South Sudan’s government has proposed a bill that would extend President Salva Kiir’s term in office for three more years.
If it is passed, Mr Kiir would serve until 2021, a total of 10 years in office.
The opposition has condemned the move, saying it violates the spirit of the current peace process.
Mr Kiir’s mandate was already extended by three years in 2015 when it was argued that civil war made elections impossible.
Fighting is continuing in the country, despite a recent ceasefire deal.
