The final debate of the 2025 Presidential Election campaign will kick off tonight on RTÉ's Prime Time.
The live broadcast will be presented by Miriam O'Callaghan and Sarah McInerney and begins at 9.35pm.
During the 2018 campaign, 885,000 viewers tuned in at some point during that Prime Time presidential debate.
In last year's General Election, there was a debate which featured ten party leaders.
Tonight's offering will have just two candidates: Independent Catherine Connolly and Fine Gael's Heather Humphreys.
The name of the Fianna Fáil candidate Jim Gavin will be on Friday's ballot paper but he has withdrawn from the contest.
Polls suggest there is a significant number of undecided voters, so tonight's debate is an opportunity for both candidates to capture that support.
Three opinion polls in succession have suggested that Ms Connolly has a commanding lead.
In 2018, there were six presidential election candidates in the field.
Last Thursday's Irish Times Ipsos B&A poll suggested that 49% of respondents did not feel represented by either candidate in the field.
The survey also indicated that 18% of voters were undecided, 12% would not vote and 6% would spoil their vote.
This election is now a straight shoot-out, and with only two days of campaigning remaining after tonight, this debate marks one of the last opportunities for the candidates to state their case.
Voters will go to the polls on Friday, with polling stations opening at 7am.
According to the Electoral Commission, the total number of "presidential electors" is 3,612,957.
The Prime Time Presidential Debate will be broadcast simultaneously at 9.35pm on RTÉ One, RTÉ News Channel and RTÉ Player, and will feature live Irish Sign Language interpretation for the Deaf and ISL community.
It will also be streamed live on the RTÉ One account on Instagram, Facebook, TikTok and X.
