A new opinion poll indicates that the gap between the coalition and an alternative government has grown.
The survey for the Sunday Independent shows that Fianna Fáil and the Progressive Democrats now enjoy a 10% margin over Fine Gael, Labour and the Greens.
Support for Fine Gael and Labour dropped one point each to 19 and 11% respectively.
The PDs and the Greens remain unchanged, with Sinn Féin down one point to 8%.
The poll was conducted last Thursday among one thousand people.
It shows a sharp drop in support for the inclusion of Sinn Féin in government and widespread scepticism about the party's response to the killing of Belfast man Robert McCartney.
