one of sport's most iconic stars, siya kolisi made history by becoming the first black captain of south african test rugby, leading his team to world cup glory in 2019. for so long a symbol of white minority rule, the triumph of a diverse springbok side is a potent symbol of hope, progress and pride in the rainbow nation. the win capped a remarkable fairy tale for a man brought up amid poverty and violence in a township, but whose spirit and talent saw him rise to become one of the most inspirational figures in sport. now in a new autobiography, kolisi has revealed more about his life, and he agreed to speak to me from his home in south africa about what he wants to achieve now. this is his journey.
