Turkish presidential candidate Ince withdraws days before vote

Turkish presidential election candidate Muharrem Ince, one of four contesting Sunday's vote, said on Thursday he was withdrawing from the race, in a potential boost to the main rival of President Tayyip Erdogan.

Ince was one of four candidates in the vote, alongside Erdogan, his main opponent Kemal Kilicdaroglu and Sinan Ogan. A survey earlier showed Erdogan lagging Kilicdaroglu by more than five percentage points ahead of the election.
