What Is the Ethical Issue?
Anonymous sources are a cornerstone of investigative and public interest journalism. Whistleblowers, insiders, and individuals with knowledge of wrongdoing often cannot speak on the record without risking their jobs, liberty, or safety. The NUJ Code Clause 7 creates an ethical duty to protect the identity of sources who supply information in confidence. IPSO Editors’ Code Clause 14 affirms a moral obligation to protect confidential sources.
But anonymity also carries risks. It reduces accountability: a source who cannot be named also cannot be directly challenged. It can be manipulated: a source may seek anonymity not to protect themselves, but to make allegations they would not make on the record. And it limits transparency: readers cannot fully assess the credibility of a story when they cannot assess the credibility of the source.
The ethical framework governing anonymous sources requires journalists to: grant anonymity only when genuinely necessary; agree the terms of engagement clearly and in writing where possible; corroborate anonymous claims before publication; maintain the right of reply to the subject of any allegations; and be transparent with readers about why anonymity was granted, even if the source cannot be named.
When This Matters in Practice
Whistleblower exposing financial fraud
A mid-level employee provides documents showing their employer is falsifying safety records. The employee faces termination and potential legal action if identified. Anonymity is appropriate: the public interest is high, the risk of retaliation is real, and corroboration (the documents) exists. The editor should know the source's identity for legal defence purposes.
Government source on policy
A civil servant provides detail of unpublished policy on background. This is standard Westminster reporting. The terms must be agreed at the outset ("on background", "on the record", "not for attribution"). Attribution should be as specific as possible without identifying the individual: "a senior Home Office official" rather than simply "a source".
Allegation against a named individual
A source claims a named businessman is engaged in financial irregularities. Single-source allegations against named individuals require rigorous corroboration before publication. The right of reply must be given before publication, even though the source is anonymous.
Source seeking anonymity for opinion
A professional contact wants to criticise their industry but does not want to be named. Consider whether anonymity is genuinely necessary or merely convenient. Opinion that would not be expressed on the record is often opinion that the source would not be prepared to defend publicly — a signal to weigh it carefully.
Red Flags
- ⚠A source seeking anonymity to make allegations they would not make on the record
- ⚠A single anonymous source as the sole basis for a serious allegation against a named individual
- ⚠No contemporaneous record of what terms of engagement were agreed with the source
- ⚠An anonymous source who also appears to have an axe to grind against the subject of the story
- ⚠Anonymity being granted as the default rather than after genuine consideration of whether it is necessary
- ⚠The source has provided information that cannot be corroborated or verified independently
- ⚠No right of reply has been given to the subject of the allegations before publication
- ⚠No explanation to readers of why the source is anonymous and why that anonymity is justified
- ⚠The journalist does not know or cannot verify the source's identity themselves
- ⚠The source is seeking payment for information provided anonymously

Protect Your Sources & Assess Risk
Use the Source Protection tool for guidance on secure communication and protecting source identity. Use the Risk Register to document the decision-making around anonymity grants and corroboration.
Common Mistakes
- ›Failing to agree terms before the source speaks: The terms of engagement must be agreed before information is provided. If a source volunteers information and then says "that was off the record", the post-hoc restriction is much harder to enforce ethically.
- ›Using "a source said" without any contextual attribution: "A source said" is almost meaningless to readers. "A serving Metropolitan Police officer who could face disciplinary action if named" gives readers the context they need to assess the information.
- ›Single-source serious allegations: The hallmark of poor editorial practice. A single anonymous source making a serious allegation against a named person needs corroboration before publication. Without it, the risk of defamation, inaccuracy, and ethical complaint is significant.
- ›Not informing the editor of the source's identity: In a legal challenge or IPSO complaint, the editor needs to be able to attest to the source's credibility. If the editor does not know who the source is, they cannot defend the story. The source's identity should be known to at least one senior editor on a strict need-to-know basis.
- ›Skipping the right of reply because the source is anonymous: Anonymity of the source does not remove the obligation to give the subject of allegations a fair opportunity to respond. These are separate requirements. Combine them: "Before publication, [subject] was informed of the allegations and given 48 hours to respond."
