His appointment is subject to regulatory approval.
Alliance Trust Savings has named Ron Baxter, a former senior advisor at the UK's central bank and two of its regulators, chair of its board.
He will work with the firm's existing non-executive directors, Jonathan Anderson and Gregor Stewart.
Baxter spent nearly 12 years as a senior advisor in regulation, initially at the Financial Conduct Authority and latterly at the Prudential Regulatory Authority and Bank of England. He is currently a non-executive director of a consumer lending business.
“Ron’s experience with the regulator and his extensive knowledge of the industry will be invaluable as we deliver on our ambitious plans to grow assets under administration,” said Patrick Mill, Alliance Trust Savings chief executive. “Together with Jonathan and Gregor’s expertise and understanding of Alliance Trust Savings, the board complements the talent within our executive team and further cements our position as a leading platform for direct and advised clients.”
