ANKARA, Turkey, Sha'ban 20, 1436, Jun 7, 2015, SPA -- Turks are heading to the polls in a crucial parliamentary election that will determine whether ruling party lawmakers can rewrite the constitution to bolster the powers of President Recep Tayyip Erdogan, AP reported. Erdogan's ruling Justice and Development Party, or AKP, is expected to win significantly more votes Sunday than any opposition party. But AKP must win a super majority of the 550 seats in parliament to change the constitution. --SPA 11:27 LOCAL TIME 08:27 GMT www.spa.gov.sa/w
