Thousands of Tunisians have marched through their capital calling for the resignation of the Islamist-led government elected two years ago, following the first of the Arab Spring revolts.
The demonstration in Tunis came as the ruling coalition and the opposition prepared for talks aimed at crafting a new government of technocrats within the next three weeks.
The technocratic government will have the task of overseeing upcoming elections.
The protesters fear the government, led by the moderate Islamist Ennahda Party, will not keep its promise to resign as part of the process.
A faltering economy and the assassination of two left-wing politicians have been used as evidence by opposition of the government's failings.
As the birthplace of the Arab Spring revolts, Tunisia's rocky transition to democracy is being closely watched.
