Sources

Every figure published on this site has a named source, a licence, a retrieval date and a stated level of authority. All of them are listed here.

Sources in use

Data is republished under its respective licences, which require attribution. We do not republish official documents: links always point to the original, and of the manifesto text we keep only what is needed to search inside them and to quote passages.

The tier says how close a source is to the original. Almost everything here is tier 1 or 2. Tier 3 covers the little that no official source publishes in open form — the mixed group’s components and the party of a deputy who won a single-member district — taken from a reputable third party and checked against the official data. Until 1 August 2026 it also covered the names of the deputies elected overseas, today’s parliamentary groups and who replaced whom: the Chamber opened its data and those moved to tier 1. The tier is given on every entry and repeated wherever the figure appears. Since 3 August 2026 tier 3 also covers the press review — twelve outlets of which we publish the headline, the date and the link, and nothing else. That is not a data source and cannot be checked against anything official: it is reading matter, and no figure on this site comes from it.
