Tunisias electoral commission has approved 27 candidates ahead of Novembers presidential election.
The candidates include the secular politician Beji Caid Essbsi, who was a former foreign affairs minister under strongman Zine el-Abidine Ben Ali.
Another approved candidate is Tunisias current interim president, Moncef Marzouki, a French-trained doctor and human rights activist.
The November election is due to be Tunisias first constitutionally backed presidential poll since the 2011 uprising.
It will be preceded by parliamentary elections in October.
Earlier this month, the countrys interim Prime Minister Mehdi Jomaa announced he would not be standing in the presidential elections, despite being named as a possible consensus candidate by Rachid Ghannouchi, the leader of the moderate Islamist party Ennahda.
