Aviva Investors is searching for a new global head of compliance following the departure of the specialist who was brought in to oversee controls amid a regulatory probe that resulted in a £17.6 million fine for the asset manager last year.

The £290 billion fund manager, the funds arm of the UK insurer, confirmed in a statement that Robin Mitchell has left, 17 months after having joined in January 2015. His arrival was publicly cited by Aviva Investors among the changes it had made to tighten its ship after it identified failings in its fixed income dealing controls in May 2013.
