Voting has ended in the first multi-party elections in Sudan since 1986.
They are part of a north-south peace deal which ended two decades of war in 2005.
However, the presidential, parliamentary and local polls have been marred by voting irregularities and accusations of rigging. Many opposition parties boycotted all or part of the poll.
The BBC reports President Omar al-Bashir is widely expected to stay in power for another five years.
Mr Bashir, who is wanted by the UN for war crimes in Sudan's western Darfur region, has asked rival parties to join his government if he wins.
Polling began on Sunday and was due to last three days, but was later extended.
