Some 35 per cent of the public blame Sinn Fein and the IRA for the stalemate in the peace process, according to an IMS/Sunday Independent poll.
Some 30 per cent blamed the Ulster Unionist Party while 26 per cent blamed the British government.
Only 4 per cent of the respondents blamed the Irish government while 20 per cent expressed no opinion.
The results come ahead of a crucial week during which the Irish and British governments will try to revive the peace process.
The Taoiseach, Mr Ahern, and the British Prime Minister, Mr Tony Blair, will meet tomorrow at Downing Street with the main parties supporting the Belfast Agreement.
Mr Ahern and Mr Blair will hold separate discussions with representatives of the Ulster Unionist Party, the SDLP and Sinn Fein. Government officials in Dublin and London have for several weeks been preparing a position paper on how all aspects of the Belfast Agreement could be implemented.
Meanwhile, even without IRA decommissioning, some 45 per cent of the respondents to the IMS poll "think that Sinn Fein ministers should be included in any coalition government formed" in the event of a hung Dail after the next general election. This is a 1 per cent increase since the last IMS poll in February. However, opposition to such an eventuality has hardened, up 5 per cent to 41 per cent.
Those not expressing an opinion have declined to 13 per cent from 21 per cent in February.
A majority (55 per cent) disapproved of the Orange Order march planned for Dublin on May 28th. Some 29 per cent said they approved while 16 per cent expressed no opinion.
