Authorities across the world are being spurred into action after a huge leak of confidential documents revealed how tax havens are used to hide wealth.
Eleven million documents were leaked from the secretive Panamanian law firm Mossack Fonseca.
They show how the company has helped some clients launder money, dodge sanctions and avoid tax.
According to BBC News, the documents show 12 current or former heads of state, and at least 60 people linked to current or former world leaders, in the data. The files reveal a suspected billion-dollar money laundering ring involving close associates of Russia’s President Vladimir Putin.
