Gabon has lifted its presidential term limit thus allowing President Ali Bongo remain in power indefinitely.
The National Assembly voted overwhelmingly in favour of the new constitution which allows the unlimited renewal of the presidential seven-year term.
Also amended is that the president will be immune from prosecution during and after his time in office.
The opposition party are not pleased with this calling it an attempt to turn Gabon into a monarchy.
Mr Bongo took office in 2009, after the death of his father, Omar Bongo, who ruled the country 42 years.
