Panama Papers.

The Panama Papers are 11.5 million documents from the world’s fourth-largest offshore law firm, Mossack Fonseca, that were leaked by the media in April 2016, revealing a system for wealthy individuals to use offshore tax havens to store money and avoid paying taxes to their nation of residence. As of 2023, the Panama Papers was one of the largest digital data leaks in history, and though much of Mossack Fonseca’s activities are legal, the leak also showed how the company helped clients around the world to violate tax and financial disclosure laws.
