US asset manager Payden & Rygel has appointed a 30-year buyside veteran to its London office, after he became the latest in a string of departures from the financial consultant Mercer.

Mark Stanley, who focused on fiduciary management at Mercer, has joined Payden & Rygel as a portfolio director with responsibility for business development and client relationship management in the UK and continental Europe, according to sources familiar with the situation.
