Sarah Brown talks to guests at Theirworld’s sixth International Women’s Day event, where women from all walks of life, with a few men dotted around, gathered to talk and share their experiences, contacts and ideas on how to unlock big change for girls and young women. We hear Dr Ngozi Okonjo-Iweala, former Nigerian finance minister and World Bank managing director, nearly moved to tears as she accepted our first Unlock Big Change award. We hear from other inspiring women, including Jo Brand, self-proclaimed ‘comic, writer, mother and super-model’; Amrit Kaur Lohia, musician and Theirworld Global Youth Ambassador; Sophie Walker, chief executive of the Young Women’s Trust; Yvette Cooper MP, chair of the Home Affairs Select Committee; Leena Nair, Chief HR Officer at Unilever; Rosemary Leith Berners-Lee, co-founder of the Web Foundation; Dr Anne-Marie Imafidon, mathematician and co-founder of the Stemettes, and not forgetting, of course, Theirworld’s very own Jamira Burley, who hosted the event.
