The question of a referendum on Irish unity is not a priority and does not “arise currently”, Simon Harris has said.
The Taoiseach said it was more important to work with the new UK government in supporting the powersharing institutions at Stormont.
Following the Westminster election, Sinn Féin emerged for the first time with the largest representation among Northern Ireland parties.
The republican party’s president, Mary Lou McDonald, took the opportunity to urge new British prime minister Keir Starmer to “embrace the right of Irish self-determination and constitutional change toward Irish reunification”.
However, Mr Starmer has previously stated that the issue of a united Ireland is not on his horizon.
Mr Harris told Sky News’ Sunday Morning With Trevor Phillips show that it was no surprise that there were differing views on the constitutional question.
He said: “The fact that we have different views on the constitutional future of Northern Ireland is not earth shattering news.
“And actually it’s because we have differences in relation to the constitutional question that we must find practical ways of working together.
“The Good Friday Agreement allows us both have those legitimate, differing aspirations, and there’s a structure in place to address that.
“For me, though, the focus and priority isn’t on a referendum, the focus on priority has to be on delivery.”
Mr Harris added: “People in Northern Ireland, people in Ireland, people in Britain, I believe, want to see real delivery when it comes to things like public services, their economy, prosperity, the economy in terms of how it impacts on their family and their businesses.
“And we have an opportunity now that the (Stormont) institutions are back up and running and I think we have people now in key leadership positions in Northern Ireland, in Dublin and in London who are fully committed to that.”
Mr Harris was asked if the prospect of a unity referendum had moved further away following Labour’s election win.
He said: “I just don’t think it arises currently.
“I think the most important thing here is as we have ministers back at their desks in Northern Ireland, and that they get on with the work, and that the British and Irish governments, as co-guarantors of the peace process, play our role in supporting that too.
“It’s absolutely appropriate to have legitimate constitutional aspiration, my party is called Fine Gael, the united Ireland Party.
“That’s my legitimate constitutional aspiration for the future of this island.
“It doesn’t arise today, though.
“What arises right now is a moment to reset Anglo-Irish relations after what was a very turbulent period of time, and I’m very excited about the opportunities that that presents.”
