Sri Lanka Local Government Election 2025: Numbers.lk Pre-election Poll Shows NPP Leading with Nearly Two-Thirds of National Vote

With Sri Lanka heading to the long-delayed local government elections on May 6, the pre-election survey by Numbers.lk shows a striking lead for the National People’s Power (NPP), placing the leftist coalition well ahead of its traditional rivals in national-level voting intentions.

These will be Sri Lanka’s first local government polls (except for special elections like Elpitiya PC) since 2018, after multiple postponements triggered by economic and administrative arguments. In August 2024, the Supreme Court ruled the delays unconstitutional, compelling the government to enact the Local Authorities Elections (Special Provisions) Act No. 1 of 2025 and reset the electoral calendar.

According to the Numbers.lk pre-election poll conducted between April 20 and May 2, the NPP holds 65% of the national vote share among likely voters. The Samagi Jana Balawegaya (SJB) trails with 11%, followed by the United National Party (UNP) at 8% and the Sri Lanka Podujana Peramuna (SLPP) at 5%. Smaller parties and independents make up the remaining 12%.

Sri Lanka’s Local Authorities Election System

Sri Lanka’s local government elections follow a mixed electoral model introduced in 2017, which combines ward-level races with proportional representation. Sixty percent of council seats are filled through first-past-the-post contests, where the candidate receiving the most votes in each ward is elected. The remaining 40% are allocated proportionally, based on each party’s total vote share within that local authority.

This system is designed to balance direct voter choice with overall party representation. However, unlike in most electoral models, the total number of seats in a local council is not strictly predetermined. Instead, the final council size is determined only after votes are counted.

Overhang seats: If a party secures more ward victories than its proportional vote share would justify, additional seats are added to maintain both proportional fairness and the integrity of the ward results.
Mandatory female representation: By law, women must make up at least 25% of each council. If this quota is not met through direct ward victories, supplementary seats could be added via the party lists to meet the requirement.

These structural provisions introduce a layer of variability that makes pre-election forecasting difficult and complicates post-election analysis. The final composition of each council—both in seat count and party balance—can only be confirmed after all votes are tallied and adjustments applied.
