The acting Minister for Children has said Fine Gael and Fianna Fáil can work to form a Government - as long as they get a written agreement.
James Reilly, who lost his seat in the General Election, has said he understands that the current talks between the historically rival parties are constructive.
Fine Gael and Fianna Fáil will maintain contact over this weekend, with official negotiations due to resume on Monday.
Minister Reilly has said a written document must be agreed in order for any minority government to be viable: “But I mean, there is a lot more work to be done, and many a slip between cup and lip.
“I think ultimately, talks are going well, contacts are being maintained and I am given to understand to that they are being constructive.
“But I do believe we will need some sort of written document for it to have a sustainable future in terms of a Government that can work.”
Meanwhile a Sinn Féin MEP has said his party is not afraid of a second general election.
Matt Carthy who was his party's Director of Elections has said they will put forward a strong opposition if Fine Gael succeeds in forming a minority Government.
However Mr Carthy has said they are ready to go back to the polls if required: “if a Government is formed, well and good.
“We will make sure our team of TDs and whatever number of senators get elected put it up to that Government in terms of the big issues of the day.
“Such as health and housing, if these talks fail, Sinn Féin aren’t afraid of another election.”
