The Taoiseach Brian Cowen will be among the Eurozone leaders who are to meet in an emergency summit in Paris on Sunday to draw up a joint action plan to tackle the financial crisis.
The French President Nicolas Sarkozy's office made the announcement tonight.
EU heads of state and government are due to hold a regular summit in Brussels next Wednesday, but the speed and ferocity of this week's market meltdown has forced the leaders to react faster.
The summit will also bring together European Commission chief Jose Manuel Barroso and Jean-Claude Trichet, president of the European Central Bank, according to the French President's office.
'The meeting's objective will be to define a joint action plan for the eurozone and the European Central Bank in relation to the current financial crisis,' the statement said.
The summit is scheduled to begin at 6pm at the Elysee Palace in the French capital.
Spanish Prime Minister Jose Luis Rodriguez Zapatero had earlier called for an emergency meeting of Eurozone leaders to come up with a coordinated response to the crisis.
Fall in retail sales and building jobs
