Crunch talks as tourists told to take euros with them to Greece

In an uncompromising joint message after preparatory talks in Paris, Angela Merkel and Francois Hollande said Athens had yet to demonstrate that it was ready to shoulder its share of responsibility.

The urgency of the situation was starkly underlined by the decision of the European Central Bank (ECB) effectively to make it harder for struggling Greek banks to access emergency credit.

That could lead to still-tighter restrictions on cashpoint withdrawals and means branches are unable to open again in the next few days at least.

Markets had remained relatively stable despite the Greek people apparently edging their country closer to leaving the central currency with a decisive rejection of the terms of a new international bailout in Sunday’s referendum, .

After dropping by more than 70 points this morning, the FTSE 100 Index closed 50.1 points lower at 6535.7, after the Greek vote edged it closer to leaving the euro.

As the European Union faced what is widely seen as the deepest crisis in its history, Prime Minister David Cameron spoke to Ms Merkel and met with Chancellor George Osborne and Bank of England Governor Mark Carney to discuss contingency plans in place to protect UK businesses, banks, holidaymakers and the 40,000 expats living in Greece.

Downing Street made clear that Mr Cameron believes Athens and its eurozone partners must now work together on a sustainable solution to the problems caused by Greece’s failure to keep up interest payments on its international debts.

His official spokeswoman declined to say whether the PM thought the solution should involve Greece leaving the single currency.

Pensions continue to be paid as normal to expat Britons living in Greece, with 2,000 people advised on switching payments to non-Greek bank accounts and measures have been put in place to support British firms facing cashflow problems as a result of capital controls imposed by the Greek government, he said.

Staffing levels have been increased at the UK embassy in Athens, and more consular staff have been deployed on the islands of Crete, Corfu, Rhodes and Zakynthos to help British nationals.

Following the result, finance minister Yanis Varoufakis stepped down from his post, saying that some eurogroup leaders had made clear a fresh agreement with creditors would be more likely if he was not part of future talks.

As they began a working dinner to discuss the crisis, Ms Merkel and Mr Hollande each delivered a brief statement in which they made clear they respected the democratic verdict of the Greek people to reject the bailout terms.

But the German Chancellor - the most influential voice among the creditors meeting to hear Mr Tsipras’ latest proposals today - made clear she saw the rejected terms as being “very generous”.

“The door remains open to discussions. That is why the eurozone heads of state and government will meet tomorrow,” she said.

British tourists are not advised to steer clear of Greece, but recommended to make sure they take “sufficient euros in cash to cover the duration of your stay, emergencies, unforeseen circumstances and any unexpected delays” as well as to take security precautions against theft. The advice adds: “There are currently no restrictions on taking unspent euros out of Greece.”
