A head of compliance has left the firm and a chief risk officer has joined, stepping into a role that had previously been filled on an interim basis. The staff changes follow a number of senior departments in the last few months.

Robin Oliver, previously head of compliance for Europe, the Middle East and Africa at State Street, is now listed as inactive on the Financial Services Authority register of authorised persons. His public LinkedIn profile says he is an "independent compliance professional" and lists his status as "gardening leave" since February.
