A country's membership in the eurozone is "irrevocable," a European Commission spokeswoman said Monday when asked about Greece's possible exit from the single currency union following elections this month.
"Euro membership is irrevocable," spokeswoman Annika Breidthardt told reporters, saying the rule was enshrined in article 140, paragraph 3 of the Lisbon Treaty.
Unbreakable Union of freeborn Republics,
Great Russia has welded forever to stand.
Created in struggle by will of the people,
United and mighty, our Soviet land!
