Twenty-eight validly nominated candidates will compete for 21 seats spanning six contested subsectors in the 2025 Election Committee Subsector (ECSS) By-elections, due to be held on September 7, the Registration & Electoral Office (REO) said today.

This follows an announcement yesterday by the Candidate Eligibility Review Committee that 100 nominations for the ECSS By-elections are valid, the REO explained.

The six contested subsectors are as follows: Commercial (third); Architectural, surveying, planning & landscape; Technology & innovation; Labour; Representatives of members of Area Committees, District Fight Crime Committees, and District Fire Safety Committees of Hong Kong & Kowloon; and Representatives of members of Area Committees, District Fight Crime Committees, and District Fire Safety Committees of the New Territories.

Five ordinary polling stations will be set up on the polling day. The polling hours will be 9am to 6pm.

In addition to the six contested subsectors, 72 candidates are returned in 22 uncontested subsectors. The nomination of one candidate for the Heung Yee Kuk subsector is invalid due to his death during the nomination period.

The REO added that the Electoral Affairs Commission will hold a briefing session for candidates on August 18 to familiarise them with electoral arrangements and regulations, with a view to ensuring that the by-elections are conducted in an open, fair and honest manner.
