All three Presidential Election candidates have said they would like to see a united Ireland in the future, when questioned while out on the campaign trail across the country.
Campaigning in the Presidential Election is continuing with the candidates pitching their electoral messages in Dublin and Cork.
Watch: Presidential Election candidates share views on a united Ireland
Fianna Fáil's presidential candidate Jim Gavin has said that as a constitutional republican, a united Ireland would be about "unification of people first and territory second".
Mr Gavin is on the election trail in west Dublin ahead of his official campaign launch in the city tomorrow.
He said he was very proud of the Constitution and what it speaks to about a united Ireland.
He added that the president could play a positive role, but that unification would be a matter for governments.
He said: "I believe in a united Ireland, but I also believe in what the Constitution speaks to in terms of a democratic, peaceful process."
He said if elected he would be active in the border counties and in the north of Ireland, "meeting communities, building on the great work of the one of the leaders that I admire the most, President McAleese, and the work that President McAleese did in the north in terms of building bridges between communities".
He said his role as president, if elected, would be to meet both communities in the north and to build on President McAleese's work, as well as forging new connections and repairing ones that might be broken.
Irish citizens in Northern Ireland should have vote in election - Humphreys
Meanwhile, presidential candidate Heather Humphreys has said she supports giving Irish citizens in Northern Ireland a vote in presidential elections.
Ms Humphreys, who is campaigning in Cork, has previously said she wants to see a united Ireland based on the Good Friday Agreement. But this must be done through building trust and demonstrating that this is an inclusive country, she said.
"I have spoken to many and they have said they would like a vote," she said on Irish citizens in Northern Ireland being permitted to vote in future Presidential Elections.
She said it would be a matter for the government of the day, and would require a referendum to extend the franchise.
"I know many people in Northern Ireland and I'd be fairly confident that I would get a fair share of their vote in Northern Ireland if they did have one," she said.
"I think that's something that we have to do, we have to work on it. It does involve a referendum to extend the franchise, and if we want a united Ireland at some stage down the road, I think it's important that Northern Ireland citizens should have a vote."
Always believed in a united Ireland - Connolly
While presidential candidate Catherine Connolly has told a Sinn Féin conference on Irish unity at Dublin City University (DCU) this afternoon that she has always believed in a united Ireland.
As far back as 2020 she has expressed this view but said it must happen by consent.
Ms Connolly told over 500 delegates present that it is a foregone conclusion that it is going to happen, and preparations are needed to show that this is a place that can embrace diversity.
She promised to give voice to the will of the Irish people on this issue if elected president.
She said that people must take courage in their hands and shape a new republic that provides housing and health services for its people.
Sinn Féin leader Mary Lou McDonald, who was present at the conference, said the time to plan for constitutional change is now and partition is on borrowed time.
She called on party members to knock on every door with optimism as they campaign for Ms Connolly.
