Former New Zealand PM Jacinda Ardern to write a book on leadership

Former New Zealand PM Jacinda Ardern on Friday announced she's writing a book, with the focus more on leadership than on politics. Ardern said she had no date for when the book will be published. "But I hope when it's done, it's the kind of book that would have made a difference to my 14-year-old self," Ardern wrote on Instagram.
