But while Mr. Erdogan has turned his claimed victory into a political reality, the legitimacy of his win is still in question. Opposition parties say the vote was rigged. The main opposition party formally asked Turkey’s electoral commission Tuesday afternoon to reassess the contents of multiple ballot boxes and — in a separate appeal — to annul the entire poll result. And two major international observation missions have a list of concerns over irregularities during the campaign and on the day of the vote.
One observer group said that 2.5 million votes — roughly twice the margin of victory — are under question. “It seems credible that 2.5 million were manipulated, but we are not 100 percent sure,” Andrej Hunko, a German lawmaker who observed the election on behalf of the Council of Europe, said by telephone.
