Switzerland has agreed to return to Nigeria millions of dollars stolen by the former military ruler Sani Abacha.
It says that Swiss authorities struck a deal with Nigeria to hand back $321m (£226m).
The money will only be returned once its agreed exactly how this will be done.
Gen Abacha was in power from 1993 to 1998 and is thought to have stolen more than $2bn of public funds – some of it being deposited in Swiss bank accounts.
Switzerland has already returned more than $720m of the money.
