Kleinwort Benson, one of the oldest names in British banking, is to be sold by Commerzbank to RHJ International, a Brussels-listed financial investor, for £225m in cash. The deal caps a long search by RHJ for a European banking business and reunites its CEO Leonhard Fischer with part of Dresdner Bank, where he worked for several years until 2003. RHJI said the acquisition of the private bank and investment manager would help it focus more on European financial services.
