How we work
Our evidence standard
Facts are not left wing or right wing. But they can be incomplete, uncertain or misunderstood.
We prioritise primary sources such as official statistics, legislation, regulators, parliamentary publications and original research.
Where evidence is contested, we will say so.

Corrections log
When we get something wrong, we correct it publicly
Changing your mind when the evidence changes is not weakness. It is how better decisions are made.
