Women and Leadership, co-authored by Julia Gillard and acclaimed development economist Dr Ngozi Okonjo-Iweala, combines research with interviews with some of the world’s extraordinary women leaders. It examines the influence of gender on women’s access to positions of leadership, the trajectory of their leadership and the circumstances in which it can come to an end. Julia talks to Jacqueline Maley about the radical shift required to close the gender gap, and her inspirational new book that she hopes will provide an action agenda for change.
