The Financial Institutions (Prudential Supervision) Regulations 1996

2.  Member States shall provide that all persons who work or who have worked for the competent authorities, as well as auditors and experts instructed by the competent authorities, shall be bound by the obligation of professional secrecy. Such secrecy implies that no confidential information which they may receive in the course of their duties may be divulged to any person or authority whatsoever, save in summary or aggregate form such that UCITS and management companies and depositaries (hereinafter referred to as undertakings contributing towards their business activity) cannot be individually identified, without prejudice to cases covered by criminal law.

Nevertheless, when an UCITS or an undertaking contributing towards its business activity has been declared bankrupt or is being compulsorily wound up, confidential information which does not concern third parties involved in rescue attempts may be divulged in civil or commercial proceedings.
