Northern Ireland First Minister Michelle O'Neill has not ruled out a run for the upcoming presidential election.
Asked if she was considering putting her name forward, Ms O'Neill said Sinn Féin is working its way through deliberations on putting forward a candidate.
Her comments come as Taoiseach Micheál Martin said he is not aware of any engagement with former SDLP leader Colum Eastwood over becoming the Fianna Fáil candidate for the presidency.
It has been reported that Mr Eastwood is considering a bid for Áras an Uachtaráin.
Asked to confirm if Mr Eastwood had been approached by the Fianna Fáil party, Mr Martin questioned the basis for the question, adding: "There's been no contact with me, there's been no engagement that I am aware of from the Fianna Fáil party and it hasn't been on the agenda at all."
Mr Martin said he was "surprised" to hear Mr Eastwood was considering a run but said "it's open to everybody to put themselves forward".
He said Mr Eastwood was a "very effective parliamentarian" but Fianna Fáil had not concluded on deliberations "at all".
Taoiseach Micheál Martin, Tánaiste Simon Harris and other Cabinet members were in Co Armagh today to attend the 29th plenary meeting of the North-South Ministerial Council.
The council was established by the Good Friday Agreement.
Deputy First Minister Emma Little-Pengelly said the GAA can "do a huge amount" with existing funding commitments for Casement Park.
She said the GAA should indicate what its contribution increase should be and added that it should "cut its coat according to its cloth".
Asked if the GAA should reconsider the plans for the west Belfast stadium development based on existing commitments for funding, Ms O'Neill said the stadium is now more expensive than if it had been built "a long time ago".

She said the delays were due to a "whole plague of problems" including planning and political issues.
She said the redevelopment would bring "major social and economic benefits".
Tánaiste Simon Harris said the recent UK funding announcement was a "huge step forward" for the project.
He said the Government stands ready to assist the project and warned against looking back to see the money was "squandered".
Tariffs key focus at North-South Ministerial Council meeting
Meanwhile, a key focus of the North South Ministerial Council was the impact of international tariffs on both economies, Ms O'Neill said.
Speaking at a press conference, Ms O’Neill said the summit provided leaders a chance to discuss opportunity for growth of the economies in Northern Ireland and Republic of Ireland.
Eighteen days out from the looming US tariff policy deadline, Mr Harris told reporters: "I was particularly pleased to see the focus we were having from a business and trade point of view."
Ms Little-Pengelly said the meeting was a "good opportunity" to discuss domestic issues and "geopolitical challenges".
Leaders also discussed gender-based violence, mother-and-baby homes, and connectivity on the island.
The Taoiseach said the meeting was "very cordial and constructive on a lot of issues".
He said there had been "significant focus on infrastructure projects", adding there was "ongoing room for co-operation" on renewable energy and grid infrastructure.
