Isabel dos Santos: 'Education is our gap in Angola'

The slump in global commodity prices has affected several countries where oil production forms a major part of the economy.

The IMF has warned Angola about its public finances, estimating that debt will climb sharply to 57% of GDP by the end of the year.

As part of the BBC's 100 Women season, Tanya Beckett caught up with Isabel dos Santos, daughter of the Angolan President and Africa's richest woman.

She started by asking her about what she believes to be the biggest obstacle to growth in Angola.
