Turkish presidential candidate's withdrawal boosts Erdogan's rival.

Muharrem Ince, one of four candidates contesting Turkey's presidential election, withdrew from the race, giving a boost to Erdogan's main rival, Kemal Kilicdaroglu. A poll by Konda put Kilicdaroglu ahead of Erdogan with 49.3% of the vote, leaving him short of the majority needed to win in the first round. Ince's withdrawal could reshape the last days of campaigning in what is seen as Erdogan's biggest test in his two-decade reign.
