Tourists travelling from Ireland to Greece are being advised to take more than one means of payment with them.

The Greek government has confirmed that tourists are not affected by the ATM withdrawal limits of €60 a day for Greeks.

However, the Department of Foreign Affairs is advising visitors to Greece to be aware that banking services - including credit card processing and servicing of ATMs - could potentially become limited at short notice.

Irish citizens are encouraged to ensure they have enough money to cover emergencies, unforeseen circumstances and any unexpected delays - as well as to take appropriate security precautions.

Officials in the Department of Foreign Affairs say they are are working closely with colleagues in the Department of Finance to monitor all developments in Greece.

In a statement, the department says: "We have contingency plans in place that can and will be activated should there be any changes in the situation that may affect our citizens."

However, the Irish embassy in Athens has not yet reported an increase in requests for assistance from citizens.
