The statement comes after a major rift between Erdogan and the ruling Justice and Development Party (AKP) in the run up to the June 7 parliamentary election where the AKP will seek to change the constitution to give Erdogan's office more executive powers.
"If the president was elected by a public vote, it would be correct for this system to switch to a presidential one," Ahmet Davutoglu said in an interview with private Haberturk television late yesterday.
Davutoglu said the current system was causing confusion over power sharing and it should either be a clear parliamentary system or a clear presidential one so that whoever has power is held accountable.
"Our president is right: it shouldn't be half- parliamentary or half-presidential," he said, adding that there was "no disagreement at all" between him and Erdogan since they were "old friends".

Erdogan, who led the Turkish government for 11 years, has stretched the powers of the once-ceremonial presidency since winning it in August last year in the first ever direct vote, with opponents warning of his growing authoritarianism.
Former foreign minister Davutoglu was expected by some observers to have been a mere puppet of president, but he is now showing ambition to be a high profile prime minister.
An unprecedented rift emerged last week between Erdogan and the government over the handling of the peace process to end the decades-long armed struggle by Kurdish militants.
