Deutsche Bank (DBKGn.DE) will sell Postbank (DPBGn.DE) but keep a pared back own-brand retail business in the overhaul plan currently favored by management, sources familiar with the internal discussions at Germany’s biggest lender said. Only two management board members support dumping all retail activities, with the other six favoring just selling Postbank, the sources told Reuters, speaking on condition of anonymity as the matter is not public.
