Turkey's ruling party is set to replace Prime Minister Ahmet Davutoglu during a congress later this month.

The decision came after a meeting between Davutoglu and President Recep Tayyip Erdogan, and weeks of increasingly public tension between the two. Erdogan wants an executive presidency to replace the current parliamentary system.

But Davutoglu has offered lukewarm support. Erdogan is critical of Davutoglu's recent signing of a migrant deal with the European Union. The looming change is likely to plunge Turkey into political uncertainty as it faces mounting security challenges.
