Slovak Prime Minister Robert Fico appealed Monday for EU leaders to stop calling referendums that imperil the entire bloc, Reuters reported.

"I am asking EU leaders to stop with adventures like the British and Italian referendums ... on domestic issues which pose a threat to the EU," Fico said.

The United Kingdom voted to leave the EU in June, and in December, Italians rejected constitutional reforms — prompting the resignation of Prime Minister Matteo Renzi.

Euroskeptic parties in the Netherlands and France are calling for referendums on EU membership, while in Italy the 5Star Movement wants a referendum on the country's membership in the eurozone.

"What will we do if ... there is a referendum in Italy on the euro and Italian citizens decide they don't want the euro?" Fico asked Monday, after Slovakia handed the six-month presidency of the Council of the EU to Malta on January 1.
