Angola's former president Jose Eduardo dos Santos has denied links to alleged public company embezzlement during his rule, in his first response to corruption investigators last month freezing his daughter's assets.
Isabel dos Santos, the ex-president's billionaire first-born, has been the target of an anti-corruption campaign led by her father's successor President Joao Lourenco.
The investigation is looking at alleged irregularities involving diamond marketing firm Sodiam and Sonangol -- Angola's national oil company, which was handed over to Isabel dos Santos by her father in 2016.
