Chairman David Woods has been appointed as chief executive on an interim basis until a new chief executive is appointed.
The mutual says it is carefully considering the future for its investments in Park Row and Citadel Financial Services.
Park Row posted a deficit of £2.17m at the end of the first half of 2009. The UK distribution arm of Royal Liver is currently being investigated by the FSA as part of a review into its systems and controls.
Royal Liver and Park Row would not comment further on the future of Park Row or the FSA investigation.
Royal Liver says it is planning to simplify its structure and focus on core manufacturing brands, Progress and Caledonian Life, in a bid to cut costs.
Woods says: “The after-shocks of the unprecedented events in the financial markets in 2008 continue to impact on all our markets and I am proud of the way the Society has faced these challenges. We have taken bold and often difficult decisions to mitigate these circumstances.
“However, the continuing strength and quality of our operations can be seen in the commendable performance of our manufacturing brands, Progress and Caledonian Life. We have therefore decided to focus our efforts around these businesses, to simplify our Group structure, actively manage our capital position and find further ways to reduce expenditure.
“This process has already begun and we have completed a major IT outsourcing project and brought to an end, expensive door-to-door collections in the UK and, soon, Ireland. We are considering carefully the future for our investments in Park Row and Citadel Financial Services.
“Given these developments, the Board, in discussion with the chief executive, has decided that this is an appropriate time for a change of leadership to meet the new challenges facing the Society. Accordingly, Steve Burnett has elected to leave the business after a seven year period as chief executive.
“On behalf of the Society, I would like to thank Steve for the enormous contribution he has made to Royal Liver. It was Steve who was the architect of the refocusing and modernization of the Society that has given it a new lease of life. Thanks to Steve, we have had a strong focus on reducing expenditure and two fine financial services brands in Progress and Caledonian Life. Seven years is a good innings and Steve leaves with our best wishes for him and his family.”
