Former Labour leader Joan Burton says passing Budget 2017 will be the first test for the new government.
Earlier the new Labour leader Brendan Howlin said the Fine Gael led minority administration is 'intrinsically unstable'.
Ms. Burton was replaced by Brendan Howlin as Labour party leader last Friday following her resignation of the position.
Dublin West TD Joan Burton said: "The real cutting point is going to be the budget. Because at that point you have to cut to the chase because at the end of the day the country has to have a budget, so there's a series of decisions that can't be avoided."
