Ms Johnson said: “Anne will assume responsibility for Fidelity International at an important time in its near-50 year history.
“Our ambitions to broaden and deepen our relationship with our clients; innovate in product development and solutions design; and to continue to develop our investment platform and workplace investing businesses have never been greater. I am very confident in Anne’s abilities to lead the company in this exciting period of future development and growth.”

M&G Prudential announced changes to its senior leadership team on Friday in preparation for its planned demerger from Prudential plc. M&G Prudential was formed in 2017 through the combination of M&G Investments and Prudential's UK & Europe life business.
The company said the changes reflected the growing integration of the business units over the past year and will prepare M&G Prudential to operate as an "independent business."
In a Stock Exchange announcement, M&G said Anne Richards was resigning from her role and from the board of Prudential plc effective from 10 August 2018. Clare Bousfield, currently chief executive of Prudential UK, will become chief financial officer of M&G Prudential.
