Turkish President Recep Tayyip Erdogan said on Thursday his AK Party would fight until the High Election Board (YSK) gives a final ruling on the March 31 local elections. The statement comes a day after the main opposition candidate took the Istanbul mayor’s office. After 17 days of objections and recounts, Ekrem Imamoglu took office on Wednesday, despite a pending request by the AKP to annul and repeat mayoral elections in Istanbul, Reuters reports. Erdogan also told union members that Turkey needs to use the next 4 1/2 years until scheduled elections effectively and tackle economic and security problems.
