Brooksbank and Feather, who are the chairman and managing director of Feather Brooksbank respectively, will continue in their roles.
Aegis also plans to open a Manchester office for its search agency iProspect to complement Carat Manchester's strong digital offering.
In July, Aegis Media acquired a majority stake in MediaVest Manchester, which has since rebranded as Carat Manchester. A spokeswoman for Aegis Media said there would be no redundancies or changes in management as a result of the rebrand.
