The former president is being detained in a cage within the courtroom
Sudan's ousted President Omar al-Bashir admitted to receiving millions of dollars from Saudi Arabia, an investigator has told a court in the capital, Khartoum.
The former leader is facing corruption charges related to the illegal possession of foreign currency.
The military authorities say cash was found at his home after he was deposed by the military in April.
"The accused told us that the money was part of a sum of $25m (£20m) sent to him by Prince Mohammed bin Salman to be used outside of the state budget," investigator Ahmed Ali is quoted by the AFP news agency as saying.
Mr Ali said that according to Mr Bashir there had been two earlier payments of $35m and $30m from Saudi Arabia, AFP reports.
