Micheal Lehane of RTE News reports Fianna Fáil Leader Micheál Martin has said his party will guarantee the Government can continue throughout 2019 and an election may be held early in 2020.
Business as usual was not an option and there must be an ability to put the national interest above party interest.
He said that Ireland was in a period of heightened danger over the fears created by a hard Brexit and the risk of a no deal outcome had risen dramatically.
Circumstances had changed and everybody had a duty to respond, Mr Martin said.
The review of the Confidence and Supply Agreement had shown complacency at the heart of Government, he said, and in normal times an election would be the right thing for the country but these are not normal times.
The chaos in London must not be allowed spread to Ireland, he said.
