TOURISTS heading to Greece are being warned to take euros in cash as the country's financial situation remains precarious in the wake of the Greek people's No vote in the debt deal referendum.

Withdrawals have been limited to 60 euros a day for locals as cash reserves in the country reach a critical level amid fears that the country is heading towards economic collapse.

The nation's rejection of creditors' terms for a bailout deal leaves the country's future in the EU hanging in the balance, with commentators warning of a catastrophic financial crash that could send it spinning out of the single currency.

Banks closed on June 28 and will stay shut until at least the close of business today, according to the Foreign and Commonwealth Office (FCO).

The latest advice from the Foreign and Commonwealth Office said: "Visitors to Greece should be aware of the possibility that banking services, including credit card processing and servicing of ATMs, throughout Greece could potentially become limited at short notice.

"At this time, you can continue to withdraw cash using your card as normal, up to the daily limit imposed by the Greek banking system, usually 600 euro, or the daily limit imposed by your card issuer, as long as the ATM has been replenished.

"While banks are closed in Greece and some withdrawals are limited, make sure you take sufficient euros in cash to cover the duration of your stay, emergencies, unforeseen circumstances and any unexpected delays."

Tourists are also being warned about potential dangers to their personal safety with regular demonstrations and strikes taking place.

"You should take appropriate security precautions against theft," the FCO said.

"There are regular strikes. These are sometimes called at short notice and can cause disruption to public transport in and out of Greece, including air travel and ports.

"Demonstrations take place regularly in central Athens, and have also taken place in other towns and cities."

The Foreign Office is advising tourists to Greece to take any medicines they might need with them following reports of a shortage of medical supplies.
