As Greece remains defiant, despite talks with its international creditors stuck in deadlock, anger and concern is mounting in Europe about the finale to this Greek crisis.
Following an emergency meeting of the government on Monday -- ostensibly to discuss the failure of talks at the weekend -- Greek Prime Minister Alexis Tsipras blamed creditors for the deadlock, although this was swiftly rebuffed by Europe.
Michael Fuchs, vice chairman of Germany's CDU/CSU - the ruling conservative coalition, led by German Chancellor Angela Merkel -- told CNBC Tuesday that Greece needed to decide whether to stay in or get out of the euro zone.
"It's not a question of whether we are ready (for Greece to leave the euro zone), it's for Greece to decide what they want to do," he told CNBC Europe's "Squawk Box."
"If they are not coming up with any new reform proposals which we have agreed…and now they're breaking the contracts they have with us. They're breaking all the rules."
