A new opinion poll indicates that a large majority of voters in the Republic are opposed to a coalition including Sinn Féin.
A number of motions up for debate today at the party's Ard Fheis urge the party not to enter any such government.
Only 20% of those questoned for the Sunday Business Post survey said they would find the idea acceptable, with 69% saying they were opposed to it.
72% of people said the Government should insist on a signal from the IRA, such as an act of decommissioning, before resuming talks with Sinn Féin.
14% said this was not necessary, and 14% had no opinion.
