Rathbone Brothers chief executive Andy Pomfret is to retire on 28 February.
Pomfret, who has been with the firm since 1999 and chief executive since 2004, will be replaced by deputy chief executive Philip Howell.
Howell joins the board with immediate effect and will assume the chief executive role on 1 March.
Howell joined Rathbones in March this year and was formerly chief executive of Williams De Broe.
Pomfret says: “I have had a fascinating 14 years at Rathbones, initially as finance director and for the last nine years as chief executive. I am delighted we were able to recruit Philip earlier this year and have thoroughly enjoyed working with him.
“Having recruited my successor, I believe it is now time to use my experience as both a chief executive and a non-executive director to develop a plural career. I wish Philip and everyone at Rathbones well for the future.”
Chase de Vere head of communications Patrick Connolly says:“Obviously Pomfret is a long standing chief executive and when there is a change at the top that can often have an impact on how the company is run.
“That said, even though Howell is relatively new to the company you would think that it will be business as usual. It is a natural progression and it looks like it is something they have planned out.”
