Africa's richest woman denies corruption allegation

The daughter of Angola's former president, Isabel dos Santos, has denied allegations of corruption when she was head of the state oil firm, Sonangol.

She described as entirely legitimate a payment of nearly $40m (£29m) to a Dubai-based company after she was dismissed from Sonangol.

She said, under Angolan law, public officials must continue in their roles until a replacement was found.

Last week, the public prosecutor's office opened an investigation into the alleged graft.

Angola's new president Joao Lourenco has taken a number of steps to tackle corruption and nepotism.

Ms dos Santos was fired in November. Her brother José Eduardo dos Santos was removed as head of the country's $5bn (£3.7bn) sovereign wealth fund months later.
