For each MP and each party/kraj:
- Účast na hlasování — share of votes the MP attended
- Rebelita — how often the MP votes against their own parliamentary club
- Vládnost — how often the MP votes in line with the government coalition
- Opravy hlasování — number of corrected ("oops") votes
- Ideologické pozice (WPCA) — 2D map of MPs based on voting patterns
Data
Analysis outputs are fetched from michalskop/cz-psp-data-2025-202x via raw GitHub URLs. The data repo runs a nightly GitHub Action that recomputes all analyses from official Poslanecká sněmovna open data.
The site uses Next.js ISR — pages are statically generated at build time and revalidated every hour.
Before adding or copying a vote dashboard, follow the incident lessons and release
checks in Vote dashboard performance.
