Greece’s ruling New Democracy party suffered a setback in Sunday’s runoff elections for regional governors and mayors, losing the country’s two largest cities and five of the six regional contests. Prime Minister Kyriakos Mitsotakis had explicitly said that his goal was to win all 13 regions plus the cities of Athens, Thessaloniki and Piraeus, “13 plus 3,” as he said. The results of the first round, last Sunday, appeared to consolidate New Democracy’s political dominance, already expressed in the double national election, last May and June.
