Joan Burton says the Labour party is "up for a fight" after the latest poll shows their support halved to just 4% support.
The Tánaiste says that the party will rebound from the poor result.
The Behaviour & Attitudes poll for the Sunday Times quizzed 1,026 voters on Monday and Tuesday of this week.
Joan Burton says she's ready for a fight in the last week of campaigning:
Fine Gael is up two points to 30%; Fianna Fáil is up 2% to 22%, and Sinn Fein falls 2 points to 15%.
Unaligned independents are unchanged at 10%.
Anti Austerity Alliance/People Before Profit, and the Independent Alliance are both on 5%.
The Greens, Renua and the Social Democrats are all on 3%, while the Workers Party is on 1%.
The poll has a 3% margin of error.
