It came after Sinn Féin TD Violet-Anne Wynne, who is a Protestant, took issue with the remarks.
“I am a Protestant and I am proud to be a representative for Sinn Féin. Changing facts is not the change that people voted for,” Ms Wynne said.
In his apology, Mr Varadkar said he was not aware of her religion.
“I did not make any remarks at all about Deputy Wynne personally,” he said.
“I was unaware of her religious affiliation and I stand corrected.
“I fully retract my remark and apologise for any offence caused.”
Speaking previously about a Sinn Féin ad campaign in the US print media this week, Mr Varadkar had told RTÉ’s News at One that the party was an “obstacle” to Irish unity.

Mr Varadkar described the problem as enormous . I m seeking explanations too, he told the Dáil (Irish parliament). I can understand how AstraZeneca might run into problems with supply for manufacturing or quality control.
