On Friday journalist Taoufik Ben Brik, who has been living in exile in Paris, said he will stand for president.

Tunisian state television reports that weapons have been seized at the home of a member of Leila Ben Ali’s family, following Thursday’s arrest of 33 of the ex-president’s relations.
Sources at Tunisia’s Central Bank on Friday denied French media claims that Ben Ali’s wife Leila made off with 1.5 tonnes of gold, worth 45 million euros, from its reserves.
On Tuesday the bank claimed that its stocks have remained at 5.3 tonnes for the lat 20 years. But the World Gold Council puts the figure at 6.8 tonnes.
Le Monde newspaper quoted a French secret services agent as saying that Ben Ali himself bullied the bank’s governor into complying with his wife’s demand, while the TF1 TV station reports that the gold was withdrawn at the end of December.
