Enda Kenny is in Brussels for a Eurozone summit this evening - amid reports that member states have been told to prepare plans for Greece to leave the single currency.
EU leaders are also discussing how to try to grow the economies of member states, in the face of the problems with the Euro.
Earlier, the Taoiseach said that he is not in favour of a eurozone financial transaction tax, if it would put the Irish economy at a disadvantage.
He made the comment ahead of tonight's gathering - which is seen as a pre-cursor to a full leaders summit next month:
"Our view on financial transaction is very clear for quite some time, we do not support that where there would be a disadvantage to our country".
