The Parliament API provides each MP's total eligible votes and the number they participated in since the start of the current parliamentary session (July 2024). Participation percentage = votes cast ÷ votes eligible × 100.
This includes all divisions — procedural votes, Westminster Hall debates, and whipped votes — not just "meaningful" votes. Absence isn't necessarily poor performance: ministerial duties, illness, paired votes, and family emergencies all cause legitimate absences. Use the figure as a guide, not a verdict.
The Register of Members' Financial Interests Category 1 covers "Employment and earnings" — any paid work outside Parliament. MPs are required to declare employment, directorships, consultancies, media appearances, and any other paid roles.
Amounts are extracted from the declared interest text. RMFI entries do not always include precise amounts — some declare hourly rates or ranges rather than totals. Where a figure is unavailable, only the role is shown. All figures cover the current Parliament (July 2024–present).
Categories 3 (UK gifts and hospitality), 4 (visits outside the UK), and 5 (gifts from overseas sources) are grouped together on the Finances tab. These represent benefits received — not personal income — but must be declared to ensure transparency about who is providing MPs with hospitality, travel, and gifts.
Category 2 covers donations to fund an MP's parliamentary office and campaigning activities — not personal income. These are legally required to be declared both in the RMFI and (above a threshold) to the Electoral Commission.
Where the same donation appears in both registers, we show the Electoral Commission entry only and suppress the RMFI duplicate. We match on both the donation amount (within 2%) and the donor name — more robust than amount-only matching.
IPSA publishes annual budget and spend figures for each MP across four categories: staffing, office costs, accommodation, and travel. Figures shown are spend (amount actually claimed), not the budget allocation.
IPSA data covers the financial year April–March. 2024/25 data is shown where available. A small number of MPs (newly elected or by-election winners) may not yet have a full year of IPSA data.
| Data | Source | Cadence |
|---|---|---|
| MP list & status | Parliament API | Weekly (Mon) |
| Vote participation | Parliament API | Weekly (Mon) |
| RMFI interests & earnings | Parliament API | Weekly (Tue) |
| MP biography | Parliament API | Monthly (1st) |
| IPSA expenses | IPSA open data | Monthly (1st) |
| EC campaign donations | Electoral Commission | Monthly (1st) |
The RMFI also covers shareholdings (Category 7), property portfolios (Category 6), family members employed through parliamentary expenses (Category 9), and miscellaneous interests (Category 8). These are important transparency data points but don't carry £ values — showing a company name without context can mislead more than it informs. These categories are planned for a future release.
The Parliament Members API only returns the current register — historical snapshots are not available via the API. All RMFI data therefore covers the current Parliament (July 2024–present). IPSA expenses are available year-by-year and will be shown comparatively once 2025/26 data is published.
