Protesters from Tunisia's poor rural heartlands demonstrated in the capital on Sunday to demand that the revolution they started should now sweep the remnants of the fallen president's old guard from power.
A week after Prime Minister Mohamed Ghannouchi took the reins of an interim coalition following the overthrow of veteran strongman Zine al-Abidine Ben Ali, he and other former loyalists of the feared ruling party face mounting pressure to step down.
Striving to distance themselves from the old regime, the transitional leadership placed under house arrest two former aides to Ben Ali, who has fled to Saudi Arabia. As with earlier arrests of 33 of his rapacious entourage, details were sparse.
For days, protesters have gathered at the premier's office in Tunis, limited in numbers but tolerated by a police force wary of its own fate after Ben Ali and enjoying wider support among a population that is unused to free political expression.
On Sunday, amid a weekend calm, hundreds of people who had been driven to the capital in a "caravan of freedom" surrounded Ghannouchi's building in central Tunis. Many were from Sidi Bouzid, the bleak central city where the "Jasmine Revolution" was sparked a month ago by one young man's suicide.
Demonstrators said they would not let the legacy of Mohamed Bouazizi, who set himself alight in protest at poverty and oppression, end with Ben Ali's flight to Saudi Arabia and the establishment of a government dominated by his lieutenants.
Former members of Ben Ali's RCD ruling party retain key ministries, notably interior, defence and foreign affairs. Politicians from small opposition parties previously tolerated under Ben Ali were allowed to join the government in less vital posts, such as higher education and regional development.
