as the country's finance minister during the Congress regime headed by PV Narasimha Rao during 1991-96, for bringing sweeping reforms that transformed the economy.

As the two-term UPA Prime Minister, he stayed at the top post from 2004 to 2014 and served as a member of the Rajya Sabha till early this year.

He retired from the Rajya Sabha in April.
