This week's episode talks to award-winning journalist Carolyn Hitt about the BBC's 'Rugby Codebreakers' documentary on the Welsh rugby players, many of whom were black, who left Wales to play rugby league. We talk about the personal journey she went on as the presenter of the programme, the history of Welsh players 'going North', the differing responses of league and union fans, racism in rugby, and how things have changed over the past thirty years.
