Turkey is a constitutional republic with a largely ceremonial presidential post. Erdogan's former Justice and Development Party (AKP) has been rallying voters ahead of the June 2015 to get enough AKP lawmakers in the parliament to change the constitution.
Speaking at a rally in Bursa, Erdogan accused parliamentary opposition of being "ignorant" about the benefits of the presidential system, stressing it had secure control mechanisms.
He noted that a presidential democracy had a better chance of success due to its ability to make decisions faster.
"Look at the countries that can make decisions faster. The majority of them have a presidential system of governance. If we want Turkey to be among the 20 most developed countries, we must discuss this issue," Erdogan said.
At present, a president in Turkey is elected by the parliament. The backing of at least 330 parliament members is needed to amend the Turkish constitution. The ruling AKP party holds 312 seats.
