Computer files with more than 100 000 names, nationalities, account information and detailed notes between the Swiss arm of Europe’s biggest bank HSBC and its clients are out in the open.

So far, they have revealed how the vast majority of clients linked to African countries do not hold the nationality of their associated country.

But that was just the start. When looking at the amounts banked by a single client, the results were staggering. Eritrea – ranked 182nd out of 187 countries in the 2014 United Nations Human Development Index (HDI) report – topped the list, with a single client banking a whopping $695.2-million.

Other African countries with clients that featured in the Swiss Leaks’s top 10 list, but also in Africa’s HDI bottom 10, are Chad and the Democratic Republic of Congo.

The International Consortium of Investigative Journalists (ICIJ), which obtained the leaked files and created a database, have revealed who some of these wealthy clients are. They came from a variety of backgrounds, from businesspersons to entertainers – who will have made their wealth legitimately, plying their trades – to politicians and even a hostage negotiator.

But not all of the clients could claim to have made their money legitimately. Some of the revealed names included a collection of international outlaws – from tax dodgers and arms dealers to drug smugglers and money launderers.

Here we take a look through the ICIJ’s personal files and dig out the African names, giving us a closer look at who may, or may not, have wanted the documents kept secret:

Rachid Mohamed Rachid, Egypt

Rachid was Egypt’s minister of trade and industry from 2004 until he fled Cairo, shortly after the uprising that ousted President Hosni Mubarak began in early 2011. Before entering Cabinet, he played prominent corporate roles in international business.

In three trials held in Egypt during 2011 and 2014, the former minister was convicted in absentia, and sentenced to a total of 35 years in prison. He was also ordered to pay at least $330-million for illegal profiteering and squandering public funds.

According to an Egyptian media report, local authorities have been “investigating Rachid’s accounts since he fled the country, and have reportedly sought Interpol intervention in apprehending both him and his daughter abroad”.

In 2013, Rachid settled two other corruption charges by paying a fine of about $2.2-million to Egyptian authorities. He was the beneficial owner of a client account under the name “Lexington Investments Limited” that listed 10 bank accounts. Together they held as much as $31-million in 2006/ 2007.

By the end of 2015, the Seriti Commission of Inquiry, assigned by President Jacob Zuma, is expected to issue a report about Hlongwane’s alleged involvement in “fraud, corruption, impropriety or irregularity in the Strategic Defence Procurement Packages” for the 1999 multibillion-dollar arms purchase by South Africa from BAE.
