Naomi, "Correct Mistakes" is in the same guidelines I referred to in the other thread. I'll suggest again, very few publishers have, let alone publish, similar standards and guidelines and ask to be held accountable to them. I'll ask again, where do you prefer to get your news of UK politics from?

Correcting Mistakes
3.3.28 We should normally acknowledge serious factual errors and correct such mistakes quickly, clearly and appropriately. Inaccuracy may lead to a complaint of unfairness. An effective way of correcting a serious factual error is saying what was wrong as well as putting it right.
Mandatory Referral
Where we believe we have broadcast a defamatory inaccuracy, Programme Legal Advice must be consulted.
Mistakes in on-demand and online content
Where mistakes in our on-demand content, which is available online after broadcast, are unlikely to be a serious breach of editorial standards, a correction should be published on that platform, so that it is visible before the output is played. Such on-demand content does not then normally need to be changed or revoked.
Where mistakes to our on-demand content are likely to be considered a serious breach of editorial standards, the content must be corrected and the mistake acknowledged, or in exceptional cases removed. We need to be transparent about any changes made, unless there are editorial or legal reasons not to do so.
In online text content, any mistake that alters the editorial meaning should normally be corrected and we should be transparent about what was wrong.
