GAM has hired the FCA's Natalie Baylis as head of compliance while the firm's general counsel Dirk Spiegel is leaving "to pursue other opportunities".
Baylis will join the firm in June in the newly created role and will become a member of the firm's management board, subject to regulatory approval.

Baylis started her career at the FCA in 2006 in its general counsel division, working on a variety of regulatory issues.
GAM's chief executive Alexander Friedman commented: "The newly created role of the group head of compliance underlines the importance of this function to the group, and Natalie's extensive experience will ensure GAM maintains compliance with best practices in the changing regulatory environment."
Meanwhile Spiegel is leaving after four years with the firm with immediate effect meaning he will no longer serve on the board.
Prior to joining GFAM in October 2013, he was general counsel and a member of the executive board at Schroder Investment Management.
GAM's US general counsel Kenneth Dursht will become interim general counsel while the firm searches for a successor.
Friedman said: "Dirk has made very important contributions to GAM as general counsel for continental Europe and then as group general counsel.
