Tunisian President Kais Saied's chief of staff and closest adviser Nadia Akacha said on her Facebook page on Monday that she had resigned due to "fundamental differences in opinion" over the country's interests.
Akacha has been Saied's closest aide since he rose to office in a 2019 landslide and since his July moves to suspend parliament and assume executive power in a measure his foes call a coup.
"I decided to resign after two years... I am faced with fundamental differences in opinion regarding (Tunisia's) best interests and I think it is my duty to withdraw," she wrote, without elaborating.
