SOFIA, Bulgaria (AP) — The center-right GERB party of former Pr ime Minister Boiko Borisov took the lead in Bulgaria's parliame ntary election on Sunday, a pair of exit polls showed, a result that if confirmed by official returns indicates support for th e country keeping its European identity. The Alpha Research exit poll said GERB won 32.2 percent of the vote, with the Socialist Party coming in second with 28 percent , while a separate exit poll by Gallup International Balkan had GERB with 32.8 percent and the Socialists with 28.4 percent. Official results are expected Monday. If they confirm the exit polls, Borisov, a political maverick who combines man-in-the-st reet rhetoric with a pro-European Union disposition, will be ha nded a mandate to form his third cabinet. GERB did not win enough votes to govern alone, and will likely form a coalition government with the United Patriots, an allian ce of three nationalist parties that the exit polls showed plac ing third. Borisov, 57, resigned as prime minister after his party lost th e November 2016 presidential election. Parliament was dissolved in January, and the president appointed a caretaker government that will stay until a new government is formed.
