People in Moldova have backed the Eastern European country's proposed changes to its constitution and commitment to joining the EU by the thinnest of margins in a referendum. Official data put Yes on 50.46% and No on 49.54% on Monday afternoon, with more than 99.6% of votes counted.

Moldova's pro-EU authorities narrowly succeeded in having passed the constitutional referendum on the country's European path held on October 20, with significant challenges ahead for president Maia Sandu as she faces a difficult second-round presidential vote.

A knife-edge margin of 50.09% voted "yes" in Moldova's pivotal referendum on joining the European Union, partial results showed on Monday, after President Maia Sandu said Sunday's twin votes had been marred by "unprecedented" outside interference.
