Chad's National Assembly has endorsed constitutional revisions that would extend the presidential term from five to seven years.
It also allows the president to serve an unlimited number of times.
President Mahamat Idriss Deby came to power in Chad after his father, long-serving President Idriss Deby, was killed as he was visiting troops fighting militias in the north of the country in 2021.
He secured victory following an election held after three years of military rule in May 2024. Parliamentary elections followed in December, granting the vast majority of seats to the ruling party.
Awaits the Senate's vote
Chad's new constitution sailed through the National Assembly on Monday and is due for a final vote by the Senate on October 13.
The National Assembly approved the changes on Monday by a vote of 171 in support, one abstention and zero against, its President Ali Kolotou Tchaimi told reporters on Monday.
The Senate will vote on October 13, and then the president is expected to sign the constitution into law.
