Turkish President Recep Tayyip Erdogan could lose the presidency in Sunday's elections, according to the results of two polls published on Thursday. If none of the candidates passes the 50% barrier, the country's future president will be decided in a second round on May 28.

Two other candidates are running for president but neither currently exceeds 5% of the vote. One of them, Muharrem Ince, withdrew his candidacy this morning, after a sex scandal in which he was allegedly implicated was revealed last night.
