The person who claims to have disclosed the Panama Papers, a trove of financial data that has implicated politicians and business leaders around the world in large-scale tax evasion, issued a statement Friday explaining the motives behind the massive leak.

The leaker said the documents reveal how global income inequality is fed by "massive, pervasive corruption," which the leaker blamed primarily on failings by the legal profession, while condemning the roles played by banks, financial regulators, tax authorities, the courts and the media.

The person did not reveal his or her name or any other identifying information, or explain how the papers were obtained.
