A commission tasked with building Tunisia's nascent democracy will this week examine a draft law which would ban all foreign financing of political parties, a commission spokesman said Sunday.

The new law, which has been drafted for several weeks, notably bans all direct and indirect foreign funding of Tunisian parties, with jail terms possible for those in breach, commission spokesman Samir Rabhi told AFP.

The draft law to be examined Wednesday would also lower limits on private donations to parties.

Rabhi said the commission expected "strong resistance" from some of the political parties.

Tunisia's Islamist movement Ennahda (Renaissance) has already pulled out of the national commission, challenging its legitimacy.

The reform panel was set up in February after the popular uprising that ousted president Zine el-Abidine Ben Ali on January 14, with a brief to pave the way for democratic change in the north African country.

The leader of the Progressive Democratic Party (PDP), Ahmed Nejib Chebbi, which seeks to be an alternative to the Islamists, has also been critical of the reform panel, arguing that it is "not widely representative" because its members are not elected.
