Campaigning in the referendum on the Eighth Amendment to the Constitution is entering its final day.
Polling stations in most of the country will open at 7am tomorrow but voters on a number of islands off the northwest and west coast will cast their ballots today.
Ballots will be cast on a total of 12 islands, with polling stations opening at different times during the day.
