What are the Panama Papers?

The Panama Papers might represent the world's largest ever leak of classified documents. There are about 11.5 million internal documents from a Panamanian law firm, Mossack Fonseca. Mossack Fonseca sells "shelf" companies around the world, potentially allowing individuals to conceal their business operations.

Who got the leak?

The papers were first leaked to German newspaper Süddeutsche Zeitung. That paper engaged the International Consortium of Investigative Journalists to help co-ordinate the reporting and research into the documents.
