McDermott will take up her new role in addition to existing duties as head of corporate affairs, brand and marketing, StanChart said.

StanChart's global head of financial crime, John Cusack, is also stepping down at the start of next year to move into a part-time consultancy role at the bank, a source familiar with the matter told Reuters.

The source said this was not related to the bank's U.S. deferred prosecution agreement (DPA) being extended until the end of December this year.
