ANKARA: President Recep Tayyip Erdogan is presiding over the first meeting of Turkey’s new Cabinet led by a trusted ally, in a clear sign that he intends to maintain influence on the running of government. Erdogan on Sunday appointed Binali Yildirim as prime minister. Yildirim promised to immediately work toward a constitutional overhaul that would increase the powers of the largely ceremonial presidency. He replaced Ahmet Davutoglu, whose support for a powerful presidential system seemed lukewarm. Erdogan chaired the new government’s first meeting at his palace on Wednesday. Constitutionally, the prime minister has executive powers in Turkey. But Erdogan, a former premier, has continued to wield powers from behind the scenes. He is pressing for constitutional changes for an all-powerful presidency.
