Thousands of demonstrators have marched to the streets of Tunisia’s capital to protest the president.
Parallel demonstrations by diametrically different political movements were organized in Tunis.
Both organisations condemned Kais Saied as an autocrat who is undoing the democratic gains gained since the 2011 revolt.
They also demanded accountability for the country’s economic crisis which has seen food and fuel shortages.
Critics of Mr Saied accuse him of staging a coup and attempting to turn Tunisia back into an autocracy – a system of government run by one person with absolute power.
After sacking the prime minister and suspending parliament in July 2021, a year later Mr Saied pushed through a constitution enshrining his one-man rule after a vote boycotted by the main opposition parties.
The new constitution replaced one drafted three years after the Arab Spring in 2011 which saw Tunisia overthrow late dictator Zine al-Abidine Ben Ali.
It gave the head of state full executive control, the supreme command of the army, and the ability to appoint a government without parliamentary approval.
Mr Saied has said it was needed to break a cycle of political paralysis and economic decay.
He said his reforms were being done in the spirit of the 2011 revolution and would ensure a better future.
His supporters welcomed his actions, saying the country needed a strong leader to tackle what they see as a fractious and corrupt system.
On Saturday, protesters in central Tunis chanted, “down, down”, “revolution against dictator Kais” and “the coup will fall”.
One of the marches was organised by the National Salvation Front, a coalition of opposition parties including the Islamist-inspired Ennahda that had dominated Tunisia’s parliament before its dissolution by Mr Saied.
Ali Laarayedh, Tunisia’s former prime minister and a senior Ennahda official, told AFP news agency that the protest was an expression of “anger at the state of affairs under Kais Saied”.
“We are telling him to leave.”
He added that if Mr Saied remains in power, “Tunisia will have no future”, citing growing despair, poverty, and unemployment.
The National Salvation Front has announced it will boycott a December vote to elect a new parliament with limited powers.
Ennahda’s deep ideological rival, the secular Free Destourian Party, also organized a protest in the capital on Saturday.
Some of its protesters carried empty containers to symbolise the rising cost of water due to inflation, which hit 9.1% in September.
Mr Saied “is doing nothing, and things are only getting worse”, said Souad, a pensioner in her 60s.
Around 1,500 people joined the Ennahda-led demonstration, while nearly 1,000 attended the PDL protest, the interior ministry told AFP.
Tunisia’s revolution in 2011 is often held up as the sole success of the Arab Spring revolts across the region – but it has not led to stability, either economically or politically.
The cash-strapped country reached a preliminary agreement with the International Monetary Fund on Saturday for a rescue package loan of $1.9bn (£1.7bn) to help it restore economic stability and strengthen social safety nets.
