Tell us
If you think a figure, date or rule on this site is wrong or out of date, please contact us with the page and, if you can, the source that shows the correct position. Serving officers often see changes before they're published, and we welcome that help.
What we do
We check the claim against the primary source, usually within a few days. If we got it wrong, we fix the data file (which updates every page using it), update the page's "last updated" date, and for material errors add a short note on the page saying what changed.
What we can't do
We can't publish figures we can't source. If something has been agreed but not yet published, we'll describe it as reported and update it when the official version appears.
