Clare Independent TD Dr Michael Harty has said he does not intend to vote against the Government in key votes, such as Budgets or confidence motions.
Dr Harty said media reports that he has "withdrawn" support from the Government do not reflect his position.
Some reports said Dr Harty had pulled his support because he was not appointed as a junior minister by the Taoiseach.
Speaking to RTÉ News, Dr Harty said he was never offered, nor did he seek a junior ministerial position.
"I voted for Enda Kenny to be elected Taoiseach and to allow a Fine Gael minority Government to take office as that was the only viable government possible," he said.
"I never gave unqualified support to the Government so there is nothing to withdraw. I was then and remain an Independent TD."
The Clare-based GP said his position in relation to the Government was similar to the arrangement with Fianna Fáil.
"I will take each issue as it comes and decide. But I will not be voting to bring the Government down on crucial votes like the Budget, a confidence motion or a Cabinet reshuffle.
"Obviously, if there was some unforeseen cataclysmic event that threatened the Government I would have to consider that. But I intend to be responsible in how I vote."
