The number of stadia that would be required for the tournament has not yet been decided, but a key element will be to establish the number of locations and venues available before a feasibility study is undertaken to determine Ireland's overall capacity to host the tournament.

IRFU Chief Executive Philip Browne said, "The Rugby World Cup in New Zealand showed what a country of four million people could achieve in terms of attracting visitors and showcasing the potential of a country, so an overall Ireland bid is something that the government was keen to discuss with us.

"I think everybody is aware of the benefits from both a social and economic perspective that would come from hosting the third largest sporting event on the globe. We are at the early stages of examining the feasibility of a bid and part of this study is to determine the interest and support of Government and other relevant bodies."
