Here is the moment Leo Varadkar stumbled over a question on illegal drug consumption on last night's Virgin Media TV debate.
Both Varadkar and Martin did their best to convince voters that they should be the next Taoiseach in the landmark debate.
The two leaders were cagey and there were no killer blows landed, meaning the 2020 general election race is still wide open.
But one of the most controversial moments of last night's show was a question on illegal drugs.
Host Pat Kenny first addressed Fianna Fail leader Micheal Martin, asking him if he had ever consumed illegal drugs "in any shape or form".
Mr Martin responded by saying that he never had, but Fine Gael leader Varadkar seemed to struggle when pressed further.
The Taoiseach said: "I answered that question in a Hot Press interview about 12 or 13 years ago and I answered it truthfully."
After an excruciating pause, Pat Kenny repeated his question, asking for a definitive answer.
Eventually the Taoiseach confirmed that he had, but stressed that it was "obviously a long time ago".
In the Hot Press interview in May 2010, Varadkar admitted to smoking cannabis when he was in college.
And when asked if he had ever experimented with ecstasy or other illegal drugs, he told the music magazine: "Not since I've held elected office, anyway. I’ve been extremely law-abiding since I’ve been elected to politics."
However there was a mixed reaction to the question on social media, with one suggesting that the Taoiseach "should have just admitted it" at the first opportunity.
But others claimed that it was a "ridiculous" and "uncalled for" question.
Elsewhere it was the decision to exclude leader Mary Lou McDonald from the debate that dominated most of the fallout from last night's debate.
Sinn Fein have taken legal action over their absence from the show, as well as RTE’s two-man leaders’ debate the week after next.
Many viewers were unhappy with the decision, with one branding the arrangement "outrageous", while another said it was a "bit mad".
Another suggested that Sinn Fein's presence could have led to higher TV ratings and more public interest in the show.
