Mark Bourke, chief executive of James Hay parent IFG Group, is leaving next April after 13 years with the firm.
Bourke will remain in his role until the end of April to facilitate an efficient transition period, after which he will move to his new position. The company has started the recruitment process for a new CEO.
IFG has made a number of key appointments in recent months, including John Cotter, as group finance director and David Edwards as chief risk officer.
IFG Group is the parent company of James Hay, Saunderson House and IFG Ireland.
IFG posted pre-tax profits of £2.6m for the first half of 2013 despite making a £4.6m provision for working capital in its international division.
The profit represents an increase of 13 per cent compared to £2.3m H1 2012.
In a statement, the firm says: “The board wishes to extend its thanks to Mark for the valuable contribution he has made to the group.”
