In the divided nation of Ireland, rugby union seems to offer a unique form of unity, with one national team representing two countries. This week's 'Rugby Reloaded' talks to Dr Liam O'Callaghan about the roots of Irish rugby and the reality behind its apparent national unity between North and South, and Catholics and Protestants.
Liam is the foremost historian of Irish rugby, the author of the essential work on the game in Ireland , Rugby in Munster: A Social and Cultural History, and works at Liverpool Hope University.
