Supporters of Turkish President look at early presidential election results displayed on a screen of the Justice and development Party (AKP’s) headquarters after polls closed in Turkey's presidental and parliamentary elections, in Istanbul, on May 14, 2023. Turkish polling stations have closed in a knife-edge election that could end President Recep Tayyip Erdogan's two-decade grip on power and put the mostly Muslim nation on a more secular course. Turnout was expected to be huge in what has effectively become a referendum on Turkey's longest-serving leader and his Islamic-rooted party. (Photo by OZAN KOSE / AFP)
