“Warm birthday wishes to our former Prime Minister Manmohan Singh. May he lead a long life filled with good health,” Modi said in a tweet.
Singh, who turned 85 on Tuesday, was the Prime Minister between 2004 and 2014 during the United Progressive Alliance (UPA) regime.
His political career began in 1991 when he was appointed as the country’s Finance Minister under late Prime Minister P. V. Narasimha Rao.
It was the same year during which he helped usher in “liberalisation and privatisation” to the Indian economy.
