Turkish presidential candidate withdraws, boosting rival's poll lead.

Muharrem Ince, one of the four candidates contesting Turkey's presidential elections, withdrew from the race, giving a boost to Erdogan's main rival, Kemal Kilicdaroglu, who is now leading in the polls by over five percentage points. The election is seen as Erdogan's biggest test in his two-decade reign, complicated by a cost-of-living crisis, triggered by a lira slump and soaring inflation, and a devastating earthquake in February. The Konda poll suggests the election will go to a run-off between Erdogan and Kilicdaroglu on May 28.
