UK Parliament has published a letter from the FCA describing how it decides whether an informant is treated as a whistleblower.  The FCA states that each case is determined in its own unique issues, with factors considered by the FCA including: (i) who the individual is; (ii) the individual’s relationship to the regulated firm; (iii) , the source and nature of the information provided; and (iv) whether the individual wishes their identity or their engagement with the FCA to remain confidential.  The letter goes on to explain that all information which whistleblowers ask to be used in confidence is treated as such and confirms that whistleblowers are told that that their identities, and the information they provide, will remain confidential unless they their permission to disclose it is given.
