Kemal Kılıçdaroğlu, the leader of main Turkish opposition party CHP, has vowed to stop all of Erdogan’s efforts to transform Turkey from a parliamentary system to a presidential system, Hurrieyt Daily News reports. Both Erdogan and Turkish PM Ahmet Davutoglu are currently pushing for a new constitution that would create a presidential system, but the ruling AKP does not have enough seats in the parliament to do so without some support from opposition members.
