The Chartered Insurance Institute (CII) chief executive (CEO) Alan Vallance is to step down next year.
He will be leaving his position to become the CEO of the Institute of Chartered Accountants in England and Wales (ICAEW).
Vallance joined the CII in August 2022, having previously led the Royal Institute of British Architects. He is also a qualified Chartered accountant and long-standing Fellow of the ICAEW.
The CII said it will shortly begin a process to identify a replacement for Vallance.
Vallance said that leading the CII has "been a privilege".
He added: "Building and maintaining public trust in the insurance, financial planning and mortgage advice professions is essential to every economy around the world, and I am honoured to have had the opportunity to lead a Royal Charter body containing two pre-eminent global professional membership organisations - the CII and the Personal Finance Society (PFS).
"The decision to leave was not easy, but I am confident that the group is now in a much stronger position. The foundations we have built since 2022 are a solid base on which the Institute will continue to improve the way it serves its members, customers and the wider public for years to come."
CII Group board chair Dr Helen Phillips said: "The CII Group is sorry to see Alan leave, but we recognise his desire to take, what is, a unique opportunity to lead the Chartered body of his own profession.
"The CII Group board is grateful to Alan for the remarkable job he has done over his tenure, including leading the development and deployment of our new strategic plan. We look forward to identifying a successor to Alan soon to build on his strong legacy."
Vallance's resignation comes after a dispute with the PFS board. Yesterday (25 October), PFS revealed it had spent £850,000 on expert legal and financial advice as part of its ongoing board disputes with the CII.
There was a £1.4m increase in consulting costs and £850,000 of this was spent on expert legal and financial advice. The PFS said this was required due to the "unique circumstances triggered by the CII's desire to begin mediation from July 2022".
