"Panama Papers Q&A: What is the scandal about?
A huge leak of documents has lifted the lid on how the rich and powerful use tax havens to hide their wealth. The files were leaked from one of the world's most secretive companies, a Panamanian law firm called Mossack Fonseca.
What are the Panama Papers?
The files show how Mossack Fonseca clients were able to launder money, dodge sanctions and avoid tax.
In one case, the company offered an American millionaire fake ownership records to hide money from the authorities. This is in direct breach of international regulations designed to stop money laundering and tax evasion."
