Ireland is set to bid to stage the 2023 Rugby World Cup with the bid to be unveiled in Armagh on Friday.
The IRFU will join with the Northern Ireland Executive and Irish government to outline their joint bid.
An Irish bid would use both traditional rugby stadia, such as the Aviva Stadium in Dublin and Thomond Park in Limerick, while also hoping to use Gaelic football venues such as Croke Park, which hosted rugby internationals during the renovation of Lansdowne Road.
As far back as May, Ireland coach Joe Schmidt showed his support for the idea, likening it to the 2011 World Cup hosted in his native New Zealand.
“You have got the same population and the same kind of energy around sporting occasions and I think you have got the stadia,” he said.
Ireland has never hosted a Rugby World Cup on its own, however the 1991 edition of the competition featured games in both Belfast and Dublin, as did the 1999 tournament, along with Limerick.
Next year’s World Cup will take place in England before the 2019 edition that is to be hosted by Japan.
Among the other possibilities for the 2023 World Cup, Agustin Pichot has already expressed his intention to bring the competition to Argentina, while South Africa and Italy are also believed to be interested in hosting the tournament.
