A Sinn Féin delegation will meet the Taoiseach in Dublin tomorrow as efforts to restore power sharing in Northern Ireland continue.
The delegation, led by party President Gerry Adams and Chief Negotiator Martin McGuinness will hold discussions with Mr Ahern in Government Buildings at 4pm.
On Thursday morning, a Sinn Féin delegation will travel to London to meet British Prime Minister Tony Blair.
Speaking before the meetings Mr McGuinness today accused the two governments of "pandering to the rejectionist demands of the DUP".
"The proposals put forward for talks, which would have excluded Sinn Fein, is clear evidence of this," he said. "In our view, the two governments must defend robustly and resolutely the principles of equality, inclusivity and mutual respect which underpin the Good Friday Agreement and they must take the lead in resisting DUP attempts to destroy its underpinning architecture and safeguards."
Tomorrow's delegation witll also include Caitriona Ruane MLA, Michelle Gildernew MP, Cllr Larry O'Toole and Caoimhghin Ó Caoláin TD.
Accompanying Mr Adams and Mr McGuinness to London are Cllr David Cullinane, Ms Gildernew, Conor Murphy MP and Pat Doherty MP.
