Mr James Tan has stepped down as chief executive of Tokio Marine Life Insurance Singapore, a role he has held since 2016.

Unilever chief Paul Polman will be retiring after a decade at the helm of the consumer giant, after a failed plan to move the firm's headquarters from London to the Netherlands.
The Anglo-Dutch maker of brands like Marmite and Dove soap will be headed by Mr Alan Jope, now chief of its huge beauty and personal care department, from Jan 1.
Unilever chairman Marijn Dekkers said Mr Polman was an "exceptional business leader who has transformed Unilever, making it one of the best-performing companies in its sector, and one of the most admired businesses in the world".
Mr Polman, 62, tweeted: "It's been a great honour to lead this team for the past 10 years and together build a sustainable business that has made a difference to millions of lives."
He is due to retire as CEO on Dec 31 but will stay for six months working on the transition with his successor.
Mr Jope, 54, has been with Unilever since 1985.
