The crowd, which grew by about 1,000 people walked the Avenue Habib Bourguiba, sings the national anthem and shouting against the former party and a former president, who left the country last week in the center of popular rebellion.
People walked towards a line of police officers and found himself face to face, but there was no conflict. Witnesses said the police behavior seemed more relaxed than in previous days with the officials who occupy their land, but do not act aggressively.
This is unlike the other days in Tunis, when police fired tear gas and dispersed a peaceful march in which crowds with batons.
As the protesters chanted, a military helicopter flew over the city and drew an ovation from the crowd, you see the Army as a factor of calm in the conflict in the street and go to the police, in line with former President Zine El Abidine Ben Ali and his Constitutional Democratic Rally party.
This comes as the Tunisian officials trying to keep alive the country's coalition government, formed earlier this week with members of the opposition party and Ben Ali.
But the administration had difficulties because the protesters will demand to do more to sweep the old guard to power.
Acting President of Tunisia and the Prime Minister has resigned from the ruling party ousted leader said Tuesday on state television, a move seen as a gesture to appease the protesters on the streets in anger and to maintain unity government afloat.
But at least four ministers from opposition parties have pulled back the new government, leaving some observers fear that the coalition may collapse before creating a new election.
Asked if the unity government is broken if the protests continue, Minister for Social Welfare Moncer Rouissi said that everyone has the right to demonstrate but not to stop the government in carrying out its duties.
