Isabel dos Santos faces charges in her native Angola. The daughter of the former long-time president is accused of corruption after a leak of documents. Ed Cropley, former Reuters sub-Saharan Africa bureau chief, discusses what could happen next. Mark Hays from the campaign group Global Witness explains why the role of international banks and accountants in the scandal shouldn't be a surprise. Tom Keatinge from the Royal United Services Institute, a think tank, argues that countries like the UK have made some progress in tackling money laundering.
