Dokolo, a very ambitious man, had a businessman father, Augustin Dokolo Sanu.

In fact, he was reported to have inherited a fortune following his father's death in 2001.

His father, it is recalled, built a business empire considered one of the largest in Zaire under the government of the late Mobutu Sese Seko.

One of his businesses was the Bank of Kinshasa.

Dakolo, as the son of a wealthy man, grew partly in Europe. As he grew, he became a businessman going into various sectors of the economy with de Santos.

Part of his business interests included oil, diamonds, retail, cement and telecommunications. He also went into collection of art and also played a role in the clamour for the repatriation of looted artworks to African museums.

There was  a  report that Isabel dos Santos once hinted at contesting for the Angolan presidency.Dakolo later went into politics and was said to have financed some of the opposition elements at the twilight of Joseph Kabila's era.

In speaking with the BBC, Isabel on four different occasions refused to rule out the possibility that she could be running for the nation’s highest political post.

It should be noted that her father, Jose Eduardo dos Santos, was the president of Angola for 38 years.

Also, prosecutors are trying to recover $1bn (N361,500,000,000) from Isabel and her associates are said to be owing the country.
