Algerians have overwhelmingly approved a peace plan that plans to end a 13-year-old civil war that has killed 150,000.
The deal provides a broad amnesty for Islamic extremists, despite critics' charges it whitewashes past crimes.
Interior Minister Noureddine Yazid Zerhouni said the Charter for Peace and National Reconciliation got more than 97 per cent of yesterday's vote - a giant win that could further strengthen President Abdelaziz Bouteflika. The "no" polled less than 3 per cent.
Nearly 80 per cent of the more than 18 million eligible voters cast ballots, the minister said. In one town, Khenchla in the east, 99.95 per cent turned out.
But the turnout rate was far lower - just over 10 per cent in some towns - in the restive Berber region of Kabylie, where there had been calls to boycott the vote.
Critics of Mr Bouteflika's charter, from opposition politicians to human rights groups and families of people who disappeared in Algeria's bloody Islamic insurgency, had predicted it would easily pass, especially given the lack of real debate.
Civil unrest started in Algeria after the second round of 1992 legislative elections were cancelled. The extremist Islamic Salvation Front, which is now banned, was expected to win the vote.
Mr Bouteflika also won a landslide re-election victory in 2004, five years after taking office following the election tarnished by allegations of fraud.
