“It is the responsibility of the Greek government to meet its obligations, firstly with the IMF”, he said.

“The 18 countries, apart from Greece, all said clearly that Greece was in the euro and should remain in the euro whatever the difficulties of the moment”, he added.

Valls told Europe 1 radio and the Le Monde daily that the referendum which the Greek government has announced for July 5 will decide the country’s future in the euro zone.

“France is available at any time to resume dialogue with Greece… we are available today, tomorrow, the day after tomorrow…to try to find a solution that is solid and stable for Greece”, Sapin said.

Alexis Tsipras’ leftist government had seen its hopes of building an anti-austerity alliance with France dashed when it came to power in January, with Paris insisting it would act jointly with Germany over Greece’s debt crisis.

The current financial assistance arrangement with Greece will expire on 30 June 2015, as well as all agreements related to the current Greek programme including the transfer by euro area Member States of SMP and ANFA equivalent profits. Greece’s Finance Minister Yanis Varoufakis won’t take part in the second meeting now underway in Brussels, Dijsselbloem said.

“It is obvious that if there is a negative response, there is a real risk… of leaving the eurozone”, Valls told rolling news channel iTELE.

Valls urged the European Central Bank to continue supplying Greece with cash as governors held emergency talks before Greek banks open on Monday.

“The European Central Bank is independent but…” “I don’t think it can cut off support, to put it another way”.
