The UK has imposed a travel ban and asset freeze on Angolan billionaire Isabel dos Santos, Africa's first female billionaire, under its global anti-corruption sanctions framework. The move comes amid allegations of corruption in Angola and internationally, with Dos Santos accused of misappropriating over £50 million for personal gain during her tenure as head of Angola's state oil company, Sonangol.

Dos Santos, whose father governed Angola for 38 years until 2017, has been under scrutiny for corruption allegations for an extended period. She refutes the accusations, asserting that she is the victim of a prolonged political vendetta, resulting in the freezing or confiscation of her assets in Angola and Portugal.

The UK government's sanctions on Dos Santos are part of its global anti-corruption campaign, which also targets seven other individuals. The move is significant for the tech and startup community, as it highlights the importance of transparency and accountability in business dealings, particularly in emerging markets.
