After the pro-democracy Arab Spring revolution, Tunisia became one of the freest countries in the Arab world for journalists to operate.

Saied effectively seized complete power in Tunisia last year, in a move described as "a coup" by opponents, which saw parliament and the government dissolved.

 and democracy now appear to be on a rapid decline under the autocratic rule of President Saied and only set to worsen when the constitution vote passes. 

The Tunisian National Journalists Syndicate has accused the new constitution of "opening the door to removing the spirit of hard-fought freedom, using vague phrases such as ‘public morals’, ‘national security’ and ‘public health’ to excuse . 

"This represents a serious regression from the gains made by the Tunisian revolution in this field," e in their statement. 

"Tunisia is once again on the road to personal power, which runs completely counter to the progress made by Tunisians in terms of individual freedoms since the January 2011 revolution," said Khaled Drareni, RSF’s North Africa representative, earlier this month.
