Deutsch Bank has handed responsibility for pushing cooperation between its investment banking and wealth management operations in London to a former Credit Suisse banker, a year after giving another senior manager from the bank the same job in New York as it moves to replicate its Swiss rival’s cross-selling model.

Robert-Jan Kalff, who was responsible for coordinating cross-selling between Credit Suisse’s European investment banking and wealth management businesses, will form a similar unit in Deutsche Bank’s London office, designed to ensure closer ties between the two groups.
