Search members by name and house and get their party, constituency or peerage, gender, portrait and membership dates; look up any member by id; and search the bills currently before (or recently passed) Parliament with their long and short titles, originating and current house, and current stage (e.g. Report stage, Royal Assent). Ideal for civic-tech, news, political-research, transparency and government-monitoring apps. Open data from the UK Parliament.
