Gulzarilal Nanda, Indian economist and politician, Prime Minister of India (born 1898)

Gulzarilal Nanda was an Indian politician and economist who specialised in labour issues. He was the Acting Prime Minister of India for two 13-day tenures following the deaths of Jawaharlal Nehru in 1964 and Lal Bahadur Shastri in 1966 respectively. Both his terms ended after the ruling Indian National Congress's parliamentary party elected a new prime minister. He was awarded the Bharat Ratna, India's highest civilian award, in 1997.

The prime minister of India is the head of government of the Republic of India. Executive authority is vested in the prime minister and his chosen Council of Ministers, despite the president of India being the nominal head of the executive. The prime minister has to be a member of one of the houses of bicameral Parliament of India, alongside heading the respective house. The prime minister and the cabinet are at all times responsible to the Lok Sabha.
