Dominic Morgan has left his role as MD at FTI after more than nine years with the agency.
Morgan, who reported to senior MD Sue Brown and worked on the firm’s extensive property portfolio, is understood to have left last week.
A spokesman for FTI declined to comment further on the departure, stating: "It is company policy not to comment on personnel issues."
Dominic Morgan joined FTI having previously worked with Brown at Tamesis, which was bought by Financial Dynamics (FD) before FD was acquired by FTI in 2006.
He also worked with Tamesis co-founder and former FTI corporate comms chairman Tony Danaher, who left the agency in recent months.
It is thought that Morgan, who could not be reached, will not be replaced in the role.
