Eurozone membership is 'irrevocable', EU says ahead of Greek elections

BRUSSELS (AFP) - A country's membership in the eurozone is "irrevocable," a European Commission spokesman said on Monday when asked about Greece's possible exit from the single currency union following elections this month.

"Euro membership is irrevocable," according to the EU treaty, spokesman Annika Breidthardt told reporters ahead of Greek elections on Jan 25 with a far-left anti-austerity party leading in opinion polls.
