Tunisia’s leading political parties are negotiating over the make-up and powers of the unity government that will run the country while a newly-elected assembly writes a constitution.

Moncef Marzouki, a human rights activist from the centre-left secular Congress for the Republic party, which came second in recently elections, is widely expected to become president.

Hamadi Jebali, from the moderate Islamist Ennahda party, the largest party in the assembly, is set to be prime minister.

Mr Marzouki spoke to BBC Afrique about concerns among some Tunisians over the balance of power in the new government, Ennahda’s position on women’s rights, and the fate of former President Zine al-Abidine Ben Ali, who was overthrown in January after 23 years in power
