What Tweede Kamer does

The Tweede Kamer der Staten-Generaal is the directly elected lower house of the bicameral parliament of the Kingdom of the Netherlands, constitutionally established in 1814 and headquartered at Postbus 20018, 2500 EA Den Haag. It comprises 150 elected representatives serving approximately 17.5 million Dutch citizens and exercises statutory authority over legislation, national budget approval (Rijksbegroting), and oversight of the Dutch cabinet and individual ministers. The institution preserves parliamentary heritage including the Erelijst van Gevallenen, a memorial honoring approximately 17,500 people who died for the Netherlands during 1940-1945.

Its core digital product portfolio centers on parliamentary transparency and citizen engagement. The primary asset is the Open Data Portaal (opendata.tweedekamer.nl), backed by a Gegevensmagazijn (Data Warehouse) that exposes more than 630,284 parliamentary documents via two APIs: an OData API delivering JSON-formatted searchable query responses, and a SyncFeed API delivering XML feeds based on Atom 1.0 for database synchronization. The portfolio also includes the official tweedekamer.nl information portal, Debat Direct (a livestream platform for plenary and committee debates), Kindervragenuur (an annual Children's Question Hour engaging primary school students with ministers), and Derde Kamer (a youth civic education site). International engagement includes joint hosting with the Eerste Kamer of the 2026 OSCE Parliamentary Assembly annual meeting in The Hague. The Open Data Portaal is fully compliant with the Dutch Digital Accessibility Act and EN 301 549/WCAG 2.1 standards.

The institution has no commercial revenue model; it is funded through the Dutch national government budget, with all public-facing services provided free of charge and without registration. Its two primary constituent segments are Dutch citizens and residents (including youth engaged through dedicated programs) and the Dutch government and ministers (who appear for debates, accountability sessions, and legislative consultation). The Tweede Kamer is led by Kamervoorzitter Thom van Campen, who presides over sessions and represents parliament externally.
