Given a reference text about Former Indian Prime Minister Shri P.V Narasimha Rao, tell me when they were born, when they were Prime Minister and their most significant accomplishments in office

Pamulaparthi Venkata Narasimha Rao (28 June 1921 – 23 December 2004), popularly known as P. V. Narasimha Rao, was an Indian lawyer, statesman and politician who served as the 9th prime minister of India from 1991 to 1996. He is known for introducing various liberal reforms to India's economy. His ascendancy to the prime ministership was politically significant because he was the second holder of this office from a non-Hindi-speaking region and the first from South India (United Andhra Pradesh). He led an important administration, overseeing a major economic transformation and several home incidents affecting national security of India. Rao, who held the Industries portfolio, was personally responsible for the dismantling of the Licence Raj, as this came under the purview of the Ministry of Commerce and Industry, reversing the economic policies of Rajiv Gandhi's government

Shir P.V. Narsimha Rao was born 28 June 1921 and was the 9th Prime Minister of India from 1991 to 1996.
