Africa's richest woman 'ripped off Angola'

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.

Nicki Minaj: Hip-hop star criticised over plans for Angola Christmas concert

Minaj is due on stage on Saturday in the Angolan capital, Luanda, for a Christmas concert hosted by Unitel, a communications firm that is part owned by dos Santos's family.

Fellow US singer Mariah Carey was criticised in 2013 for performing in front of dos Santos, who has governed the southern African nation for 36 years.
