Leo Vardkar told the Fine Gael Ard Fheis last week that a united Ireland was possible in his lifetime and no group can veto that.
Varadkar took critcism for his comments, in particular the timing of his comments.
The tensions within the loyalist community in Northern Ireland and the disruption and uneasiness within the DUP has caused some to criticise Varadkar.
However, the Tánaiste today said that there are people for whom it will “always be the wrong time” to talk about a united Ireland.
“For those people, including some in my own party, who are uncomfortable talking about unification, they will always be uncomfortable,” he continued.
He went on to say that there is no majority in Northern Ireland anymore, and said there is a growing number of people who want to discuss the possibility.
Northern Ireland Secretary Brandon Lewis said he was surprised by Leo Varadkar’s remarks and urged politicians to dial down the rhetoric, particularly as July 12th is emerging.
