Well we've had a few big nights on The Frontline since we first came on air 17 months ago but tonight must be the biggest of all.
Micheál Martin, Enda Kenny, Eamon Gilmore, Gerry Adams and John Gormley will all be in our studio for the first ever five-way leaders'debate in front of a live audience.
The audience has been put together by the polling company Millward Brown Lansdowne as a representative group of undecided voters and Pat Kenny will be taking about six questions from them in all.
Those questions have been selected by an editorial panel comprising myself, Prof Michael Marsh of the Politics Department in Trinity College Dublin and Dr Jane Suiter of the Politics Department in UCC.
We'll be trying to hit most of the big issues and to get the politicians to actually answer the question they're asked. Pat's role will obviously be far more restrained than usual but he won't be completely absent from the question and answer process either.
We won't be reading out viewer comments on the programme tonight but do post your comment in the box below. Many apologies that we didn't get last week's comments up yet. I'm afraid it's been something of a hectic week but we will post your comments to this blog tonight. Enjoy the programme.
