While the U.K. has longstanding whistleblower protection laws, in recent years there have been a number of significant developments affecting what good practice looks like in the context of company whistleblower programs, including new case law, regulation and guidance and, perhaps most importantly, increased regulatory and public scrutiny. In a guest article, Susannah Cogman, Hannah White, Amel Fenghour and Hanne Gundersrud of Herbert Smith Freehills explain the U.K. whistleblowing framework, discuss recent developments and future reform proposals, and examine good practice for whistleblowing programs. See “The Global Whistleblowing Legal Landscape and Best Practices in the U.S. and U.K.” (Feb. 19, 2020).
