Fievet, who has been head of wealth management UK and Europe, has decided to leave after five years in senior management roles.

Henry Fischel-Bock is to replace Fievet and joins the wealth and investment management executive committee immediately. He has spent 30-years in the industry and joined Barclays in February 2010 from International Planning Group, a client advisory firm in Miami. It is understood that Fievet and Fischel-Bock will work closely to ensure a smooth transition.

Semaya, meanwhile, departs after starting his career at Barclays in 2004, leading and growing Barclays Global Investors Japan. In 2006 he was appointed chief executive officer for BGI EMEA and Asia ex-Japan. Semaya joined the wealth and investment management business – then called Barclays Wealth - in 2009, leading its private banking business in the UK and Ireland until last year.
