Labour Party leader Eamon Gilmore has seen his party's popularity slashed by 25% - with Sinn Fein being one of the main beneficiaries, according to the latest Irish Independent/Millward Brown Lansdowne opinion poll.
The poll, conducted amid European turmoil this week, show how the government parties have both suffered from a year of implementing austerity measures -- with Labour hit hardest.
The new poll puts Fine Gael on 34pc, down 2pc since the general election, but Labour is on 15pc -- down four points in the same period.
Fianna Fail is stuck on 17pc, Sinn Fein is up seven to 17pc and Independents and other parties are up one point to 18pc.
Labour has borne the brunt of the hit from the unpopularity of the Government and Sinn Fein is breathing down its neck.
The honeymoon period enjoyed by the Coalition is long over, with two-thirds of voters dissatisfied with the performance of the Government.
The Coalition's satisfaction rating is at 29pc, with 65pc dissatisfied and 5pc 'don't knows'.
Taoiseach Enda Kenny's satisfaction rating stands at 42pc, with 52pc dissatisfied.
Fianna Fail leader Micheal Martin scores a 37pc satisfaction rating, with 50pc dissatisfied. Sinn Fein president Gerry Adams is failing to make an impact and gets 35pc satisfaction with 51pc dissatisfied.
But Mr Gilmore scores the worst results with a satisfaction rating of 33pc and a dissatisfaction level of 56pc.
Fine Gael remains by far the most popular party and has the support of one-in-three voters. Mr Kenny's party will be encouraged by this endorsement level in the face of the unpopularity of many of the austerity measures.
The Labour Party have also seen their support fall, but the party may feel a four-point fall to 15pc is acceptable, given the difficulties it has experienced in Government.
However, the pollsters identified a worrying trend for Labour: one-in-four of their voters from the 2011 General Election "has either gone to Sinn Fein or Independents".
"Labour is currently the most vulnerable of the major parties to such losses," Millward Brown Lansdowne concluded.
