Greece's center-right wins big, but faces runoff for single-party rule.

Greece will hold new national elections as early as June 25 after Prime Minister Kyriakos Mitsotakis confirmed he would not try to build a coalition government despite dominating the ballot hours earlier by the most decisive margin in half a century. The one-off electoral law in place Sunday denied him a governing majority, and he'll now pin his hopes on a second vote, expected no later than July 2. With 99.70% of the votes counted, New Democracy has 40.79% and 146 seats, five short of a majority, winning in 58 of the country's 59 constituencies.
