Mr Steele joins from CCLA, the investment manager for the Church of England, and will manage the Sarasin Global Dividend and Global Higher Dividend funds alongside the company’s wider income team.
Current manager Darryl Lucas, who took over the portfolios following former manager Mark Whitehead’s departure this summer, is to exit the firm.
Sarasin’s other new recruit, Mr Mitchell - who also joins from CCLA - will assist in the management of a range of mandates, in particular the company’s UK equity mandates.
Meanwhile, global equities head Harry Talbot-Rice is to pass responsibility for the firm’s EquiSar unit trusts to co-manager Alex Hunter and chief investment officer Guy Monson.
The pair will manage the £187m in Irish-domiciled EquiSar funds, and will take responsibility for the £145m UK Oeic global EquiSar funds in due course.
Sarasin said in a statement: “[Mr Hunter’s] deep understanding of the investment process will continue to prove invaluable, complemented by [Mr Monson’s] longstanding history in thematic investment and the EquiSar family of funds.”
