TUNIS, Tunisia (AP) — Hundreds of supporters of Tunisian President Kais Saied took to the streets to celebrate after the end of voting on a controversial new constitution that critics say could reverse hard-won democratic gains and entrench a presidential power grab.

President Kais Saied joined a large crowd of supporters early Tuesday as they marched down Tunis' central thoroughfare, waving national flags, cheering and blaring car horns after an unofficial exit poll result late Monday suggested that a majority of voters approved the new constitution. 

Escorted by a strong security detail, Saied told the media he would ensure “a much better future” for Tunisians and pledged improved living conditions while continuing the fight against corruption.

“We have gone from the shore of despair and disillusion to the shore of hope" he said. “There will be no turning back... This is a total break with a system forever rejected"

Many supporters ululated and jostled to get a photo of Saied on their smartphones as he walked down the avenue.

“I wish him victory against his enemies, we hope that God will protect him from the wicked. Congratulations, congratulations, look after yourself Kais Saied!” said one supporter, Haida, who only gave her first name.

According to the Independent High Authority for Elections (ISIE), an official preliminary result is expected Tuesday evening and the final result on August 28.
