Frequently asked questions

Ayes and Noes is a UK political accountability site that brings together MPs, parties, constituencies, Commons divisions, voting records, and related official parliamentary data. Source

Ayes and Noes uses official UK Parliament data sources, including the Members API and Commons Votes API, with attribution under the Open Parliament Licence v3.0. Source

Imports are currently run manually during development. The intended refresh pattern is daily for Commons divisions, weekly for current MPs, and monthly or on demand for profile snapshots. Source

A vote is an Aye or No recorded in a House of Commons division. Tellers are stored as Aye or No votes with a teller flag where the source identifies them. Source

Did not vote means there is no recorded Aye or No vote for that MP in that division. It does not by itself explain why the MP did not vote. Source

Voted against party means an MP's recorded vote differed from the majority recorded vote of their party in that division, based on the data imported for that vote. Source

Registered interests shown on MP profiles come from UK Parliament registered interests data exposed through the Members API profile snapshots. Source

Some Parliament API endpoints may omit fields, return incomplete historical records, or fail temporarily. Ayes and Noes shows available sourced data and avoids inferring unsupported facts. Source

Yes. MPs can change party or sit as independents. Current pages primarily use current party affiliation, while profile history uses imported biography data where available. Source

Constituency maps use boundary GeoJSON imported from the UK Parliament Members API and rendered locally as SVG paths. Source
