Fine Gael has announced intentions to establish an independent forum designed to explore the legal and practical dimensions of Irish reunification.
The proposal follows recent statements by Taoiseach Micheal Martin regarding his own vision for unity with Northern Ireland.
Party leader Simon Harris, who is set to become taoiseach in November 2027 under the coalition's rotating agreement, indicated the body would be led by an independent chair appointed by the Irish government.
The proposed structure includes its own secretariat and budget, intended to operate for five years with a potential two-year extension.
Harris noted that security and defence policy differences between Dublin and Belfast would form part of the forum's examination.
Financial implications were highlighted as a central consideration, with estimates suggesting reunification costs could range from €3bn to €25bn depending on the scope of integration.
A separate calculation indicated that if Dublin assumed responsibility for Northern Ireland pensions and debt interest, total expenditure might reach between €13.6bn and €14.2bn.
The initiative comes as part of Fine Gael's broader blueprint on Irish unity, which was detailed at their recent ard fheis.
Both Fine Gael and Fianna Fáil currently hold seats in the Dáil, supported by Independent TDs in Dublin.
This development marks a significant shift in how the party approaches constitutional reform compared to previous years.
The forum would aim to provide a structured legal foundation for any future agreement between Ireland and the United Kingdom.
