Alliance Trust head of equities Ilario di Bon has left the firm.
Head of sustainable and responsible investment Peter Michaelis has been promoted to replace di Bon who is leaving to pursue other opportunities.
Simon Clements will take on responsibility for management of the Alliance Trust equity portfolio.
Both Clements and Michaelis joined the firm in 2012.
Alliance Trust chief executive Katherine Garrett-Cox says: “We wish Ilario well for the future. These changes will enable us to capitalise on the long track record and experience of the whole team. They will also allow us to promote an integrated and responsible investment strategy which we believe is a necessity, and no longer a choice, in today’s world.”
