Rugby revolution: Is it right for sports stars to switch nationalities?

Available for over a year

A landmark new ruling in rugby union will allow players to switch allegiance to another country where they have ancestry. Is it a model other sports should follow in an increasingly globalised world, or does nation-swapping undermine the whole principle of international sport? We hear from former New Zealand fullback Charles Piutau who now hopes to play for Tonga, and the chief executive of World Rugby Alan Gilpin. We also find out how athletics has tightened its rules after years of controversial country switches. Panel: Sarah Mulkerrins, Dan Roan, Nesta McGregor, Chris Jones Producer: Sam Sheringham
