Prime Minister Narendra Modi on Friday paid tribute to Bhim Rao Ambedkar, a social reformer, economist, jurist and the architect of India's Constitution, on his birth anniversary.

He dedicated his life to the empowerment of the deprived and the exploited sections of society, Modi tweeted, posting an audio clip of his earlier remarks on Ambedkar's life.

Born in 1891 in a Dalit family in Maharashtra, Ambedkar rose from a humble background to become a leading voice of the marginalised people during the freedom struggle and is credited with introducing several social reforms.
