World Rugby approves significant amendment to eligibility laws

The move is a potential game-changer for countries like Tonga, Fiji and Samoa

Former Ulster back Charles Piutau would be able to represent his native Tonga despite having played for New Zealand previously.

World Rugby has approved a significant amendment to eligibility laws that will permit players to switch countries from January.

It paves the way for a possible scenario like England internationals Billy and Mako Vunipola representing Tonga, as could ex-Ulster and New Zealand international full-back Charles Piutau, given their heritage with the island.
