N'DJAMENA, May 1, 2018 (News Wires) - Chad's parliament overwhelmingly approved on Monday a new constitution that expands President Idriss Deby's powers and could allow him to stay in office until 2033, in a vote boycotted by most opposition lawmakers. The new constitution reimposes a two-term limit scrapped in a 2005 referendum. But it will not be applied retroactively, meaning Deby could serve two terms after the next election in 2021. The constitution now heads to Deby for his signature. The new constitution - approved Monday by a vote of 132 to two - introduces six-year rather than five-year presidential terms.
