Tunisia: Thousands from rival political parties protest against President Kais Saied

Thousands of protesters have taken to the streets of Tunisia's capital to demonstrate against the president.

Parallel demonstrations by political movements who are deeply opposed to each other were held in Tunis.

Both groups denounced Kais Saied as an autocrat who is reversing the democratic progress made since the 2011 uprising.

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.

The new constitution replaced one drafted in 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, 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 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 organised 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.

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 economically or politically.

The cash-strapped country is in talks with the International Monetary Fund for a bailout loan of about $2bn (£1.79bn).
