Dr Manmohan Singh, the economist turned politician, served as prime minister of India for two terms, joining the likes of Jawaharlal Nehru, Indira Gandhi and Narendra Modi as one of India's longest-serving prime ministers. His two terms as Prime Minister from 2004 to 2009 and 2009 to 2014, were periods of high economic growth for India. However, his legacy extends to way before he held the highest executive office in the country. He has held almost all posts of significance to the economic welfare of the country, its industry and its people: from Governor of RBI to head of the Planning Commission and, crucially, as Finance Minister during an economic crisis, that saw India shed its Licence Raj and embrace market economics.
