LV= chief executive Richard Rowney is to leave the business after 13 years, the provider has announced.
Rowney will also leave his board position when he departs on 31 December, the savings, investment and protection provider said.
Interim chairman Alan Cook will assume executive chair responsibilities while the search for a successor is taking place.
Cook said: "Richard Rowney has served LV='s members, customers and staff with great distinction over the last decade and I thank him for all he has achieved.
"As managing director life & pensions he turned LV= into one of the UK's leading specialist retirement and protection providers. Most recently as chief executive he led the sale of LV='s general insurance business and the process to convert from a friendly society to a company limited by guarantee.
"The board and Richard have agreed that the time is right for him to step down. The process to appoint a new chief executive is now underway and we expect to conclude this before the end of the year."
Rowneyadded: "After 13 memorable years with LV= and the successful sale of our general insurance business to Allianz, now felt like the appropriate time to step aside and seek a new opportunity outside of the society.
"Our members continue to enjoy the benefits of being part of a strong and successful mutual organisation and I look back with pride at the strong and trusted brand that our people have worked so passionately to create."
