2022 Tunisian constitutional referendum turned Tunisia into a presidential republic, giving the president sweeping powers while largely limiting the role of the parliament.

The president appoints a prime minister, the nominee of the winning party in the parliamentary election, the one that holds the largest number of seats in the assembly.

This office was created in 1759 with the beginning of the rule of Ali II and Rejeb Khaznadar was the first to take it, becoming the first prime minister in the history of Tunisia.

With its creation, this office was the preserve of the Mamluks of foreign origin who were brought to Tunisia at a young age in order to serve the Royal Family and the Makhzen, such as Mustapha Khaznadar, Kheireddine Pacha and others.

There were two exceptions related to Mohamed Chenik (1943 and 1950) and Tahar Ben Ammar in 1954 who were part of the Destour Party and were appointed by the Bey, and this caused a crisis, especially in 1943 because Muhammad VII Munsif did not coordinate with the French General Resident the appointment of the new prime minister, which caused a political crisis that led to his dismissal.

The nominee must submit its program to the Assembly of the Representatives of the People and get the trust of the majority of its members before being formally appointed prime minister by the president.
