Pro-European Union candidate Nicusor Dan has won Romania’s closely watched presidential runoff against a hard-right nationalist, nearly complete electoral data shows. A huge turnout Sunday played a key role in the tense election that many viewed as a geopolitical choice between East or West.

Ultranationalist George Simion was the favorite in Romania’s runoff, but concerns over the country’s future sparked record turnout. Pro-EU Nicușor Dan’s win brings relief to Brussels and Kyiv.
