Prudential chief executive UK & Europe Jackie Hunt has exited the provider with immediate effect.
John Foley has been named as her interim successor.
Foley, currently group investment director, will fill the role alongside his current duties until a permanent successor is announced in due course, the company said in a note to the stock exchange.
Group chief executive Mike Wells said: “I would like to thank Jackie for the contribution she has made during a period of radical change in the UK marketplace.
“She leaves our UK life business in a strong position to continue to meet our customers’ long-term savings and retirement needs while delivering valuable returns for our shareholders. I am also delighted that we have someone with the experience and expertise of John Foley to take the business forward until a permanent successor is appointed.”
Chairman Paul Manduca added: “Jackie has been an important asset to the group during her time at Prudential, navigating our UK business through a time of significant change. The business is in good shape, and on behalf of the board I would like to wish her well for the future.”
Hunt joined the provider from rival Standard Life two years ago.
Before joining Standard Life in 2009, Hunt held a number of senior leadership roles within the UK insurance industry, first at Royal & Sun Alliance and then at Aviva.
