Voters are going to the polls in the Republic of Ireland's general election.
Polls opened at 07:00 local time and will close at 22:00.
Counting will begin on Sunday in all 39 constituencies. Newly elected TDs will gather on 20 February for the 33rd Dáil (Irish parliament).
A total of 160 representatives will be returned to the Dáil. The ceann comhairle, or speaker, is automatically re-elected.
In most situations, the speaker does not vote, so a government will need 80 TDs to hold a majority.

It is unlikely that any party will reach that number, so another coalition government is probable.
The election uses proportional representation with a single transferrable vote.

Traditionally, islanders have voted ahead of the rest of the country to ensure that bad weather does not hamper the return of ballot boxes to the mainland in time for the count, which will start on Sunday.
About 2,100 island residents were eligible to vote.
