Work on new constitution to go on after main opposition pulls out - Turkish PM
"The main opposition announced it won`t participate in work on a new constitution because they`re unwilling to bring issues such as the executive presidency to the table," Davutoglu said.
"We will continue to be at the table... It is our duty to compromise on a new constitution without any prerequisites ... I call on all opposition parties to be at the table to be able to discuss any issue," he said.
The AKP, founded by Erdogan more than a decade ago, has broad cross-party support for overhauling the constitution, which dates back to an era of military coups, but there are wide divergences over what a new charter should look like.
Erdogan and the AKP want the head of state, currently a largely ceremonial role, to wield much greater political powers. But the opposition wants to focus on minority rights and democratic freedoms and fear Erdogan is becoming too authoritarian, a charge he denies.
