# List of parliamentary elections in Sri Lanka

Parliamentary elections have been held in Sri Lanka since the first in 1947, under three different constitutions: the Soulbury Constitution, the 1972 Constitution, and the currently enforced 1978 Constitution. Sixteen parliamentary elections have been held up to and including the 2020 election. The seventeenth is scheduled for 14 November 2024.
The current Parliament of Sri Lanka has 225 members elected for a five-year term. 196 members are elected from 22 multi-seat constituencies through an open list proportional representation with a 5% electoral threshold; voters can rank up to three candidates on the party list they vote for. The other 29 seats are elected from a national list, with list members appointed by party secretaries and seats allocated according to the island-wide proportional vote the party obtains.
Every proclamation dissolving parliament must be published in The Sri Lanka Gazette and must specify the nomination period and the date of the election. The first meeting of the new parliament must occur within three months of the previous parliament's dissolution.

## History

In 1833 the Colebrooke-Cameron Commission created the Legislative Council of Ceylon, the first step in representative government in British Ceylon. Initially this council consisted of 16 members which included the British Governor, the 5 appointed members of the Executive Council of Ceylon, 4 other government officials, and 6 appointed unofficial members. In 1889 the number of appointed unofficial members was increased to 8.
