Professor Felice Lieh Mak is to resign as chairwoman of the English Schools Foundation at the end of March next year, six months before her three-year term ends. Lieh Mak, who has held the position since early 2004, said yesterday she would like to spend more time with her first grandchild, expected in a few weeks. She said her earlier departure would help the next chairman to get familiar with the post before board members start their terms in September.
