The long-serving mayor of Ankara, İbrahim Melih Gökçek, announced his resignation on Saturday.
Speaking at a municipality council meeting, Ankara Greater Municipality Mayor Gökçek said President Recep Tayyip Erdoğan requested his resignation and he is following the president's orders.
"There is no place for harming the cause for personal interests... In my cause, leader's orders must be followed," Gökçek stressed.
Gökçek, who spent 23 years as the capital's top official, quit following Erdogan's call for him and two other Justice and Development (AK) Party mayors to stand down.
The president also demanded the resignations of Bursa Mayor Recep Altepe and Balikesir Mayor Ahmet Edip Uğur.
In recent months, Erdoğan has repeatedly called for elements of the party showing "metal fatigue" to stand aside as it prepares for local, presidential and general elections in 2019.
Istanbul Mayor Kadir Topbaş and Duzce Mayor Mehmet Keleş stepped down over the summer.
Gökçek served five consecutive terms as Ankara mayor after starting his political life as the mayor of the capital's Keçiören district.
A former head of the Social Services and Child Protection Society, he entered parliament in 1991 as an Ankara lawmaker for the Welfare Party. He had previously been a member of the Motherland Party.
After three years in parliament, he stood for and won the mayoralty. He was returned to office in 1999 as the candidate of the Virtue Party, becoming the first Ankara mayor to win two terms.
He later joined Justice and Development (AK) Party and won a third term in 2004.
Gökçek's fourth election win came in 2009, followed by victory in 2014.
