Turkey's incoming prime minister Binali Yildirim on Sunday vowed to make a priority out of implementing the controversial plan of President Recep Tayyip Erdogan for a presidential system in the country.

"Turkey needs a new constitution. Are you ready to bring in presidential system?" Yildirim, who is due to be confirmed as new premier later in the day, told a ruling party congress to cheers from the crowds. 

"What has to be a priority now is moving from the current de-facto system to a legal system," he said.
