Isabel dos Santos got access to lucrative deals involving land, oil, diamonds and telecoms when her father was president of Angola, a southern African country rich in natural resources.
The documents show how she and her husband were allowed to buy valuable state assets in a series of suspicious deals.
Ms Dos Santos says the allegations against her are entirely false and that there is a politically motivated witch-hunt by the Angolan government.
The former president's daughter has made the UK her home and owns expensive properties in central London.
