Khor, who will be based in Singapore, starts his new role on 8 March and will join the group executive, reporting to Aviva group chief executive Mark Wilson. The appointment is still subject to regulatory approval. Simon Machell, who has undertaken a wide range of roles with Aviva in the UK and internationally, most recently as chief executive for higher growth markets, will leave Aviva at the end of February. Khor's previous roles at AIA included chief executive and managing director of the company's Malaysian business and regional executive responsible for a number of AIA's South East Asian markets. In November last year, AIA announced that it had appointed Bill Lisle, AIA's group chief distribution officer, to lead the integration of ING Malaysia with AIA's business in Malaysia, reporting to Ng Keng Hooi, regional chief executive.
