Site Updates
MPData is a work in progress and is added to regularly. This page lists what has changed, most recent first, in plain terms rather than technical ones.
Last update: August 2026. This page covers changes to the site itself. The data behind it is refreshed every night — the Data Sources page shows exactly when each dataset was last brought in.

Fairer participation rates
improvedVoting and debate participation is now measured only against the business that took place while an MP was actually serving, so members who arrived or left mid-parliament are judged on the same basis as everyone else.
-
Votes counted against the right parliament
fixedLong-serving MPs were being measured against votes held before the 2024 election, making their attendance look worse than it was. Everyone is now compared over the current parliament only.

Former MPs
