"Di Mu" Jayaratne,[3] was a Sri Lankan politician who was Prime Minister of Sri Lanka from 2010 to 2015. A founding member of the Sri Lanka Freedom Party, Jayaratne was first elected to parliament in 1970. He was sworn in as Prime Minister on 21 April 2010.[4]
D. M. Jayaratne was born on 4 June 1931. He was educated at Doluwa Maha Vidyalaya and at Zahira College in Gampola, a town just outside Kandy. Following the founding of the Sri Lanka Freedom Party in Kandy in 1951 by S. W. R. D. Bandaranaike, Jayaratne worked as a teacher at Doluwa Maha Vidyalaya. He later worked as Postmaster at Doluwa from 1960 to 1962.[5]
Jayaratne started his political career having been elected a member of the Village Council of Doluwa, where he later became the Chairman of the Village Council. He also become the President of the Kandy District Village Council Chairmen Association and a Member of the Federation of All Ceylon Village Council.
He first entered parliament following the 1970 general election, obtaining 14,463 votes as the Sri Lanka Freedom Party (SLFP) candidate in the Gampola electorate, and defeating W.P.B. Dissanayake of the United National Party (UNP).[6] He was subsequently defeated by Dissanayake in the 1977 election in which just 8 members of the SLFP were returned to parliament.[7] He was again re-elected to parliament in 1989 from the Kandy District under the new preferential voting system. He obtained 54,290 preferential votes, topping the SLFP list in the Kandy District.[5]
