ANKARA -- Turkey's prime minister has officially launched his ruling party's campaign for a "yes" vote in a referendum on ushering a presidential system, which critics fear will concentrate too many powers in the hands of President Recep Tayyip Erdogan.
Binali Yildirim formally got campaigning going on Saturday telling supporters in a sports arena that the proposed new system would build a strong Turkey capable of surmounting terror threats and make its economy more robust.
Yildirim said: "We are taking the first steps on the path of a future strong Turkey."
