A total of 98 people including Tunisia’s prime minister have submitted their documents to run for president.
The country’s electoral commission set Friday as deadline for registration of candidates.
Parliamentary elections were originally scheduled for Oct. 6 with a presidential vote following on Nov. 17.
But the elections were brought forward following the death of Beji Caid Essebsi late last month.
The electoral commission has now announced that a presidential election will take place on Sept. 15, two months earlier than scheduled. A parliamentary vote is set for Oct. 6.
Chahed, 43 is Tunisia’s youngest prime minister. He could face competition from Abdelfattah Mourou of the Islamist-inspired Ennahdha party.
Controversial media magnate Nabil Karoui is also another person to possibly give Chahed a fierce competition.
Tunisian former president Moncef Marzouki also wants to stand, as well as Defence Minister Abdelkrim Zbidi, 69.
On August 31, the electoral commission will rule on which candidates meet the criteria to stand, with campaigning due to start on September 2.
