Fianna Fáil leader Mícheál Martin has warned that Ireland is not adequately prepared for a no-deal Brexit.
He warned that Brexit is "the severest threat in over a decade to Irish society".
Speaking to reporters at Leinster House this afternoon ahead of his party's Ard Fheis, he said: "I think in terms of a no-deal Brexit, I don't think we are prepared."
"Certainly there is growing anxiety in the agri sector and the beef sector about what will happen if there is a no-deal Brexit."
"So I don't think we are adequately prepared for a no-deal Brexit," he said.
He claimed the Government had the view for a long time that we would not be where we are at the moment and a deal would be secured before Christmas.
He added: "It began to dawn that that prospect of a no-deal Brexit was a very real one, very late in the day."
He welcomed today's omnibus legislation and said his party will help out in any way it can.
He said the State aid for the agricultural industry is a very real and concrete issue that needs to be ironed out in advance of a no deal.
He said that there is no clear explanation, even though he has "asked the Taoiseach about six times in [the] Dáil", about what will happen on the border after 29 March if there is a no-deal Brexit.
He defended his party's decision to remain in the Confidence and Supply arrangement.
The Cork South Central TD said: "The political parties who were opposing us and Sinn Féin who were calling for a general election and for me to pull the plug, we would not be in a position to enact this legislation if I and the party did not take the position we took before Christmas with the Confidence and Supply.
"There is a lot of hot air out there from some quarters about preparing for Brexit and being ready for Brexit.
"The reality is that, again, Fianna Fáil had to take the hard decision before Christmas and, in my view, the correct decision to continue with Confidence and Supply, give the Government space in terms of the negotiations around Brexit but also to prepare for any eventualities."
"Brexit is probably the severest threat in over a decade to Irish society and it fundamentally changes the economic relationships between Ireland and Britain and Ireland and the EU for the first time in 50 years."
Asked if he is committed to the passage of a fourth Budget, he said: "We are committed to facilitating a budget.
"I said last December that we were committed to facilitating a further Budget and we were giving the Government further space throughout 2019 and that remains the position," he said.
Asked if he is also frustrated with the Confidence and Supply deal, he said that he is frustrated with "the inability of this Government to deliver".
