Sri Lanka is an island country in the Indian Ocean, situated near south-east India. Formerly known as Ceylon, Sri Lanka was occupied by the British East India Company during the 19th and 20th century. It was only in 1947 that Ceylon gained its independence from British Raj. Prior to independence, the post of the Prime Minister of Ceylon was created with D.S, Senanayake serving as the first Prime Minister of the nation. In 1972, Sri Lanka became a Republic, and thus the premiership was known as Prime Minister of Sri Lanka. In its initial days of functioning, Sri Lanka followed a Westminster-based political system wherein the Prime Minister served as the head of the government. He was the most powerful politician of the country. However, after the 1978 constitutional changes, Executive Presidency was adopted by the country according to which the President became the head of both the country and the government. The Prime Minister, on the other hand, served as the leader of the Cabinet and deputy of the President. Sri Lankan Prime Minister gained greater powers over appointment of his Cabinet of Minister after the 19th amendment that was instituted in 2015.
