Edward Cumming-Bruce, co-head of UK investment banking at Dresdner Kleinwort Wasserstein (DrKW), has become the latest senior banker to leave the German-owned bank.

His decision to leave comes a month after the bank lost Manjit Boual, co-head of corporate finance, and has raised concerns about friction between DrKW's old guard and its new management team under Andrew Pisker and Karl Ralf Jung.
