TUNIS, Tunisia (AP) — Tunisia’s main opposition coalition said Tuesday it won’t take part in the North African country’s upcoming presidential election unless President Kais Saied’s political opponents are freed and judicial independence is restored.

More than 20 political opponents have been charged or imprisoned since Saied consolidated power in 2021 by suspending parliament and rewriting the country’s constitution. Voters weary of political and economic turmoil approved his constitutional changes in a 2021 referendum with low turnout.

Saied is widely expected to run in the presidential election, likely to take place in September or October. It is unclear if anyone will challenge him.

The National Salvation Front, a coalition of the main opposition parties including once-powerful Islamist movement Ennahdha, expressed concern that the election wouldn’t be fair, and laid out its conditions for presenting a candidate.
