Asked on his return from a visit to Saudi Arabia late on Thursday whether an executive presidency was possible in Turkey while maintaining the unitary structure of the state, Erdogan said: "There are already examples in the world. You can see it when you look at Hitler's Germany.
"There are later examples in various other countries," he told reporters, according to a recording broadcast by the Dogan news agency.
Erdogan wants to change the Turkish constitution to turn the ceremonial role of president into that of a chief executive, a Turkish version of the system in the United States, France or Russia.
The ruling AK Party, founded by Erdogan, has put a new constitution at the heart of its agenda after winning back a majority in a November parliamentary election. source
