Sudan’s President Omar al-Bashir has been re-elected with 94% of the vote, according to official results.
His victory, which was widely expected, means he can now extend his 25-year rule by a further five years.
The country’s main opposition parties boycotted the elections. Turnout was about 30-35%, African Union observers said.
Mr Bashir denies International Criminal Court charges of ordering a genocide in the Darfur conflict.
Official turnout was 46.4%, but the BBC’s James Copnall, who reported on the elections from Khartoum, says many believe the real figure was even lower.
Western countries, including the US, Britain and Norway, criticised the polls for not being free and fair.
The African Union monitors said that basic freedoms and human rights would have “enhanced” the polls.
