"I reallydesperately want to stay in the euro," he said, explaining thatthe referendum regards how to stay in the eurozone, not whetherto stay. Greece's talks with creditors have ground to a haltawaiting the referendum results. European Commission PresidentJean Claude Juncker "fully supports [Greece's] determination tobe part of Europe and to remain part of the euro area", hisspokesman said. "We will simply await the outcome of thereferendum on Sunday. Now is the moment for the Greek people toshape their future," the spokesman, Margaritis Shine, added.Eurogroup President Jeroen Dijsselbloem, however, warned that a"no" vote would not bolster Greece's negotiating position andwould also place Athens and Europe in a "very difficult"position. On the contrary, those who vote "yes" would helpimprove chances of talks resuming, he said. The referendum, hestressed, will reveal whether Greeks are ready to acceptausterity measures. After Moody's, Standard & Poor's alsowarned Greece that a "Grexit" would have "severe consequences"for the country's economy and banks, while the impact would be"more contained" for the rest of the eurozone, possibly withoutimmediate repercussions on the other member states' ratings.Nikos Pappas, the right-hand man of Greek premier AlexisTsipras, stated that Greek banks will reopen once an agreementis reached, while Greek President Pokopis Paulopoulos cancelledhis planned visit to Berlin next Tuesday.
