Slovakia ready for option that Greece exits euro zone: PM Fico

"We wish for Greece to remain in the euro zone but not at any cost," Fico told a joint news conference with visiting British Prime Minister David Cameron.

"Slovakia is prepared mentally and technically for the crisis scenario of Greece exiting the euro zone. We will insist on Greece doing its homework," added Fico, whose country uses the euro.

Euro zone leaders will hold an emergency summit on Monday to try to avert a Greek default as Athens and its international creditors remain deadlocked over a debt deal.
