Minister for Health Leo Varadkar has said he does not mind being "slapped down or scolded" by Taoiseach Enda Kenny over his comments on the Budget.
Mr Varadkar had said people would be €5 or €10 better off weekly after the Budget, prompting a rebuke from Mr Kenny that details of a Budget are not discussed before the Cabinet make their decisions collectively.
Speaking today, Mr Varadkar said: "I don't mind being slapped down or scolded.
"I'm a big boy and I'm willing to take a degree of criticism from time to time, but at the same time, you know this isn't about me; it's not about my dignity, it's not about my ego.
"It's about frontline staff and it's about patients, it's about our health services which affect all of us and I think everyone in Government needs to get behind our health service."
Both the Taoiseach and Mr Varadkar were speaking at a Fine Gael 'think-in' in Cork
The Taoiseach said there is a very clear rule in place for many years that details of a Budget are not discussed before the Cabinet make their decisions collectively.
He said it wanted to make it clear again that the Cabinet has not made decisions on the detail of the Budget and he said he wanted everyone to understand that.
The Taoiseach added that comments can lead to assumptions and views that the Cabinet have not been signed off on.
Mr Varadkar responded to reports that he apologised to the Taoiseach in connection with his remarks on the Budget.
He said: "No, that's not quite the case, the Taoiseach was very clear that he doesn't want ministers to be speculating about the details of the budget - and he's totally right about that.
"But at the same time, I'm the Minister for Health, I believe I have a responsibility to defend the health services, and I'm going to continue to do that.
"As well as that, I am very committed to health sector reform, but that has to happen in a way that is workable and deliverable, and I think the Taoiseach understands that very well."
Asked whether he regretted his comments that people would be better off by €5 or €10 in the Budget, Mr Varadkar said he did not want to speculate about the Budget.
Responding to comments made by Mr Varadkar yesterday, Minister for Finance Michael Noonan said Mr Varadkar was trying to communicate that there is very little scope in the Budget for tax relief.
He said Mr Varadkar's comments were illustrative rather than predictive of what might be in the Budget.
