Parliamentary elections are scheduled to be held in Sri Lanka before August 2025 according to the constitution. The president has the power under the constitution to hold elections two and half years after the previous elections, which took place in August 2020.

Electoral system

The Parliament has 225 members elected for a five-year term. 196 members are elected from 22 multi-seat constituencies through a proportional representation system where each party is allocated a number of seats from the quota for each constituency according to the proportion of the total vote that party obtains in the district. The other 29 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.
