In total, more than $ 100 billion has been in the approximately 18,000 accounts in the new leak from Credit Suisse.
SVT Nyheter and Uppdrag granskning have together with the international excavation editorial staff OCCRP and 46 other media partners reviewed the material, which has resulted in a number of revelations.
Now there are strong reactions from political parties.
The European People's Party (EPP), which is the largest of the political groups in the European Parliament, believes it is time for the EU to evaluate your relationship with Switzerland.
"When Swiss banks fail to apply international anti-money laundering tools, Switzerland becomes a high-risk jurisdiction," said EPP Markus Ferber in a statement.
Iran, Syria and North Korea on the list
Countries that are considered to have shortcomings in their work against money laundering and terrorist financing may end up on the European Commission's list of high-risk nations.
At present, there are just over 20 countries on the list - for example Iran, Syria and North Korea.
"When the list of high-risk third-party countries regarding money laundering is to be reviewed next time, the European Commission must consider adding Switzerland to that list," says Markus Ferber.
There are also demands for reform in Switzerland.
Both from the Social Democrats and the Greens, who after the revelations want to review Swiss bank secrecy.
Credit Suisse denies in a statement the allegations in the leak and says that they follow all laws and regulations.
The bank argues that the customers in question make up a small part of their total business and that many of the cases are historical.
Credit Suisse has published a longer response on its site after the review.
