Hargreaves Lansdown has appointed a former Barclays executive as its new chairman.
Deanna Oppenheimer will replace Mike Evans with effect from Wednesday 7 February after the latter's 12-year stint on the board of the FTSE 100 company.
Ms Oppenheimer has previously served as chief executive of Western Europe retail banking and chief executive of UK retail banking at Barclays.
She is currently the senior independent director of Tesco as well as a non-executive director of Whitbread and Axa.
Ms Oppenheimer said: "Hargreaves Lansdown is an innovative market leader for very good reasons and I was immediately attracted by the people, their values and the client first culture.
"Against a backdrop of a huge savings gap, political uncertainty and technological change, our challenge is to continue to make people's financial lives as easy as we can and help them to save and invest with confidence.
"I am excited by the opportunities ahead of us and am looking forward to playing my part in the HL story."
Ms Oppenheimer will cease two of her existing roles by mid-2018, with these announcements made by the respective boards at a later date.
Chris Barling, the senior independent director, will stand down from the Hargreaves Lansdown board at the same time as Mr Evans, and will be replaced by Shirley Garrood, the former chief operating officer of Henderson.
Mr Evans, a former chief operating officer of Skandia, joined the board of Hargreaves Lansdown in September 2006, shortly before the company's IPO in 2007.
Chris Hill, the chief executive of Hargreaves Lansdown, said: "We have benefitted from Mike's extensive experience and challenge as the group has grown into the market leading, client-focused, FTSE100 business it is today.
"On behalf of the board and indeed from everyone at HL, I would like to express my gratitude to Mike for his immense contribution to the group.
"We are delighted to announce Deanna's appointment. The knowledge and experience that she has built up throughout her executive and non-executive career, with its focus around customer engagement and technology, make her an ideal chair to lead the board into our next phase of growth."
