What Is the Public Interest Test?
The public interest test is the ethical and regulatory gate that UK journalists must pass before they can justify intrusion into privacy, use subterfuge, pay sources, or take other steps that would otherwise breach their codes of practice. It is not the same as “what interests the public” — celebrity gossip may generate millions of clicks while failing the test entirely.
The distinction matters because the codes of practice enforced by IPSO and IMPRESS allow departure from their normal rules onlywhen a genuine public interest can be demonstrated. “The readers want to know” is not a public interest. “This exposes a risk to public safety that readers need to know about to protect themselves” may well be.
The IPSO Editors’ Code states that public interest includes, but is not confined to: detecting or exposing crime or the threat of crime, or serious impropriety; protecting public health or safety; protecting the public from being misled by an action or statement of an individual or organisation; disclosing a person or organisation’s failure or likely failure to comply with any obligation to which they are subject; disclosing significant incompetence that affects the public; and raising or contributing to a matter of public debate including art and literature.
When This Matters in Practice
Investigating a local councillor's financial interests
A councillor votes on planning decisions that benefit a company they have a financial stake in. Public interest: protecting the public from being misled and disclosing failure to comply with legal obligations. The intrusion into their financial affairs is justified.
Undercover reporting in a care home
A journalist works as a care assistant to document systematic neglect. Public interest: protecting the public (vulnerable adults) and exposing serious impropriety. Subterfuge is justified only if no other method could capture evidence.
Doorstepping a MP over expenses
Following a refusal to respond to written questions, a journalist approaches an MP at their constituency surgery. Public interest: accountability of public officials and protecting the public from being misled about the use of public money.
Publishing leaked documents about a drugs trial
A pharmaceutical company is withholding safety data from regulators. Public interest: protecting public health and safety. The leaked documents, though confidential, can be used if the public interest clearly outweighs the confidentiality breach.
Red Flags: When the Test Is Likely to Fail
- ⚠The sole basis for the story is curiosity or entertainment value
- ⚠The subject is a private individual with no public role relevant to the story
- ⚠The information was obtained by hacking, interception, or unlawful access
- ⚠The story relies on a single unverified anonymous source with no corroboration
- ⚠Less intrusive means were available but not tried
- ⚠The intrusion extends to family members who have not entered public life
- ⚠The decision to claim public interest was made after the story was written, not before gathering
- ⚠The editor cannot articulate what specific harm to the public was prevented
- ⚠The same public interest goal could have been achieved without identifying the individual

Open Public Interest Test Builder →Common Mistakes
- ›Conflating audience interest with public interest: High click-through rates, viral potential, or reader curiosity do not constitute a public interest defence.
- ›Blanket public interest claims: Claiming public interest in a story about a politician's affairs without connecting the affair to their public duties (hypocrisy, abuse of office) will not withstand regulatory scrutiny.
- ›Post-publication documentation: Writing up the public interest rationale after the complaint arrives carries minimal evidential weight. Document before or immediately at the time of publication.
- ›Ignoring proportionality: Even where public interest exists, publishing more information than is necessary to serve that interest (e.g. identifying family members, publishing home addresses) breaches proportionality.
- ›Assuming public role = no privacy: Public figures retain privacy rights in areas unrelated to their public role. An MP's voting record is public; their medical treatment is not, unless it affects their public duties.
